RE: Application to the 20th Expert Committee on Selection and Use of Essential Medicines
to modify the wording of the listing of certain opioid analgesics
Lopik, 20 October 2014,
Dear Dr Magrini,
The 19th Expert Committee on Selection and Use of Essential Medicines decided to add a number of
morphine preparations, including higher dosages and dosage forms for children, to the Model List of
Essential Medicines and the Model List for Essential Medicines for Children. As alternatives, both lists
mention hydromorphone and oxycodone. With these changes, the lists reflect modern approaches to
pain management in adults and in children.
It was me, as the then Team Leader, Access to Controlled Medicine, World Health Organization, who
applied for these additions, with the support of Members of the Guidelines Development Group for
the WHO Guidelines on the Pharmacological Treatment of Persisting Pain in Children with Medical

Illnesses. The application involved the addition of hydromorphone and oxycodone “as an example of
a class” and explicitly requested that the Essential Medicines List (and the one for Children) mention
that “Two or more alternatives to morphine should be available”. This should be expressed in the
lists for example as a footnote to the square box.
In agreement with the WHO paediatric pain guidelines, the applied wording to refer to
hydromorphone and oxycodone was not limiting.
However, the wording of the 19th Model List and the 4th Model List for Children limit the
alternatives to these two opioids by saying “alternatives limited to hydromorphone and oxycodone”,
but there is not any scientific reason for such limitation to these two opioids only, and also there is
no reason to prefer these two alternatives over several other alternative opioids. The chosen
wording is prohibitive for having an optimal number of alternatives available for difficult cases and
therefore it is very unfortunate.
For this reason, I request again that hydromorphone and oxycodone are added and referred
to in a non-limiting manner, i.e. “as an example of a class” and that a footnote be added that
“two or more alternatives to morphine should be available.”
This request is supported by Dr Allen Finley, Chair of the Guidelines Development Group for the WHO
guidelines on the pharmacological treatment of persisting pain in children with medical illnesses, Dr
John Collins, Member of the same Guidelines Development Group and Prof Dr.med. Lukas Radbruch,
President, International Association for Hospice and Palliative Care (IAHPC) and Chair, Palliative
Medicine, University Hospital Bonn and Director, Palliative Care Centre, Malteser Hospital Seliger

Annex 1: application on oxycodone of 21 September 2012, to the 19th Expert Committee on the Selection and Use of Essential Medicines
Application to add oxycodone to the
Essential Medicines List for Children
Summary statement of the proposal for inclusion Pain in children is a public health concern of major significance in most parts of the
world. Although the means and knowledge to relieve pain exists, children’s pain is often not
recognized, is ignored, or even denied. It is important that adequate access to appropriate
opioid medicines be available for the treatment of moderate to severe persisting pain in
children worldwide.
To align the Essential Medicine List for Children (EMLc) with the recently published
WHO guidelines on the pharmacological treatment of persisting pain in children with medical
illnesses [WHO pediatric pain guidelines, 2012: p.78– further referred to as “Guidelines”], it
is necessary to add more opioid preparations to the EMLc. The Guidelines state that if pain
severity associated with a medical illness is assessed as moderate or severe, the administration
of a strong opioid is necessary. In that case morphine is the medicine of choice, although
other strong opioids should be considered and made available to ensure an alternative to
morphine in case of intolerable side-effects. It is advised that two or more strong opioids
should be available for this purpose, and oxycodone is one such strong opioid. Thus, it is
requested that oxycodone be added to the EMLc as an example of the opioid class.
Accordingly, it is necessary to add the oxycodone monograph in the Model Formulary in
accordance to the aforementioned Guidelines.
With this application, we request:
1. Addition of oxycodone preparations as an example of the opioid class to the EMLc.1
2. Addition of a monograph on oxycodone in the WHO Formulary for children
This application is part of a series of three applications:
- Application to add certain morphine formulations to the Essential Medicines List for
Children;
- Application to add oxycodone to the Essential Medicines List for Children; and
- Application to add hydromorphone to the Essential Medicines List for Children.
1 Two or more alternatives to morphine should be available and this should be expressed in the EMLc,
for example as a footnote to the square box.

Formulations proposed for inclusion, including a proposal for a monograph in the WHO Model Formulary for children
Preparations to be added to the EMLc
In order to provide adequate pain treatment for persisting pain in children, it is
required that the following formulations of oxycodone be added to the Essential Medicine
List for Children, under section 2.2 Opioid Analgesics:
a. Tablet: 5 mg, 10 mg, 15 mg, 20 mg, 30 mg (as hydrochloride)
b. Tablet (slow-release): 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 60 mg, 80
mg,160 mg (as hydrochloride)
c. Capsule: 5 mg, 10 mg, 20 mg (as hydrochloride)
d. Oral liquid: 1 mg/ml, 10 mg/ml, 20 mg/ml (as hydrochloride)
These preparations should be equally added to the palliative care section of the EMLc.
Rationale for these strengths and dosage forms
Introduction
The WHO Guidelines on the Pharmacological Treatment of Persisting Pain in
Children with Medical Illnesses identify four key concepts for the correct use of analgesic
medicines and three of these concepts affect the need and selection for oxycodone
preparations [Guidelines, 2012: pages 38–40]:
• dosing at regular intervals (“by the clock”)
• using the appropriate route of administration (“by the mouth”)
• tailoring treatment to the individual child (“by the individual”).
The WHO Guidelines on the Pharmacological Treatment of Persisting Pain in
Children strongly recommend switching opioids (and/or route of administration) in children
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances

in the presence of inadequate analgesic effect with intolerable side-effects. [Guidelines, 2012:
Guidelines 10, p. 44] and alternative opioids and/or dosage forms as an alternative to oral
morphine should be available to practitioners, in addition to morphine, if possible.
[Guidelines, 2012: Guidelines 11, p. 44; both slow-release and immediate-release
preparations should be available [Guidelines, 2012: Guideline 8, p. 43; Guideline 9, p. 43 ];
and oral administration of opioids is the recommended route of administration. [Guidelines,
2012: Guideline 13, p. 45]. Therefore, the availability of a full range of preparations is
essential.
Need for a range of strengths of immediate release tablets or capsules
To obtain a dose that provides adequate relief of pain with an acceptable degree of side-
effects the doses of oxycodone or other strong opioids need to be gradually increased until
effective. Unlike paracetamol and NSAIDs, there is no upper dosage limit for opioid
analgesics because there is no "ceiling" analgesic effect. The appropriate dose is the dose that
produces pain relief for the individual child. The goal of titration to pain relief is to select a
dose that prevents the child from experiencing pain between two doses using the lowest
effective dose. This is best achieved by frequent assessment of the child’s pain relief
response and adjusting the analgesic doses as necessary.
The opioid dose that effectively relieves pain varies widely between children, and in the
same child at different times, and should, therefore, be based on the child's pain severity
assessment. Large opioid doses given at frequent intervals may be necessary to control pain in
some children; these doses may be regarded as appropriate, provided that the side-effects are
minimal or can be managed with other medicines. Therefore, a range of strengths of
oxycodone, as an example of an alternative to morphine, should be added to the EMLc.
[WHO guidelines, p.47]
Need for slow release formulations
Access to multiple strengths of slow-release oxycodone is essential for the treatment of
moderate to severe persisting pain in children as slow-release morphine allow for longer dose
intervals, and this improves the patient’s compliance by reducing dose frequency.
Need for liquid formulations
The oral administration is the preferred route of administration. Older children may be
able to swallow regular or slow-release oxycodone tablets/capsules, but young children and
infants may only be able to use liquid formulations of oxycodone.
Relation to the application for hydromorphone
For patients who do not react well to morphine, the guidelines require that two or more
alternatives to morphine are available. While morphine has a very wide range of preparations
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
6
for both oral and parenteral administration and for immediate-release and slow-release, this is
not the case for all other strong opioids. Therefore, oxycodon and hydromorphone were
selected as together they have a wider range of administration forms readily available:
injections, tablets, slow-release tablets, capsules and oral liquid are all covered by this
selection.
Why other strong opioids from the guidelines are not selected to serve as the example of a the
class of strong opioids alternative to morphine
Fentanyl: fentanyl may be expensive in some countries and lozenges may be suitable
for breakthrough pain, but less suitable for titrating. Therefore, the range of dosage forms as a
whole may be less suitable than for oxycodone and hydromorphone.
Methadone: the long half-life of methadone makes it more difficult to dose.
International availability - sources, manufacturers and trade names Oxycodone hydrochloride as a starting material is out of patent. Oxycodon tablets, slow-
release tablets, capsules, injections, oral solution and concentrate for oral solution are
available for purchase in a number of countries.

