Role of regulatory authorities in quality control of
pharmaceuticals
1. Pharmaceutical quality control
The Quality Control department of the PC Pharmaceuticals comprises coordinated
activities for quality control of all the entered and raw materials, thru the manufacturing
process until the production of final product with specified shelf life in appropriate storage
conditions and specification compliant to the strictest European and International standards.
The Quality Control is consisted of several coordinated activities.
1.1 Control of the raw materials, contact and secondary packaging
The control of the active pharmaceutical ingredients, the other compounds and the
contact packaging includes activities for control of their physical and chemical properties and
microbiological characteristics in accordance with the European and internationally
recognized standards. The secondary packaging should provide sufficient and understandable
information to the medical personnel and patients. These activities are performed using
modern validated instruments and techniques such as: infrared spectroscopy with narrow
identification area for each container of incoming raw-material, infrared spectroscopy, total
organic carbon analyzers that analyze the total organic carbon in the water as a medium for
pharmaceutical production, gas chromatography and high performance liquid
chromatography, automatic titration measuring devices, etc.
1.2 Control of the phase production and control of final products
The products are monitored in all the phases of their manufacturing, with all their
specifics by phase, until the final product is delivered which, from the aspect of physical,
chemical and pharmaceutically-technological properties, corresponds to the specifications set
forth by the strictest international regulations.
The activities are performed by employing modern validated instruments such as:
high performance liquid chromatographs, spectrophotometers connected in line to dissolution
equipment and etc.
The analytical methods used for the analysis are continuously upgraded and
modernized and accordingly validated resulting in highest level of safety and confidence of
their performances.
1.3 Microbiological control
This controlling part operates within the new microbiological laboratory constructed
in compliance with the most sophisticated cGMP norms.
In the microbiologically classified areas appropriate equipment has been installed
such as: bio-safety laminar cabinets for analysis performance, incubators, dry sterilizers,
autoclaves, coolers/freezers, microscopes, Vitek II instrument for microorganism's
identification etc. The following activities are carried out by applying coordinated and strictly
determined procedures: control of the products and systems, control of purified water and
other media for pharmaceutical manufacturing, supervision of the premises and equipment
hygiene in the manufacturing facilities as well as all other activities in compliance with the
DPP standards.
As part of the biological tests, the tests for absence of bacterial endotoxins are
performed by modern kinetic turbidimetric methods onto the entry raw materials and the
finished product that are specific for sterile production.
1.4 Stability of the pharmaceutical finished products
Samples from the commercially produced batches are stored in special stability rooms
in conditions that simulate the worst case of outdoor conditions at which the products are
exposed during their lifecycle until the declared expiry date. In determined plans, reanalysis
are performed by which the declared expiry date and the specified storage conditions of the
products are proven to be in accordance to the previously defined specification.
1.5 Validation activities and monitoring
In the frames of the GMP operations, the following analysis are implemented related
to: validation of the analytical methods, validation of the production processes, cleaning
validation of the premises and equipment, validation of the water systems for pharmaceutical
application, compressed air, steam, cleanness of the equipment etc. With previously defined
scheme of critical points in previously defined time frames the routine monitoring of all
defined activities is continuously performed.
The quality inputs of raw materials for manufacturing together with the other
controlled conditions for pharmaceutical production are preconditions for providing of safe
and high quality final product.
1.6 Registration activities
The Quality Control department works on development of the analytical part of the
documentation required for the registration files of the products, which are integral part of the
internationally recognized CTD registration format for pharmaceutical products.
2. Regulatory authorities
A regulatory authority (also regulatory agency, regulatory body or regulator) is
a public authority or government agency responsible for exercising autonomous authority
over some area of human activity in a regulatory or supervisory capacity. An independent
regulatory agency is a regulatory agency that is independent from other branches or arms of
the government.
Regulatory authorities deal in the area of administrative law, regulation
or rulemaking (codifying and enforcing rules and regulations and imposing supervision or
oversight for the benefit of the public at large). The existence of independent regulatory
agencies is justified by the complexity of certain regulatory and supervisory tasks that require
expertise, the need for rapid implementation of public authority in certain sectors, and the
drawbacks of political interference. Some independent regulatory agencies perform
investigations or audits, and some are authorized to fine the relevant parties and order certain
measures.