Whether listing is requested as an individual medicine or as an example of a
therapeutic group Listing is requested as an example of a therapeutic group. According to the
Guidelines, “alternative opioids” (i.e. two or more alternatives) to morphine should be
available and this should be expressed in the EMLc, for example as a footnote to the square
box. [Guidelines, 2012: p. 44] The footnote could read “Examples for alternative opioids for
morphine. Two or more alternatives should be available in addition to morphine.”
Information supporting the public health relevance From a public-health perspective, currently many patients are without access to
essential medicines for pain. WHO policies recommend, and international drug conventions
require that countries make medicines controlled under these conventions readily available to
those in need. Opioid analgesics like morphine, hydrocodone and oxycodone are among these
controlled medicines.
The World Health Organization has a policy to promote the availability of strong
opioids in countries whose policies or legislation unduly does not allow access or availability
to strong opioids [Ensuring Balance, p.5]. Inclusion in the EMLc is essential for enhancing
this policy.
It has been well documented that in most countries of the world, patients do not have
adequate access to opioid analgesics. The various barriers are described in the World
Medicines Report [Milani B and Scholten W, 2011] and in the WHO policy guidelines
Ensuring Balance in National Policies on Controlled Substances, Accessibility and
Availability of Controlled Medicines. [Ensuring balance, 2011: p.5] Legal and policy barriers
are important reasons why these medicines are not available in many countries. Seya et al.
estimate that in 2006 only 464 million people had adequate access to opioid analgesics, and
4.7 billion people had virtually no access [Seya et al, 2011].
The World Health Assembly in its resolution 58.22 “On Cancer prevention and
control” (2005), called on WHO to address access to opioid analgesics [Resolution WHA
58.22, 2005]. Other international bodies such as the International Narcotics Control Board
(e.g. in a special report on the availability of internationally controlled drugs) [Report of the
INCB, 2011] and the UN Commission on Narcotic Drugs, have called for greater access for
patients to these medicines.
In addition, the International Association for the Study of Pain adopted the
Declaration of Montreal, the Union for International Cancer Control published the World
Cancer Declaration and a consortium of 60 international and national organizations initiated
by Pallium India launched the Morphine Manifesto. [Declaration of Montreal, 2011; World
Cancer Declaration, 2006; a Morphine Manifesto, 2012] All these declarations call for
adequate access to pain medicines and treatment of pain worldwide.

Treatment details The treatment recommended by the World Health Organization is published in the
WHO Guidelines on the Pharmacological Treatment of Persisting Pain in Children with
Medical Illnesses. These guidelines address the pharmacological management of persisting
pain in children with medical illnesses. As such, they replace the previous guidelines, Cancer
pain relief and palliative care in children, which exclusively covered cancer pain. [Guidelines,
2012: p. 10]. Treatment details in this application are based on the Guidelines on the
Pharmacological Treatment of Persisting Pain in Children.
For the treatment of pain, no special diagnostics are needed, nor any technical
monitoring facilities. Although in certain stages of treatment monitoring of the patient is
necessary, this refers to clinical monitoring which could include phone calls or home visits to
check on progress, dose tracking, or pulse oximetry and respiratory monitoring in hospital,
depending on circumstances. In (very) rare circumstances it might include urine drug testing.
The treatment of pain requires to be preceded by and go together with a regular
assessment of the pain with simple pain scales, such as the FPS-R scales. Methods are
described in Chapter 2, Evaluation of persisting pain in the paediatric population, of the
guidelines. [Guidelines, 2012: p. 26-35]
Treatment recommendations
Dosage:
Starting dose for opioid-naive patients:
Oral (immediate-release formulation):
infant 1–12 months – 50–125 mcg/kg every 4 hours;
child 1–12 years – 125–200 mcg/kg every 4 hours, max 5 mg.
Oral (slow-release formulation):
child over 8 years – 5 mg every 12 hours.
Continuation: after a starting dose according to the dosages above, the dosage should be
adjusted to the level that is effective (with no maximum), but the maximum dosage
increase is 50% per 24 hours in outpatient settings. Experienced prescribers can
increase up to 100% with careful monitoring of the patient.
Dose for breakthrough pain
Oral (using immediate-release preparation):
infant or child: Additional oxycodone may be administered as frequently as
required with a maximum of 5–10% of the regular daily baseline oxycodone dose.
If repeated breakthrough doses are required, adjust the regular baseline
oxycodone dose guided by the amount of oxycodone required for breakthrough
pain with a maximum increase of 50% per 24 hours.
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances

The WHO guidelines on the pharmacological treatment of persisting pain in children
are evidenced based guidelines, produced using the methods prescribed actually for WHO
treatment guidelines. Oxycodone is considered an example of a strong opioid, as an alternative to
morphine, for moderate to severe persisting pain in children. Two or more alternatives to morphine
should be available and this should be expressed in the EMLc, for example as a footnote to the square
box.
According to the WHO guidelines on the pharmacological treatment of persisting pain
in children with medical illnesses, the immediate release oxycodone is initially dosed at 50–
125 mcg/kg every 4 hours for infants aged 1–12 months, and 125–200 mcg/kg every 4 hours
(max 5 mg) for children aged 1 – 12 years. The oral slow-release formulation is dosed 5 mg
every 12 hours for children over 8 years of age. After the appropriate starting dose, the
dosage should be adjusted on an individual basis to the level that it is effective (with no
maximum dose, unless further increase is not possible because of untreatable side-effects).
The maximum dosage increase is 50% per 24 hours in outpatient settings. Experienced
prescribers can increase up to 100% while monitoring the patient carefully. Common adverse
effects of oxycodone include nausea, vomiting, constipation, lightheadedness, drowsiness,
dizziness, sedation, sweating, dysphoria, euphoria, dry mouth, anorexia, spasm of urinary and
biliary tract, pruritus, rash, sweating, palpitation, bradycardia, postural hypotension, and
miosis. Uncommon adverse effects include respiratory depression (dose-related), tachycardia,
and palpitations. Rare adverse effects include syndrome of inappropriate anti-diuretic
hormone secretion (SIADH) and anaphylaxis. However, if titrated correctly, most side effects
can be avoided.
Opioid weaning can be done safely without posing significant health risk to the
patient. From the medical standpoint, weaning opioids should be done slowly by tapering the
opioid dose. For short-term therapy (7–14 days), the original dose can be decreased by 10–
20% of the original dose every 8 hours, increasing gradually the time interval. In the case of a
long-term therapy protocol, the dose should be reduced not more than 10-20% per week.
These pharmacological approaches should be accompanied by measurement of withdrawal
symptoms using a scoring system [WHO guidelines, 2012: p.47].
The Guidelines Development Group on the WHO guidelines on the pharmacological
treatment of persisting pain in children considered the lack of instruction on how to titrate and
how to wean patients on opioids a hazard. Therefore this information is considered essential
for the Formulary monograph. There is a need for comparative trials of opioids in terms of
effectiveness, side-effects and feasibility of use in children with persisting pain due to medical
illnesses.
It should be mentioned that the initial dosage is lower than often recommended
elsewhere [British National Formulary for Children, 2011: p. 256; Scholten W, 2012]. The
experts considered dosages recommended elsewhere as not deprived of risk. Also the lack of
instruction on how to titrate and how to wean patients on opioids is considered a hazard.

Therefore this information is considered essential for the Formulary monograph. There is a
need for comparative trials of opioids in terms of effectiveness, side-effects and feasibility of
use in children with persisting pain due to medical illnesses.
Summary of comparative effectiveness in a variety of clinical settings The guidelines provide the evidence for its recommendations in a number of GRADE
tables [WHO guidelines, 2012: p.104 ] and the further justification for each recommendation
is provided in an annex [WHO guidelines, 2012: p.82]. The guidelines also concluded that
more research is needed in order to answer specific questions. The guidelines are based on the
best knowledge currently available. See Annex 1 and 2 of the application for detailed
information regarding the recommendations in the guidelines. Annex 1 contains GRADE
tables regarding oxycodone and Annex 2 contains background information for the
recommendations. (Please also refer to the GRADE Tables in the parallel applications on
morphine and hydrocodone preparations.)
For clinical data please refer to Annexes 1 and 2.
Summary of comparative evidence on safety 1. Estimate of total patient exposure to date Oxycodon has been used as an analgesic since 1939. Since, it has been used in
innumerous patients and it has been shown to be a safe medicine if used correctly. In 2006 the
world used 42.6 tonnes oxycodone, corresponding to 568 million DDDs. [Seya et al.,
unpublished data] The annual consumption by country can be roughly derived from the status
of estimates as published by the International Narcotics Control Board at
http://www.incb.org/incb/narcotic_drugs_estimates.html.
2. Description of adverse effects/reactions Adverse effects:
common – nausea, vomiting, constipation, dry mouth, sedation, biliary spasm,
respiratory depression, muscle rigidity, apnoea, myoclonic movements, asthenia,
dizziness, confusion, dysphoria, euphoria, lightheadedness, pruritus, rash,
somnolence, sweating;
uncommon – hypotension, hypertension, bradycardia, tachycardia, palpitation,
oedema, postural hypotension, miosis, visual disturbances, abdominal cramps,
anorexia, paraesthesia, malaise, agitation, tremor, muscle weakness,
hallucinations, vertigo, mood changes, dependence, drowsiness, anxiety, sleep
disturbances, headache, taste disturbance, agitation, urinary retention,
laryngospasm, bronchospasm;
rare – circulatory depression, cardiac arrest, respiratory arrest, shock, paralytic
ileus, seizures.
Interactions with other medicines:
central nervous system depressants – additive or potentiating effects with
hydromorphone;

ethanol* – additive or potentiating effects with hydromorphone, potential fatal
interaction (dose dumping) if used with extended-release hydromorphone
preparations;
monoamine oxidase inhibitors* – severe and unpredictable potentiation of
opioids;
naloxone* – precipitates opioid withdrawal symptoms;
naltrexone* – precipitates opioid withdrawal symptoms;
opioid antagonists/partial agonists* – may precipitate opioid withdrawal
symptoms.
* Indicates severe.
3. Identification of variation in safety due to health systems and patient factors Inter-individual differences exist. Like for other opioid analgesics, the dosage level for
oxycodone needs to be established on an individual base [WHO guidelines, 2012: p. 37],
guided by the outcome of regular pain assessment. Provided that oxycodone is prescribed
when indicated, and titrated and weaned according to the guidelines, it has shown to be a safe
medicine.
Development of dependence on medical treatment is not well documented and it is
assumed that the risk is very limited [Noble, 2008; Minozzi, submitted] and this risk is not a
reason not to treat when indicated.[Minozzi, submitted] On theoretical grounds, it is likely
that pain patients are less susceptible to opioid dependence than other people. [Niikura, 2010]
There are well-described problems with over-prescribing and diversion in a limited
number of countries, although these studies are related to prescription to adults and not to
children. Non-medical use carries substantial risks, including overdose and mortality. It
should be noted that the extensively reported increase in consumption in the United States has
been accompanied by a notable increase in overdose deaths involving prescription opioids
[CDC,2011; CDC, 2012]. While there are insufficient data available to quantify the amounts
diverted to non-medical use from various parts of the drug distribution system, it appears
there is significant theft, fraud and other unlawful conduct [Inciardi JA et al. 2006a; Inciardi
JA et al., 2006b]. A national population-based survey in the United States found that over
70% of those who have reported using opioids non-medically admitted that they obtained the
drug for free from friends or family members or through theft or purchase [SAMSHA, 2011].
Large quantities of prescription opioids have been sold by illegitimate pain clinics and
overdose has occurred predominantly in persons obtaining opioids from non-medical sources
[CDC, 2011]. In a study of unintentional overdose fatalities in West Virginia, 63.1% of the
decedents had used pharmaceuticals with no documented prescriptions, and 55.6% of the
decedents were never prescribed opioid analgesics. In addition, 79.3% of the decedents has
used multiple substances, both illicit and prescription drugs (“polydrug use”), which might
have contributed to their death, and 21.4 % of the decedents had controlled medicines
prescribed by multiple physicians (“doctor shopping”) [Hall AJ et al., 2008]. This study did
not determine, however, whether decedents from the latter group were ‘real’ pain pat ients, or
people seeking drugs for illicit purposes. Another American study, describing 9940 cases of
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
19
overdose deaths, found 51 cases to whom dosages of 100 mg/day or higher of morphine
equivalents were prescribed during the first three months of a prescription episode, showing
an increased risk for this group [Dunn KM et al., 2010].
In conclusion, although there is no doubt that some, albeit unknown, level of opioid
agonist prescribing and dispensing to pain patients contributes to morbidity and mortality in
the USA, many if not most of these tragedies appear to involve opioids that have been
diverted or obtained through unlawful activities, including those of non-patients.
4. Summary of comparative safety against comparators Opioids are the only class of medicines effective for moderate and severe pain, and
therefore, there are no comparators outside the class. Within the class of opioid analgesics,
there are no outspoken differences in safety with the exception of methadone, because of its
kinetics.
Summary of available data on comparative cost and cost-effectiveness
within the pharmacological class or therapeutic group 1. Range of costs of the proposed medicine The cost of slow release tablets 20 mg tablets in Switzerland ranges from Sfr 2.19 - 2.56
per tablet (USD 2.36 – 2.74 ); for all SR tablet strengths the range is Sfr 2.84 – 8.51 (USD
3.25 – 9.11) per 30 mg oxycodon. The cost of immediate release capsules 5mg ranges from
Sfr 0,80 - 1,14 per capsule (USD 0.85 – 1.22); for all strengths of the capsules the cost ranges
from Sfr 2.53 – 6.86 (USD 2.71 – 7.35) per 30 mg oxycodon. 30ml oral solution 1mg/ml costs
in Switzerland Sfr 44,30 (USD 47.45), which is Sfr 4.43 (USD 4.74) per 30 mg oxycodone.6

2. Comparative cost-effectiveness presented as range of cost per routine There is no standard dosage for oxycodone for adult patients and therefore it is even more
difficult to define a standard dosage for a child. Foley et al. found that the average terminal
cancer patient needs 75 mg morphine a day during the last three months of his or her life.
[Foley, 2006] This corresponds with a dosage of approximately 30 mg oxycodone per day
orally for the treatment of a ten year old child with comparable pain.
The cost of one day of treatment (30 mg) for this child are presented above for the various
preparations available in Switzerland and the Netherlands. For all dosage forms and strengths,
the price range for 30 mg of oxycodone is Sfr 0.80 – 8.51 (US$ 0.85 – 9.11) for Switzerland.
In the Netherlands, the cost of one day of treatment (30 mg) for this child ranges for all
strengths of immediate release tablets from € 1.77 to € 2.10 (US$ 2.29 - 2.72) per 30 mg, for
all strengths of slow-release tablets from € 1.17 to € 2.34 (US$ 1.51 - 3.03) per 30 mg, for all
strengths of capsules from € 2.04 to € 8.22 (US$ 2.64 - 10.63) per 30 mg and for the oral
liquid it is € 20.40 (US $ 26.39) per 30 mg. The overall range is from € 1.17 to € 20.40 (US$
1.51 – 26.39).
As the Swiss price level for medicines is known to be high, the Swiss prices should be
regarded as the upper end of the price range. Among European countries, the Netherlands has
relatively low medicines prices.
Summary of regulatory status of the medicine in several countries Oxycodone was introduced as an analgesic in Germany in 1939. Currently, it is on the
market in Germany, the Netherlands, Switzerland, the United States of America and many
other countries.
Oxycodone is subject to international control under the Single Convention on Narcotic
Drugs, 1961. For enabling good access in all countries, the World Health Organization
published the policy guidelines Ensuring Balance in National Policies on Controlled
Substances, guidance for availability and accessibility of controlled medicines in 2011
[Ensuring Balance, p.4].

Availability of pharmacopoeial standards (British Pharmacopoeia,
International Pharmacopoeia, United States Pharmacopoeia) The International Pharmacopoeia, the British Pharmacopoeia and the Unites States
Pharmacopoeia all contain monographs for oxycodone hydrochloride. [The International
Pharmacopoeia, 2011, CD-version; British Pharmacopoeia, 2012, p. 10916; United States
Pharmacopoeia, online version accessed 14 September 2012].
In addition, the United States Pharmacopoeia has monographs on Oxycodone
Hydrochloride oral solution, Oxycodone Hydrochloride Tablets and Oxycodone
Hydrochloride Extended Tablets. [United States Pharmacopoeia, online version accessed 14
September 2012].
Proposed new text for the WHO Model Formulary The publication of the WHO Guidelines on the pharmacological treatment of persisting pain
in children entails also a pharmaceutical profile on oxycodone, following the monograph format of the
WHO Formulary for children. The profile contains updated dosage schedules and instruction for
titrating the patient to adequate pain management and for weaning opioids. A proposed text is
provided below. 7

prolonged treatment; diabetes mellitus; impaired consciousness; acute pancreatitis;
myasthenia gravis; hepatic impairment; renal impairment; toxic psychosis.
Skilled tasks: warn the patient or caregiver about the risk of undertaking tasks
requiring attention or coordination, for example, riding a bike.
Dosage:
Starting dose for opioid-naive patients:
Oral (immediate-release formulation):
infant 1–12 months – 50–125 mcg/kg every 4 hours;
child 1–12 years – 125–200 mcg/kg every 4 hours, max 5 mg. Oral (slow-release formulation):
child over 8 years – 5 mg every 12 hours.
Continuation: after a starting dose according to the dosages above, the dosage should be
adjusted to the level that is effective (with no maximum), but the maximum dosage
increase is 50% per 24 hours in outpatient settings. Experienced prescribers can
increase up to 100% with careful monitoring of the patient.
Dose for breakthrough pain
Oral (using immediate-release preparation):
infant or child: Additional oxycodone may be administered as frequently as
required with a maximum of 5–10% of the regular daily baseline oxycodone
dose. If repeated breakthrough doses are required, adjust the regular baseline
oxycodone dose guided by the amount of oxycodone required for breakthrough
pain with a maximum increase of 50% per 24 hours.
Dosage discontinuation: for short-term therapy (7–14 days), the original dose can be
decreased by 10–20% of the original dose every 8 hours increasing gradually the time
interval. In the case of a long-term therapy protocol, the dose should be reduced not
more than 10–20% per week (79,80).
Renal impairment: mild (GRF 20–50 ml/min or approximate serum creatinine 150–300
micromol/l) to severe (GFR <10ml/min or serum creatinine > 700 micromol/l) – dose
reduction may be required; start with lowest dose and titrate according to response.
Hepatic impairment: moderate and severe; reduce dose by 50% or avoid use.
Adverse effects:
common – nausea, vomiting, constipation, diarrhoea, dry mouth, sedation, biliary
spasm, abdominal pain, anorexia, dyspepsia, pruritus, somnolence, dizziness;