Regulatory authorities are usually a part of the executive branch of the government, or
they have statutory authority to perform their functions with oversight from the legislative
branch. Their actions are generally open to legal review. Regulatory authorities are
commonly set up to enforce standards and safety, or to oversee use of public goods and
regulate commerce. Examples of regulatory agencies are the Interstate Commerce
Commission and U.S. Food and Drug Administration in the United States, Ofcom in
the United Kingdom, and the TRAI in India.
3. Principles for drug regulatory authorities
Regulation is not the only component of pharmaceutical policy, and sometimes in
resource-limited settings, it is not even the most pressing one. Nonetheless, the existence of a
well-functioning national drug regulatory authority to help ensure medicine quality, safety
and efficacy is the best guarantee that the public is getting the medicines it deserves. A
national regulatory authority needs a clear mission statement including goals and objectives
to direct its work. Goals usually include protecting public health by ensuring the safety,
efficacy, and quality of medicines and their appropriate use. Plainly outlined objectives
provide a measure to evaluate how well the agency is functioning.
Primary pharmaceutical regulation activities should not be compromised by other
non-regulatory tasks with which the national regulatory authority may be charged. If the
authority responsible for pharmaceutical regulation has non-regulatory functions, such as
manufacturing, procurement, or service delivery, conflicts of interest may occur regarding
mandates and resource allocation.
When a country is ready to introduce pharmaceutical regulation, work by WHO
(1990) provides useful guidance for authorities with limited human, financial, scientific, and
technological resources. To be effective, a small drug regulatory authority needs to operate
within the national pharmaceutical laws and policies that have been established and must
relate to other interested bodies, including organizations responsible for pharmaceutical
procurement in public sector and the national formulary committee. As mentioned,
effectively enforcing pharmaceutical legislation requires national regulatory authorities and
other government enforcement agencies, such as customs, police, and prosecutor, to work
together. National regulatory agencies should also seek the cooperation of health
professionals, pharmaceutical and consumer associations, and other interested parties through
stakeholder workshops, meetings addressing specific issues, or other venues open to the
public.
A drug regulatory authority’s objectives can be accomplished effectively only if a
mandatory system of licensing products, manufacture, importing agents, and distributors is in
place. A small authority has limited capacity to undertake these tasks. For imported
pharmaceutical substances, a small authority is dependent on information generated in the
exporting country.
The World Health Organization (WHO) certification scheme on the quality of
pharmaceutical products moving in international commerce (WHO 2000) was designed to
provide this information, although recommendations have been made on how to update the
scheme (WHO 2008). This scheme must be supplemented by direct contacts with
international agencies and other regulatory agencies to obtain necessary information.
However, the certification scheme is only as good as the certifying authority. WHO’s
prequalification program provides information on approved sources for products related to
HIV/AIDS, malaria, tuberculosis, and reproductive health.
Many national regulatory authorities do not make publicly available their regulatory
policies, administrative procedures, guidelines, and criteria for decisions. Lack of
transparency means that communication is probably lacking on medicine regulation between
national regulatory authorities and their stakeholders.
Moreover, transparency is required to make the agency accountable for its actions and
to limit the influence of political pressures and personal favors in the decision-making
process. Transparency will also contribute to the credibility and authority of communications
between the agency and those affected by its actions: manufacturers, importers, distributors,
health professionals, and consumers. An assessment tool is available to measure transparency
in the pharmaceutical sectors (WHO 2009a) and a report describes the assessment of four
countries’ pharmaceutical registration, selection and procurement systems: Malaysia,
Phillipines, and Thailand.
To increase the amount of information and communication, WHO is helping drug
regulatory authorities develop websites with information on:
Lists of approved medicines
National pharmaceutical regulations
Methods to ensure safe, efficacious, and rational use of specific medicines
List of approved companies and their authorized activities
Details of persons and institution with responsibility for pharmaceutical regulation
4. International Conference on Harmonisation of Technical Requirements
for Registration of Pharmaceuticals for Human Use (ICH)
The International Conference on Harmonisation of Technical Requirements for
Registration of Pharmaceuticals for Human Use (ICH) is a project that brings together the
regulatory authorities of Europe, Japan and the United States and experts from
the pharmaceutical industry in the three regions to discuss scientific and technical aspects of
pharmaceutical product registration.
The purpose of ICH is to reduce or obviate the need to duplicate the testing carried
out during the research and development of new medicines by recommending ways to
achieve greater harmonisation in the interpretation and application of technical guidelines and
requirements for product registration. Harmonisation would lead to a more economical use of
human, animal and material resources, and the elimination of unnecessary delay in the global
development and availability of new medicines while maintaining safeguards on quality,
safety, and efficacy, and regulatory obligations to protect public health.
ICH guidelines have been adopted as law in several countries, but are only used as
guidance for the U.S. Food and Drug Administration.
Since its inception in 1990, ICH has gradually evolved, to respond to the increasingly
global face of drug development, so that the benefits of international harmonisation for better
global health can be realised worldwide. ICH's mission is to achieve greater harmonisation to
ensure that safe, effective, and high quality medicines are developed and registered in the
most resource-efficient manner.
5. Role of regulatory authorities
To ensure that it does fill its role, a regulatory authorities uses mechanisms such as the
following
Transparency of information and decision-making
Procedures of consultation and participation
Requirement that administrators give reasons explaining their actions
Requirement that administrators follow principles that promote non-arbitrary and
responsive decisions.
Arrangements for review of administrative decisions by courts or other bodies
6. Regulation of therapeutic goods
The regulation of therapeutic goods, that is drugs and therapeutic devices, varies
by jurisdiction. In some countries, such as the United States, they are regulated at the national
level by a single agency. In other jurisdictions they are regulated at the statelevel, or at both
state and national levels by various bodies, as is the case in Australia.
The role of therapeutic goods regulation is designed mainly to protect the health and
safety of the population. Regulation is aimed at ensuring the safety, quality, and efficacy of
the therapeutic goods which are covered under the scope of the regulation. In most
jurisdictions, therapeutic goods must be registered before they are allowed to be marketed.
There is usually some degree of restriction of the availability of certain therapeutic goods
depending on their risk to consumers.
7. Pharmaceutical quality system
The term “pharmaceutical quality system” refers to the ICH Q10 model. ICH Q10
describes one comprehensive model for an effective pharmaceutical quality system that is
based on International Standards Organisation (ISO) quality concepts, includes applicable
Good Manufacturing Practice (GMP) regulations and complements ICH Q8 “Pharmaceutical
Development” and ICH Q9 “Quality Risk Management”.
ICH Q10 is a model for a pharmaceutical quality system that can be implemented
throughout the different stages of a product lifecycle. Much of the content of ICH Q10
applicable to manufacturing sites is currently specified by regional GMP requirements. ICH
Q10 is not intended to create any new expectations beyond current regulatory requirements.
Consequently, the content of ICH Q10 that is additional to current regional GMP
requirements is optional.
ICH Q10 demonstrates industry and regulatory authorities’ support of an effective
pharmaceutical quality system to enhance the quality and availability of medicines around the
world in the interest of public health. Implementation of ICH Q10 throughout the product
lifecycle should facilitate innovation and continual improvement and strengthen the link
between pharmaceutical development and manufacturing activities.
7.1 Scope of ICH
This guideline applies to the systems supporting the development and manufacture of
pharmaceutical drug substances (i.e., API) and drug products, including biotechnology and
biological products, throughout the product lifecycle.
The elements of ICH Q10 should be applied in a manner that is appropriate and
proportionate to each of the product lifecycle stages, recognising the differences among, and
the different goals of each stage.
For the purposes of this guideline, the product lifecycle includes the following
technical activities for new and existing products:
Pharmaceutical Development:
o Drug substance development
o Formulation development (including container/closure system)
o Manufacture of investigational products
o Delivery system development
o Manufacturing process development and scale-up
o Analytical method development
Technology Transfer:
o New product transfers during development through manufacturing
o Transfers within or between manufacturing and testing sites for marketed
products
Commercial Manufacturing:
o Acquisition and control of materials
o Provision of facilities, utilities, and equipment
o Production (including packaging and labelling)
o Quality control and assurance
o Release
o Storage
o Distribution (excluding wholesaler activities)
Product Discontinuation:
o Retention of documentation
o Sample retention
o Continued product assessment and reporting
7.2 Relationship of ICH Q10 to Regulatory Approaches
Regulatory approaches for a specific product or manufacturing facility should be
commensurate with the level of product and process understanding, the results of quality risk
management, and the effectiveness of the pharmaceutical quality system. When implemented,
the effectiveness of the pharmaceutical quality system can normally be evaluated during a
regulatory inspection at the manufacturing site. Potential opportunities to enhance science
and risk based regulatory approaches are identified. Regulatory processes will be determined
by region.