bronchospasm, dyspnoea, impaired cough reflex, asthenia, anxiety, chills, muscle
fasciculation, postural hypotension, hallucinations, vertigo, euphoria, dysphoria,
dizziness, confusion;
uncommon – bradycardia, tachycardia, palpitation, oedema, mood changes,
dependence, drowsiness, sleep disturbances, headache, miosis, visual
disturbances, sweating, flushing, rash, urticaria, restlessness, difficulty with
micturition, urinary retention, ureteric spasm, gastritis, flatulence, dysphagia,
taste disturbance, belching, hiccups, vasodilation, supraventricular tachycardia,
syncope, amnesia, hypoasthesia, pyrexia, amenorrhoea, hypotonia, paraesthesia,
disorientation, malaise, agitation, speech disorder, tremor, dry skin;
rare – raised intracranial pressure, circulatory depression, cardiac arrest,
respiratory arrest, shock, paralytic ileus, seizures.
Interactions with other medicines:
central nervous system depressants – additive or potentiating effects with
oxycodone;
monoamine oxidase inhibitors* – severe and unpredictable potentiation of
opioids;
naloxone* – precipitates opioid withdrawal symptoms;
naltrexone* – precipitates opioid withdrawal symptoms;
opioid antagonists/partial agonists* – may precipitate opioid withdrawal
symptoms.
* Indicates severe.
Notes:
Oxycodone is subject to international control under the Single Convention on Narcotic
Drugs, 1961.
Slow-release oxycodone preparations must not be crushed or chewed; the child must
be able to swallow the whole tablet.
Administer with food to reduce gastrointestinal upset.
Oxycodone is partially metabolized to an active metabolite, oxymorphone, via
CYP2D6 pathway; slow or ultra-fast metabolizers may experience reduced or
enhanced analgesia and dose-related side-effects.
High strength slow-release tablets should only be used in patients who are opioid
tolerant. Administration of these strengths to non-opioid tolerant patients may cause
fatal respiratory depression.
Naloxone is used as an antidote in case of opioid overdose.
Equianalgesic doses:
When converting from oral morphine to oral oxycodone, use an initial dose conversion ratio
of 1.5:1 (e.g. replace 15 mg morphine with 10 mg oxycodone). Then titrate to optimize the
analgesia.

A2.2.3 Strong opioids essential in pain treatment
Clinical question
In children with persisting pain due to medical illnesses, what are the benefits as compared to the risks
(hastening death, developing dependence, respiratory depression, influencing the child's development)
of taking regular or intermittent morphine for pain control as compared with a similar group of
patients with persisting pain not taking any opioid analgesics?
Recommendation
4. The use of strong opioid analgesics is recommended for the relief of moderate to severe
persisting pain in children with medical illnesses.
Strong recommendation, low quality of evidence
Domains and considerations
Quality of evidence
Although, no systematic reviews or randomized control trials were retrieved to guide determination of
the balance between the benefits and disadvantages of the use of strong opioids in children, the panel
considered indirect evidence from adult chronic non-cancer pain (71).
The panel noted the following statement, which supported the inclusion of morphine in the 2010
EMLc: “Morphine is the strong opioid of choice in moderate to severe pain in children and this is
confirmed by a number of consensus guidelines. There is extensive clinical experience of its use in
children and its use should be promoted to ensure adequate analgesia as necessary” (72).
Uncertainty: none.
Risks/benefits
Benefits
The efficacy of strong opioids in the relief of pain is well accepted. The panel noted, however, that
studies comparing opioids are possible in this age group provided that acceptable and appropriate trial
methodology is used.
Risks
Risks associated with severe side-effects and mortality arising from medication errors were considered
manageable, although more data on long-term use in children are necessary.
Uncertainty: none
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
28
Values and acceptability
In favour
The panel valued access to effective treatment of pain in children.
Against
None
Uncertainty: none.
Cost
Although access to strong opioids is variable, price is not generally a significant barrier for a number
of strong opioids.
Uncertainty: none.
Feasibility
Access to strong opioids for medical use remains a challenge worldwide. However, the rational use of
opioid analgesics in countries with limited financial and human resources is feasible and
recommended.
Uncertainty: none.
Policy agenda
Countries should review, and if necessary, revise their policies and regulations to ensure availability
and accessibility of opioid analgesics for the relief of moderate to severe pain in children as provided
for in the preamble of the Single Convention on Narcotic Drugs, 1961.
A2.2.4 Choice of strong opioids
Clinical question
In children with persisting pain due to medical illnesses, what is the evidence to support the use of
morphine as a gold standard for strong opioids as compared to the use of other strong opioids (in
particular fentanyl, hydromorphone, oxycodone and methadone) in order to achieve rapid, effective
and safe pain control?
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances

Recommendations
5. Morphine is recommended as the first-line strong opioid for the treatment of persisting
moderate to severe pain in children with medical illnesses.
6. There is insufficient evidence to recommend any alternative opioid in preference to
morphine as the opioid of first choice.
7. Selection of alternative opioid analgesics to morphine should be guided by considerations
of safety, availability, cost and suitability, including patient-related factors.
Strong recommendations, low quality of evidence
Domains and considerations
Quality of evidence
The panel noted that morphine has been available for a considerable amount of time and that high
quality of evidence is unlikely to be available. The second recommendation was based on comparisons
between different opioids and routes of administration in acute pain and post-operative pain in
children. (Annex 4. Evidence retrieval and appraisal, GRADE tables 2–4, 6, 7). The assessed level of
quality of evidence was downgraded because of the differences in conditions treated and duration of
treatment.
Uncertainty: yes.
Risks/benefits
Benefits
Morphine is well established as first-line strong opioid.
Risks
Risks are well described and considered to be manageable.
Uncertainty: no, for the use of morphine as a first-line opioid analgesic; yes, in relation to the
comparative safety and efficacy of different opioids.
Values and acceptability
In favour
The panel valued access to effective treatment.
Against
None
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
30
Uncertainty: none.
Cost
Morphine is relatively inexpensive, although prolonged-release oral solid forms are more costly.
Uncertainty: none.
Feasibility
A wide range of morphine formulations have been already included in the 2010 EMLc:
granules, slow-release (to mix with water) – 20 mg, 30 mg, 60 mg, 100 mg, 200 mg
injection – 10 mg (morphine hydrochloride or morphine sulfate) in 1 ml ampoule
oral liquid – 10 mg (morphine hydrochloride or morphine sulfate)/5 ml
tablet – 10 mg (morphine sulfate)
tablet (prolonged release) – 10 mg, 30 mg, 60 mg, 100 mg, 200 mg (morphine sulfate).
Uncertainty: none.
Research agenda
Comparative trials of strong opioids, including fentanyl, hydromorphone, oxycodone and methadone,
in the treatment of persisting moderate to severe pain in children of all ages with medical illnesses are
needed. They should investigate effectiveness, side-effects and feasibility of use in this population.
Child appropriate oral solid dosage forms are needed.
A2.2.5 Prolonged-release versus immediate-release morphine
Clinical question
In children with persisting pain due to medical illnesses, should prolonged-release morphine be used
in preference to immediate-release morphine to achieve and maintain effective and safe pain control?
Recommendations
8. It is strongly recommended that immediate-release oral morphine formulations be available
for the treatment of persistent pain in children with medical illnesses.
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
31
9. It is also recommended that child-appropriate prolonged-release oral dosage forms be
available, if affordable.
Strong recommendations, low quality of evidence
Domains and considerations
Quality of evidence
There is insufficient evidence to support the use of prolonged-release over immediate-release
morphine as a sole agent. The only available evidence is in adults (Annex 4. Evidence retrieval and
appraisal, GRADE Table 10). The Cochrane review found that, in spite of the relevance of this
comparison, only 15 studies of 460 participants compared prolonged-release morphine preparations
with immediate-release morphine (115). None of the trials were large, having a median size of 27
participants (age range: 16–73). The results of these trials show that immediate-release and slow-
release morphine formulations are equivalent for pain relief. Approximately 6% of participants
(adults) in the studies who received morphine (any type) experienced intolerable adverse effects.
Uncertainty: yes, in relation to children since no studies are available in this age group.
Risks/benefits
Benefits
Immediate-release oral morphine needs to be administered more frequently, but it is always necessary
in the management of episodic or breakthrough pain.
Risks
Adherence to long-term treatment with immediate-release oral morphine may be problematic.
Uncertainty: none.
Values and acceptability
In favour
The panel valued access to immediate-release oral morphine and noted that commercially marketed
prolonged-release oral morphine formulations are sometimes the only products available for
procurement.
Against
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
32
None
Uncertainty: none.
Cost
Immediate-release oral morphine is relatively inexpensive but may not be commercially available in
all countries. Morphine powder for extemporaneous preparation may be available, but requires access
to pharmacists and suitable diluents, and its compounding may be subject to legal restrictions. The
stability of such preparations needs to be investigated.
Uncertainty: none.
Feasibility
No problem of feasibility, rather affordability for prolonged-release morphine formulation.
Uncertainty: none.
Research agenda
Research into appropriate formulations for the extemporaneous preparation of oral liquid morphine is
needed. Dissemination of available evidence on the preparation of stable extemporaneous formulations
is encouraged.
A2.2.6 Opioid rotation and opioid switching
Clinical question
In children with persisting pain due to medical illnesses, what is the evidence to support opioid
rotation policies to prevent dose escalation and side-effects?
Recommendations
10. Switching opioids and/or route of administration in children is strongly recommended in
the presence of inadequate analgesic effect with intolerable side-effects.
11. Alternative opioids and/or dosage forms as an alternative to oral morphine should be
available to practitioners, in addition to morphine, if possible.
12. Routine rotation of opioids is not recommended.
Strong recommendations, low quality of evidence
Domains and considerations
Quality of evidence
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
33
No systematic reviews or randomized control trials were found in children. A Cochrane Review
exclusively looked for and found no RCTs on opioid switching or rotation in adults and children.
Identified case reports, uncontrolled and retrospective studies were examined in order to determine the
current level of evidence (116). The review concluded that although for patients suffering chronic
cancer pain opioid switching may be the only option for enhancing pain relief and minimizing opioid
toxicity, there is a current lack of an evidence base for this therapeutic strategy. A systematic review
published in 2006 (117), identified one retrospective study of opioid switching in 22 children with
cancer pain. This review described a positive response to switching in patients intolerant to a particular
opioid, but noted that RCTs are lacking and that the observations were based on uncontrolled data.
Uncertainty: yes, in relation to the potential utility of rotation policies; no, in relation to switching of
opioid and/or route of administration in the presence of inadequate effect or intolerable side-effects.
Risks/benefits
Benefits
The panel placed a high value on effective use of adequate doses of the chosen opioid.
Risks
Risks are well described and considered to be manageable. Access to age-appropriate dose conversion
table for different opioids is necessary for safe switching.
Uncertainty: none.
Values and acceptability
In favour
The panel placed high value on treating rather than not treating pain and providing an alternative when
response is inadequate and side-effects are intolerable.
Against
None
Uncertainty: none.
Cost
Alternative opioids to morphine might be more expensive. However, there are regional variations in
costs and some alternatives to morphine may even be cheaper.
Uncertainty: none.
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
34
Feasibility
Access to an age-appropriate dose conversion table for different opioids is necessary for safe
switching.
Uncertainty: yes.
Policy and research agenda
The panel requests an update of the 2004 Cochrane review on opioid switching, including data from
children, if available. Opioid rotation policies lend themselves to investigation by prospective trials.
Such research is encouraged. Research on dose conversion in different age groups is necessary.