7.3 Objectives of ICH Q10
Implementation of the Q10 model should result in achievement of three main
objectives which complement or enhance regional GMP requirements.
a) Achieve Product Realisation
- To establish, implement and maintain a system that allows the delivery of
products with the quality attributes appropriate to meet the needs of patients,
health care professionals, regulatory authorities (including compliance with
approved regulatory filings) and other internal and external customers.
b) Establish and Maintain a State of Control
- To develop and use effective monitoring and control systems for process
performance and product quality, thereby providing assurance of continued
suitability and capability of processes. Quality risk management can be useful in
identifying the monitoring and control systems.
c) Facilitate Continual Improvement
- To identify and implement appropriate product quality improvements, process
improvements, variability reduction, innovations and pharmaceutical quality
system enhancements, thereby increasing the ability to fulfil quality needs
consistently. Quality risk management can be useful for identifying and
prioritising areas for continual improvement.
8. Role of pharmaceutical legislation and regulation
The role of pharmaceuticals has become more prominent on international agendas as
health indicators have been increasingly linked with a country’s successful development. In
addition, the legal and economic issues that surround pharmaceuticals have become more
complex and politicized because of the increase in global trade.
Because so many parties are involved with medicines, the laws need to clearly state
the roles, responsibilities, and rights of each, ranging from practitioners, auxiliaries, nurses,
and pharmacists to importers, manufacturers, and distributors. Countries approach prescribing
and dispensing differently, depending on their circumstances; for example, in Canada, a
physician must be the medicine prescriber, but in areas where physicians are scarce, legal
authority may be granted to nurses or other health practitioners to prescribe essential
medicines. The legislation should establish the qualifications required for those handling
medicines, or it must state who has the authority to set these standards by passing appropriate
regulations (for example, a government minister).
8.1 Licensing, inspection, and quality control
The law should create mechanism to ensure that relevant parties are licensed and
inspected so the community can have confidence in them. Doctors and nurses may be
covered by other laws, but the medicine law needs to ensure that people who import,
distribute, and sell medicines are properly qualified, approved, registered, and inspected.
Pharmaceuticals themselves require a special form of inspection. An inspector visiting
a pharmacy or warehouse may have reason to suspect that medicines are not of sufficient
quality or in good condition: they may be damp, dirty, or disintegrating. More often, samples
need to be obtained for testing in the quality-control laboratory, an essential part of the
inspection system.
Some countries have their own quality-control laboratories, either specifically for
medicines or shared with other commodities (such as foods). A number of countries use
regional laboratories, such as the ones serving sub-Saharan Africa or the Caribbean.
Whatever the structure, the pharmaceutical law needs to designate a quality-control
laboratory that has the capacity and equipment to do the job.
Countries that have pharmaceutical manufacturing operations should enforce good
manufacturing practices (GMP), which is a system to ensure that products are consistently
produced and controlled according to quality standards. GMP covers all aspects of production
from the starting materials, premises, equipment, and quality testing to the training and
personal hygiene of staff. WHO has established detailed guidelines for good manufacturing
practice, and many countries have formulated their own requirements based on WHO’s GMP.
Other regions, such as the Association of Southeast Asian Nations and the European Union,
have harmonized their GMP requirements.
Although important, GMP monitoring sometimes receives more resources than the
inspection of distribution channels; however, the consumer’s interest is not served by
manufacturing a product under GMP but then storing and distributing it under adverse
conditions. Inspection of distribution channels, including the importation of pharmaceuticals,
should also be emphasized, particularly in countries where the distribution system has several
intermediate levels or the climate is unfavorable. WHO has produced guidelines relating to
good storage practices for pharmaceuticals (WHO 2003a).
8.2 Pharmacovigilance
The law should also provide a basis for a pharmacovigilance (that is, post-marketing
surveillance) system to report problems with adverse reactions and product quality.