Annex 2: application on hydromorphone of 21 September 2012, to the
19th Expert Committee on the Selection and Use of Essential Medicines
Application to add hydromorphone to the
Essential Medicines List for Children
Summary statement of the proposal for inclusion Pain in children is a public health concern of major significance in most parts of the world.
Although the means and knowledge to relieve pain exists, children’s pain is often not recognized, is
ignored, or even denied. It is important that adequate access to appropriate opioid medicines be
available for the treatment of moderate to severe persisting pain in children worldwide.
To align the Essential Medicine List for Children (EMLc) with the recently published WHO
guidelines on the pharmacological treatment of persisting pain in children with medical illnesses
[WHO pediatric pain guidelines, 2012: p.78– further referred to as “Guidelines”], it is necessary to add
more opioids to the EMLc. The Guidelines state that if pain severity associated with a medical illness
is assessed as moderate or severe, the administration of a strong opioid is necessary. In that case
morphine is the medicine of choice, although other strong opioids should be considered and made
available to ensure an alternative to morphine in case of intolerable side-effects. It is advised that two
or more strong opioids should be available for this purpose, and hydromorphone is one such strong
opioid. Thus, it is requested that hydromorphone be added to the EMLc as an example of the opioid
class. Accordingly, it is necessary to add the hydromorphone monograph in the Model Formulary in
accordance to the aforementioned Guidelines.
With this application, we request:
1. Addition of hydromorphone as an example of the opioid class to the EMLc8
2. Addition of a monograph on hydromorphone in the WHO Formulary for children
This application is part of a series of three applications:
- Application to add certain morphine formulations to the Essential Medicines List for Children;
8 Two or more alternatives to morphine should be available and this should be expressed in the EMLc, for
example as a footnote to the square box.

Formulations proposed for inclusion, including a proposal for a monograph in the WHO Model Formulary for children
Preparations to be added to the EMLc
In order to provide adequate pain treatment for persisting pain in children, it is required that
the following formulations of hydromorphone be added to the Essential Medicine List for Children,
under section 2.2 Opioid Analgesics:
a. Injection (as hydrochloride):
1 mg in 1 ml ampoule,
2 mg in 1 ml ampoule,
4 mg in 1 ml ampoule,
10 mg in 1 ml ampoule
b. Tablet: 2 mg, 4 mg, 8 mg (as hydrochloride).
c. Oral liquid: 1 mg (as hydrochloride)/ml.
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
40
These preparations should be equally added to the palliative care section of the EMLc.
Rationale for these strengths and dosage forms
Introduction
The WHO Guidelines on the Pharmacological Treatment of Persisting Pain in Children with
Medical Illnesses identify four key concepts for the correct use of analgesic medicines and three of
these concepts affect the need and selection for hydromorphone preparations [Guidelines, 2012: pages
38–40]:
• dosing at regular intervals (“by the clock”)
• using the appropriate route of administration (“by the mouth”)
• tailoring treatment to the individual child (“by the individual”).
In relation to this, the WHO Guidelines on the Pharmacological Treatment of Persisting Pain
in Children strongly recommend switching opioids (and/or route of administration) in children in
thepresence of inadequate analgesic effect with intolerable side-effects. [Guidelines, 2012: Guidelines
10, p. 44] and alternative opioids and/or dosage forms as an alternative to oral morphine should be
available to practitioners, in addition to morphine, if possible. [Guidelines, 2012: Guidelines 11, p. 44;
both slow-release and immediate-release preparations should be available [Guidelines, 2012:
Guideline 8, p. 43; Guideline 9, p. 43 ]; and oral administration of opioids is the recommended route
of administration. [Guidelines, 2012: Guideline 13, p. 45]. Therefore, the availability of a full range of
preparations is essential.
Need for a range of strengths of injections
The subcutaneous route (via continuous infusion or intermittent bolus through an indwelling
catheter) is widely used and could be a valuable alternative to oral dosages. It is essential that
hydromorphone, injection formulation, be available for the adequate treatment of persisting pain in
children. Hydromorphone, is more widely available for parenteral administration than oxycodone.
In addition to the more common or traditional ways of administering, patient-controlled
analgesia (PCA) is a possible approach to intravenous or subcutaneous administration. It allows
children from approximately the age of seven to self-administer "rescue" doses of analgesics for
breakthrough pain. A pre-set dose is delivered into an infusion line by a computer-driven pump. For
safety, there is a limited lock-out period after each dose so that additional doses cannot be delivered
before a specified time has elapsed. Patient-controlled analgesia may be used alone or with concurrent
continuous infusions. It should be noted that PCA techniques might require access to expensive
equipment.
Need for a range of strengths of immediate release tablets
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
41
To obtain a dose that provides adequate relief of pain with an acceptable degree of side-
effects the doses of hydrocodone or other strong opioids need to be gradually increased until
effective. Unlike paracetamol and NSAIDs, there is no upper dosage limit for opioid
analgesics because there is no "ceiling" analgesic effect. The appropriate dose is the dose that
produces pain relief for the individual child. The goal of titration to pain relief is to select a
dose that prevents the child from experiencing pain between two doses using the lowest
effective dose. This is best achieved by frequent assessment of the child’s pain relief
response and adjusting the analgesic doses as necessary.
The opioid dose that effectively relieves pain varies widely between children, and in the
same child at different times, and should, therefore, be based on the child's pain severity
assessment. Large opioid doses given at frequent intervals may be necessary to control pain in
some children; these doses may be regarded as appropriate, provided that the side-effects are
minimal or can be managed with other medicines. Therefore, a range of strengths of
hydromorphone, as an example of an alternative to morphine, should be added to the EMLc.
[WHO guidelines, p.47]
Need for liquid formulation
The oral administration is the preferred route of administration. Older children may be able to
swallow regular or slow-release oxycodone tablets/capsules, but young children and infants may only
be able to use liquid formulations of hydromorphone.
Relation to the application for oxycodone
For patients who do not react well to morphine, the guidelines require that two or more
alternatives to morphine are available. While morphine has a very wide range of preparations
for both oral and parenteral administration and for immediate-release and slow-release, this is
not the case for all other strong opioids. Therefore, oxycodon and hydromorphone were
selected as together they have a wider range of administration forms readily available:
injections, tablets, slow-release tablets, capsules and oral liquid are all covered by this
selection.
Why other strong opioids from the guidelines are not selected to serve as the example of a the
class of strong opioids alternative to morphine
Fentanyl: fentanyl may be expensive in some countries and lozenges may be suitable
for breakthrough pain, but less suitable for titrating. Therefore, the range of dosage forms as a
whole may be less suitable than for oxycodone and hydromorphone.
Methadone: the long half-life of methadone makes it more difficult to dose.

Whether listing is requested as an individual medicine or as an
example of a therapeutic group
Listing is requested as an example of a therapeutic group. According to the Guidelines,
“alternative opioids” (i.e. two or more alternatives) to morphine should be available and this should be
expressed in the EMLc, for example as a footnote to the square box. [Guidelines, 2012: p. 44] The
footnote could read “Examples for alternative opioids for morphine. Two or more alternatives should
be available in addition to morphine.”
Information supporting the public health relevance
From a public-health perspective, currently many patients are without access to essential
medicines for pain. WHO policies recommend, and international drug conventions require, that
countries make medicines controlled under these conventions readily available to those in need.
Opioid analgesics like morphine, hydrocodone and oxycodone are among these controlled medicines.
The World Health Organization has a policy to promote the availability of strong opioids in
countries whose policies or legislation unduly does not allow access or availability to strong opioids
[Ensuring balance, p.5]. Inclusion in the EMLc is essential for enhancing this policy.
It has been well documented that in most countries of the world, patients do not have adequate
access to opioid analgesics. The various barriers are described in the World Medicines Report [Milani
B and Scholten W, 2011] and in the WHO policy guidelines Ensuring Balance in National Policies
on Controlled Substances, Accessibility and Availability of Controlled Medicines. [Ensuring balance,
2011: p.5] Legal and policy barriers are important reasons why these medicines are not available in
many countries. Seya et al. estimate that in 2006 only 464 million people had adequate access to
opioid analgesics, and 4.7 billion people had virtually no access [Seya et al, 2011].
The World Health Assembly in its resolution 58.22 “On Cancer prevention and control”
(2005), called on WHO to address access to opioid analgesics [Resolution WHA 58.22, 2005]. Other
international bodies such as the International Narcotics Control Board (e.g. in a special report on the
availability of internationally controlled drugs) [Report of the INCB, 2011] and the UN Commission
on Narcotic Drugs, have called for greater access for patients to these medicines.
In addition, the International Association for the Study of Pain adopted the Declaration of
Montreal, the Union for International Cancer Control published the World Cancer Declaration and a
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
45
consortium of 60 international and national organizations initiated by Pallium India launched the
Morphine Manifesto. [Declaration of Montreal, 2011; World Cancer Declaration, 2006; a Morphine
Manifesto, 2012] All these declarations call for adequate access to pain medicines and treatment of
pain worldwide.
Treatment
The treatment recommended by the World Health Organization is published in the WHO
Guidelines on the Pharmacological Treatment of Persisting Pain in Children with Medical Illnesses.
These guidelines address the pharmacological management of persisting pain in children with medical
illnesses. As such, they replace the previous guidelines, Cancer pain relief and palliative care in
children, which exclusively covered cancer pain. [Guidelines, 2012: p. 10]. Treatment details in this
application are based on the Guidelines on the Pharmacological Treatment of Persisting Pain in
Children.
For the treatment of pain, no special diagnostics are needed, nor any technical monitoring
facilities. Although in certain stages of treatment monitoring of the patient is necessary, this refers to
clinical monitoring which could include phone calls or home visits to check on progress, dose
tracking, or pulse oximetry and respiratory monitoring in hospital, depending on circumstances. In
(very) rare circumstances it might include urine drug testing.
The treatment of pain requires to be preceded by and go together with a regular assessment of
the pain with simple pain scales, such as the FPS-R scales. Methods are described in Chapter 2,
Evaluation of persisting pain in the paediatric population, of the guidelines. [Guidelines, 2012: p. 26-
35]
Treatment recommendations
Dosage:
Starting dose for opioid-naive patients:
Oral (using immediate-release formulations):
child – initially 30 – 80 mcg/kg per dose (maximum 2 mg per dose) every 3–4
hours.
Subcutaneous or intravenous:
child – initially 15 mcg/kg per dose slowly over at least 2–3 minutes every 3–6
hours.
Continuation: after a starting dose according to the dosages above, the dosage
should be adjusted to the level that is effective (with no maximum), but the
maximum dosage increase is 50% per 24 hours in outpatient settings. Experienced
prescribers can increase up to 100% with close monitoring of the patient.
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances

The WHO guidelines on the pharmacological treatment of persisting pain in children are
evidenced based guidelines, produced using the methods prescribed actually for WHO treatment
guidelines. Hydromorphone is considered an example of a strong opioid, as an alternative to
morphine, for moderate to severe persisting pain in children. Two or more alternatives to morphine
should be available and this should be expressed in the EMLc, for example as a footnote to the square
box.
The guidelines provide the evidence for its recommendations in a number of GRADE tables
[WHO guidelines, 2012: p.104 ] and the further justification for each recommendation is provided in
an annex [WHO guidelines, 2012: p.82]. The guidelines also concluded that more research is needed
in order to answer specific questions. The guidelines are based on the best knowledge currently
available. See Annex 1 and 2 of the application for detailed information regarding the
recommendations in the guidelines. Annex 1 contains GRADE tables regarding morphine and Annex
2 contains background information for the recommendations. (Please also refer to the GRADE Tables
in the parallel applications on morphine and oxycodone preparations.)
According to the WHO guidelines on the pharmacological treatment of persisting pain in
children with medical illnesses, the oral formulation of hydromorphone is initially dosed at 30-80
mcg/kg every 3-4 hours for children. The subcutaneous or intravenous formulation of hydromorphone
is initially dosed at 15 mcg/kg over at least 2-3 minutes every 3-6 hours in children. After the
appropriate starting dose, the dosage should be adjusted on an individual basis to the level that it is
effective (with no maximum dose, unless further increase is not possible because of untreatable side-
effects). The maximum dosage increase is 50% per 24 hours in outpatient settings. Experienced
prescribers can increase up to 100% while monitoring the patient carefully. Common adverse effects
of hydromorphone include nausea, vomiting, constipation, dry mouth, sedation, biliary spasm,
respiratory depression, muscle rigidity, apnoea, myoclonic movements, asthenia, dizziness, confusion,
dysphoria, euphoria, lightheadedness, pruritus, rash, somnolence, and sweating. Uncommon adverse
effects include hypotension, hypertension, bradycardia, tachycardia, palpitation, oedema, postural
hypotension, miosis, visual disturbances, abdominal cramps, anorexia, paraesthesia, malaise, agitation,
tremor, muscle weakness, hallucinations, vertigo, mood changes, dependence, drowsiness, anxiety,
sleep disturbances, headache, taste disturbance, agitation, urinary retention, laryngospasm, and
bronchospasm. Rare adverse effects include circulatory depression, cardiac arrest, respiratory arrest,
shock, paralytic ileus, and seizures. However, if titrated correctly, most side effects can be avoided.
Opioid weaning can be done safely without posing significant health risk to the patient. From
the medical standpoint, weaning opioids should be done slowly by tapering the opioid dose. For short-
term therapy (7–14 days), the original dose can be decreased by 10–20% of the original dose every 8
hours, increasing gradually the time interval. In the case of a long-term therapy protocol, the dose
should be reduced not more than 10-20% per week. These pharmacological approaches should be
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
47
accompanied by measurement of withdrawal symptoms using a scoring system [WHO guidelines,
p.47].
The Guidelines Development Group on the WHO guidelines on the pharmacological
treatment of persisting pain in children considered the lack of instruction on how to titrate and how to
wean patients on opioids is considered a hazard. [Scholten W, 2012 ] Therefore this information is
considered essential for the Formulary monograph. There is a need for comparative trials of opioids in
terms of effectiveness, side-effects and feasibility of use in children with persisting pain due to
medical illnesses. Hydromorphone is considered an example of a strong opioid choice, as an
alternative to morphine, for moderate to severe persisting pain in children. Two or more alternatives
to morphine should be available and this should be expressed in the EMLc, for example as a footnote
to the square box.
The experts considered dosages recommended elsewhere as not deprived of risk. Also the
lack of instruction on how to titrate and how to wean patients on opioids is considered a hazard.
Therefore this information is considered essential for the Formulary monograph. There is a need for
comparative trials of opioids in terms of effectiveness, side-effects and feasibility of use in children
with persisting pain due to medical illnesses.
Summary of comparative effectiveness in a variety of clinical settings
The guidelines provide the evidence for its recommendations in a number of GRADE tables
[WHO guidelines, 2012: p.104 ] and the further justification for each recommendation is provided in
an annex [WHO guidelines, 2012: p.82]. The guidelines also concluded that more research is needed
in order to answer specific questions. The guidelines are based on the best knowledge currently
available. See Annex 1 and 2 of the application for detailed information regarding the
recommendations in the guidelines. Annex 1 contains GRADE tables regarding morphine and Annex
2 contains background information for the recommendations. (Please also refer to the GRADE Tables
in the parallel applications on morphine and oxycodone preparations.)
For clinical data please refer to Annexes 1 and 2.
Summary of comparative evidence on safety
5. Estimate of total patient exposure to date Hydromorphone has been used as an analgesic since 1926. Since, it has been used in innumerous
patients and it has been shown to be a safe medicine if used correctly. In 2006 the world used 10.2
tonnes hydrocodone or 510 million DDDs. [Seya et al., unpublished data] The annual consumption by
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
48
country can be roughly derived from the status of estimates as published by the International Narcotics
Control Board at http://www.incb.org/incb/narcotic_drugs_estimates.html.
6. Description of adverse effects/reactions Adverse effects:
common – nausea, vomiting, constipation, dry mouth, sedation, biliary spasm,
respiratory depression, muscle rigidity, apnoea, myoclonic movements, asthenia,
dizziness, confusion, dysphoria, euphoria, lightheadedness, pruritus, rash,
somnolence, sweating;
uncommon – hypotension, hypertension, bradycardia, tachycardia, palpitation,
oedema, postural hypotension, miosis, visual disturbances, abdominal cramps,
anorexia, paraesthesia, malaise, agitation, tremor, muscle weakness,
hallucinations, vertigo, mood changes, dependence, drowsiness, anxiety, sleep
disturbances, headache, taste disturbance, agitation, urinary retention,
laryngospasm, bronchospasm;
rare – circulatory depression, cardiac arrest, respiratory arrest, shock, paralytic
ileus, seizures.
Interactions with other medicines:
central nervous system depressants – additive or potentiating effects with
hydromorphone;
ethanol* – additive or potentiating effects with hydromorphone, potential fatal
interaction (dose dumping) if used with extended-release hydromorphone
preparations;
monoamine oxidase inhibitors* – severe and unpredictable potentiation of
opioids;
naloxone* – precipitates opioid withdrawal symptoms;
naltrexone* – precipitates opioid withdrawal symptoms;
opioid antagonists/partial agonists* – may precipitate opioid withdrawal
symptoms.
* Indicates severe.
7. Identification of variation in safety due to health systems and patient factors Inter-individual differences exist. Like for other opioid analgesics, the dosage level for
hydrocodone needs to be established on an individual base [WHO guidelines, 2012: p. 37], guided by
the outcome of regular pain assessment. Provided that hydrocodone is prescribed when indicated, and
titrated and weaned according to the guidelines, it has shown to be a safe medicine.
Development of dependence on medical treatment is not well documented and it is assumed that
the risk is very limited [Noble, 2008; Minozzi, submitted] and this risk is not a reason not to treat
when indicated.[Minozzi, submitted] On theoretical grounds, it is likely that pain patients are less
susceptible to opioid dependence than other people. [Niikura, 2010]
There are well-described problems with over-prescribing and diversion in a limited number of
countries, although these studies are related to prescription to adults and not to children. Non-medical
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
49
use carries substantial risks, including overdose and mortality. It should be noted that the extensively
reported increase in consumption in the United States has been accompanied by a notable increase in
overdose deaths involving prescription opioids [CDC,2011; CDC, 2012]. While there are insufficient
data available to quantify the amounts diverted to non-medical use from various parts of the drug
distribution system, it appears there is significant theft, fraud and other unlawful conduct [Inciardi JA
et al. 2006a; Inciardi JA et al., 2006
b]. A national population-based survey in the United States found
that over 70% of those who have reported using opioids non-medically admitted that they obtained the
drug for free from friends or family members or through theft or purchase [SAMSHA, 2011]. Large
quantities of prescription opioids have been sold by illegitimate pain clinics and overdose has occurred
predominantly in persons obtaining opioids from non-medical sources [CDC, 2011]. In a study of
unintentional overdose fatalities in West Virginia, 63.1% of the decedents had used pharmaceuticals
with no documented prescriptions, and 55.6% of the decedents were never prescribed opioid
analgesics. In addition, 79.3% of the decedents has used multiple substances, both illicit and
prescription drugs (“polydrug use”), which might have contributed to their death, and 21.4 % of the
decedents had controlled medicines prescribed by multiple physicians (“doctor shopping”) [Hall AJ et
al., 2008]. This study did not determine, however, whether decedents from the latter group were ‘real’
pain patients, or people seeking drugs for illicit purposes. Another American study, describing 9940
cases of overdose deaths, found 51 cases to whom dosages of 100 mg/day or higher of morphine
equivalents were prescribed during the first three months of a prescription episode, showing an
increased risk for this group [Dunn KM et al., 2010].
In conclusion, although there is no doubt that some, albeit unknown, level of opioid agonist
prescribing and dispensing to pain patients contributes to morbidity and mortality in the USA, many if
not most of these tragedies appear to involve opioids that have been diverted or obtained through
unlawful activities, including those of non-patients.
8. Summary of comparative safety against comparators Opioids are the only class of medicines effective for moderate and severe pain, and therefore,
there are no comparators outside the class. Within the class of opioid analgesics, there are no
outspoken differences in safety with the exception of methadone, because of its kinetics.
Summary of available data on comparative cost and cost-effectiveness
within the pharmacological class or therapeutic group
3. Range of costs of the proposed medicine The cost of 1 ampoule of 2mg/ml, 1 ml is € 1.93 (US$ 2.49); that of an ampoule 10mg/ml, 1ml is
€ 9.67 (US$ 12.51) in the Netherlands. The cost of 50ml oral solution 1mg/ml is in Switzerland Sfr
34,50 (USD 36.95).13

4. Comparative cost-effectiveness presented as range of cost per routine outcome (e.g. cost per case, cost per cure, cost per month of treatment, cost per case prevented, cost per clinical event prevented, or, if possible and relevant, cost per quality adjusted life year gained)
There is no standard dosage for hydromorphone for adult patients and therefore it is even more
difficult to define a standard dosage for a child. The wide variability of prices around the world further
confuses the picture. Foley et al. found that the average terminal cancer patient needs 75 mg morphine
a day during the last three months of his or her life. [Foley, 2006] This corresponds with a dosage of
approximately 5 mg hydromorphone per day orally (or 2.5 mg per day parenterally) for the treatment
of a ten year old child with comparable pain.
If treated with oral solution at the price in Switzerland, one day of treatment costs US$ 3.96; if
treated parenterally, at the Dutch price level, the daily cost ranges from US$ 2.99-3.15.
As the Swiss price level for medicines is known to be high, the Swiss prices should be regarded as
the upper end of the price range. Among European countries, the Netherlands has relatively low
medicines prices.
Summary of regulatory status of the medicine in several countries Hydrocodone was first marketed in Germany in 1926. Currently, it is on the market in Germany,
the Netherlands, the United States of America and many other countries, but often in limited ranges of
dosage forms and strengths.
Hydrocodone is subject to international control under the Single Convention on Narcotic Drugs,
1961. For enabling good access in all countries, the World Health Organization published the policy
guidelines Ensuring Balance in National Policies on Controlled Substances, guidance for availability
and accessibility of controlled medicines in 2011 [Ensuring Balance, p.4].

naltrexone* – precipitates opioid withdrawal symptoms;
opioid antagonists/partial agonists* – may precipitate opioid withdrawal
symptoms.
* Indicates severe.
Notes:
Hydromorphone is subject to international control under the Single Convention on
Narcotic Drugs, 1961.
Hydromorphone is a potent opioid and significant differences exist between oral and
intravenous dosing. Use extreme caution when converting from one route to another.
Give with food or milk to decrease gastrointestinal upset.
Extended-release preparations are available; however, these are not indicated for use
in the paediatric setting.
Naloxone is used as an antidote in case of opioid overdose.
Equianalgesic doses:
Hydromorphone - morphine vice versa
According to manufacturers, oral hydromorphone is 7.5 times more potent than
morphine; however, when switching from morphine to hydromorphone, some suggest
the ratio is 5:1 (i.e. the dose of hydromorphone should be 1/5 of the morphine dose), and
when switching from hydromorphone to morphine a ratio of 1:4 should be used (i.e. the
morphine dose should be 4 times the hydromorphone dose).
Parenteral hydromorphone to oral hydromorphone
If switching from parenteral to oral hydromorphone, oral doses are less than one-half as
effective as parenteral doses (may only be 1/5 as effective). Doses may need to be titrated
up to 5 times the IV dose.

A2.2.3 Strong opioids essential in pain treatment
Clinical question
In children with persisting pain due to medical illnesses, what are the benefits as compared to the risks
(hastening death, developing dependence, respiratory depression, influencing the child's development)
of taking regular or intermittent morphine for pain control as compared with a similar group of
patients with persisting pain not taking any opioid analgesics?
Recommendation
4. The use of strong opioid analgesics is recommended for the relief of moderate to severe
persisting pain in children with medical illnesses.
Strong recommendation, low quality of evidence
Domains and considerations
Quality of evidence
Although, no systematic reviews or randomized control trials were retrieved to guide determination of
the balance between the benefits and disadvantages of the use of strong opioids in children, the panel
considered indirect evidence from adult chronic non-cancer pain (71).
The panel noted the following statement, which supported the inclusion of morphine in the 2010
EMLc: “Morphine is the strong opioid of choice in moderate to severe pain in children and this is
confirmed by a number of consensus guidelines. There is extensive clinical experience of its use in
children and its use should be promoted to ensure adequate analgesia as necessary” (72).
Uncertainty: none.
Risks/benefits
Benefits
The efficacy of strong opioids in the relief of pain is well accepted. The panel noted, however, that
studies comparing opioids are possible in this age group provided that acceptable and appropriate trial
methodology is used.
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
58
Risks
Risks associated with severe side-effects and mortality arising from medication errors were considered
manageable, although more data on long-term use in children are necessary.
Uncertainty: none
Values and acceptability
In favour
The panel valued access to effective treatment of pain in children.
Against
None
Uncertainty: none.
Cost
Although access to strong opioids is variable, price is not generally a significant barrier for a number
of strong opioids.
Uncertainty: none.
Feasibility
Access to strong opioids for medical use remains a challenge worldwide. However, the rational use of
opioid analgesics in countries with limited financial and human resources is feasible and
recommended.
Uncertainty: none.
Policy agenda
Countries should review, and if necessary, revise their policies and regulations to ensure availability
and accessibility of opioid analgesics for the relief of moderate to severe pain in children as provided
for in the preamble of the Single Convention on Narcotic Drugs, 1961.

A2.2.4 Choice of strong opioids
Clinical question
In children with persisting pain due to medical illnesses, what is the evidence to support the use of
morphine as a gold standard for strong opioids as compared to the use of other strong opioids (in
particular fentanyl, hydromophone, oxycodone and methadone) in order to achieve rapid, effective and
safe pain control?
Recommendations
5. Morphine is recommended as the first-line strong opioid for the treatment of persisting
moderate to severe pain in children with medical illnesses.
6. There is insufficient evidence to recommend any alternative opioid in preference to
morphine as the opioid of first choice.
7. Selection of alternative opioid analgesics to morphine should be guided by considerations
of safety, availability, cost and suitability, including patient-related factors.
Strong recommendations, low quality of evidence
Domains and considerations
Quality of evidence
The panel noted that morphine has been available for a considerable amount of time and that high
quality of evidence is unlikely to be available. The second recommendation was based on comparisons
between different opioids and routes of administration in acute pain and post-operative pain in
children. (Annex 4. Evidence retrieval and appraisal, GRADE tables 2–4, 6, 7). The assessed level of
quality of evidence was downgraded because of the differences in conditions treated and duration of
treatment.
Uncertainty: yes.
Risks/benefits
Benefits
Morphine is well established as first-line strong opioid.
Risks
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
60
Risks are well described and considered to be manageable.
Uncertainty: no, for the use of morphine as a first-line opioid analgesic; yes, in relation to the
comparative safety and efficacy of different opioids.
Values and acceptability
In favour
The panel valued access to effective treatment.
Against
None
Uncertainty: none.
Cost
Morphine is relatively inexpensive, although prolonged-release oral solid forms are more costly.
Uncertainty: none.
Feasibility
A wide range of morphine formulations have been already included in the 2010 EMLc:
granules, modified release (to mix with water) – 20 mg, 30 mg, 60 mg, 100 mg, 200 mg
injection – 10 mg (morphine hydrochloride or morphine sulfate) in 1 ml ampoule
oral liquid – 10 mg (morphine hydrochloride or morphine sulfate)/5 ml
tablet – 10 mg (morphine sulfate)
tablet (prolonged release) – 10 mg, 30 mg, 60 mg, 100 mg, 200 mg (morphine sulfate).
Uncertainty: none.
Research agenda
Comparative trials of strong opioids, including fentanyl, hydromorphone, and methadone, in the
treatment of persisting moderate to severe pain in children of all ages with medical illnesses are
needed. They should investigate effectiveness, side-effects and feasibility of use in this population.
Willem Scholten PharmD MPA Consultant – Medicines and Controlled Substances
61
Child appropriate oral solid dosage forms are needed.
A2.2.5 Prolonged-release versus immediate-release morphine
Clinical question
In children with persisting pain due to medical illnesses, should prolonged-release morphine be used
in preference to immediate-release morphine to achieve and maintain effective and safe pain control?
Recommendations
8. It is strongly recommended that immediate-release oral morphine formulations be available
for the treatment of persistent pain in children with medical illnesses.
9. It is also recommended that child-appropriate prolonged-release oral dosage forms be
available, if affordable.
Strong recommendations, low quality of evidence
Domains and considerations
Quality of evidence
There is insufficient evidence to support the use of prolonged-release over immediate-release
morphine as a sole agent. The only available evidence is in adults (Annex 4. Evidence retrieval and
appraisal, GRADE Table 10). The Cochrane review found that, in spite of the relevance of this
comparison, only 15 studies of 460 participants compared prolonged-release morphine preparations
with immediate-release morphine (115). None of the trials were large, having a median size of 27
participants (age range: 16–73). The results of these trials show that immediate-release and modified-
release morphine formulations are equivalent for pain relief. Approximately 6% of participants
(adults) in the studies who received morphine (any type) experienced intolerable adverse effects.
Uncertainty: yes, in relation to children since no studies are available in this age group.
Risks/benefits
Benefits
Immediate-release oral morphine needs to be administered more frequently, but it is always necessary
in the management of episodic or breakthrough pain.
Risks

62
Adherence to long-term treatment with immediate-release oral morphine may be problematic.
Uncertainty: none.
Values and acceptability
In favour
The panel valued access to immediate-release oral morphine and noted that commercially marketed
prolonged-release oral morphine formulations are sometimes the only products available for
procurement.
Against
None
Uncertainty: none.
Cost
Immediate-release oral morphine is relatively inexpensive but may not be commercially available in
all countries. Morphine powder for extemporaneous preparation may be available, but requires access
to pharmacists and suitable diluents, and its compounding may be subject to legal restrictions. The
stability of such preparations needs to be investigated.
Uncertainty: none.
Feasibility
No problem of feasibility, rather affordability for prolonged-release morphine formulation.
Uncertainty: none.
Research agenda
Research into appropriate formulations for the extemporaneous preparation of oral liquid morphine is
needed. Dissemination of available evidence on the preparation of stable extemporaneous formulations
is encouraged.
A2.2.6 Opioid rotation and opioid switching

Clinical question
In children with persisting pain due to medical illnesses, what is the evidence to support opioid
rotation policies to prevent dose escalation and side-effects?
Recommendations
10. Switching opioids and/or route of administration in children is strongly recommended in
the presence of inadequate analgesic effect with intolerable side-effects.
11. Alternative opioids and/or dosage forms as an alternative to oral morphine should be
available to practitioners, in addition to morphine, if possible.
12. Routine rotation of opioids is not recommended.
Strong recommendations, low quality of evidence
Domains and considerations
Quality of evidence
No systematic reviews or randomized control trials were found in children. A Cochrane Review
exclusively looked for and found no RCTs on opioid switching or rotation in adults and children.
Identified case reports, uncontrolled and retrospective studies were examined in order to determine the
current level of evidence (116). The review concluded that although for patients suffering chronic
cancer pain opioid switching may be the only option for enhancing pain relief and minimizing opioid
toxicity, there is a current lack of an evidence base for this therapeutic strategy. A systematic review
published in 2006 (117), identified one retrospective study of opioid switching in 22 children with
cancer pain. This review described a positive response to switching in patients intolerant to a particular
opioid, but noted that RCTs are lacking and that the observations were based on uncontrolled data.
Uncertainty: yes, in relation to the potential utility of rotation policies; no, in relation to switching of
opioid and/or route of administration in the presence of inadequate effect or intolerable side-effects.
Risks/benefits
Benefits
The panel placed a high value on effective use of adequate doses of the chosen opioid.
Risks
Risks are well described and considered to be manageable. Access to age-appropriate dose conversion
table for different opioids is necessary for safe switching.

Uncertainty: none.
Values and acceptability
In favour
The panel placed high value on treating rather than not treating pain and providing an alternative when
response is inadequate and side-effects are intolerable.
Against
None
Uncertainty: none.
Cost
Alternative opioids to morphine might be more expensive. However, there are regional variations in
costs and some alternatives to morphine may even be cheaper.
Uncertainty: none.
Feasibility
Access to an age-appropriate dose conversion table for different opioids is necessary for safe
switching.
Uncertainty: yes.
Policy and research agenda
The panel requests an update of the 2004 Cochrane review on opioid switching, including data from
children, if available. Opioid rotation policies lend themselves to investigation by prospective trials.
Such research is encouraged. Research on dose conversion in different age groups is necessary.