Pharmacovigilance is defined by WHO (2002a) as “the science and activities relating to the
detection, assessment, understanding and prevention of adverse effects or any other drug-
related problems”.
Pharmacovigilance is an overacting concept that encompassed any system used to
monitor medicine safety, use, and efficacy. For example, adverse drug reaction monitoring as
part of a product’s post-marketing surveillance contributes to the assessment of benefit,
effectiveness, and risk of medicines. A pharmacovigilance system is difficult if not possible
to implement in an unregulated market that allow the importation and sale of pharmaceuticals
which provides a clearinghouse for the millions of adverse drug reaction reports reveived
from almost 100 countries. International pharmacovigilance activities have had a notable
effect on international drug regulation.
8.3 Advertising and promotion
Although many countries have rules to ensure that advertising is not misleading, thses
rules are generally not sufficient to cover pharmaceuticals. With consumer products, a certain
degree of exaggeration is often tolerated as the normal practice of the marketplace. But for
medicines that have the capacity to kill or cure, and with claims that people cannot easily
verify, it is important that advertising to health professionals and to consumers be objective
and reliable; misleading and extravagant pharmaceutical advertising claims may pose
significant risks to the public.
For these reasons, most laws on pharmaceuticals now include a clause empowering
regulation on advertising. In many countries, it is illegal to advertise to consumers medicines
intended to be prescribed by health professionals. However, direct promotion of
pharmaceutical products through the internet is practically impossible to control; therefore,
the national regulatory agency should educate consumers on identifying reliable sources of
information, preferably in collaboration with national consumer and professional
organizations. All advertising and labeling must be consistent with the information verified
when the pharmaceutical product was registered or approved for marketing, with
modifications required by the regulatory authority on the basis of post-marketing experience.
8.4 Sanctions
Because constant vigilance is needed if the public is to be protected, pharmaceutical
laws must be properly enforced with appropriate penalties for violators. There is no use
establishing that medicine quality is poor, a warehouse is rat infested or damp upon
inspection, or an advertisement is untruthful unless something is done about it. The drug
regulatory agency must use its authority to impose appropriate penalties when necessary:
sanctions may be penal (fines, imprisonment, or both) or simply corrective (banning the drug,
closing down the warehouse). Sometimes a party has contravened the law so seriously that
the appropriate sanction is determined to be loss of license to prescribe, manufacture, import,
or distribute. On occasion, all of the penalties may be imposed.
To be effective, the drug regulatory authority must be able to apply sanctions on a
timely basis, so it must have either the legal staff to ensure compliance or the necessary links
with the relevant government department charged with enforcement. Therefore, the law
governing pharmaceutical products must give legal authority to the appropriate personnel to
carry out any necessary enforcement activities.
In addition, because the pharmaceutical sector is vulnerable to corruption, a country
should not only include an anticorruption mechanism in its regulatory framework, but also
have sanctions in place for bribery, fraud, collusion, and other dishonest acts (WHO/PSM
2006). Many countries have specific laws that address corruption in the public sector or
provisions in their procurement regulations to ensure transparency and provide sanctions
against, for example, bribery.
9. Evaluating the effectiveness of pharmaceutical legislation
Evaluating the effectiveness of pharmaceutical legislation and accompanying
regulations is not always easy. The process of evaluation depends on the types of
performance indicators and criteria used and on the availability of adequate data.
The most important factor in the effectiveness of pharmaceutical laws and regulations
is the extent to which the legislative framework is in tune with national policy and the
existing situation in the pharmaceutical sector. Changes in policy need to be reflected in the
legislation and in its implementation. Measuring the effectiveness of a law on
pharmaceuticals is easier for certain elements than for others. For instance, the registration
process can be evaluated in relation to quantitative targets and time schedules to see whether
the agency is on schedule.
The degree of non-compliance with a law or regulation may suggest not only the need
to take action against those responsible but also the desirability of identifying the causes of
non-compliance: it may be related to technical defects in the law or in its wording, or to
operational problems of implementation, such as lack of transparency or poor
communication, which can be resolved. Enforcement personnel should periodically report on
their perception of how the law functions and the types of problems encountered to facilitate
any necessary revisions. Many legislative and regulatory provisions can be improved and
updated when the legislation is sufficiently flexible to allow for modifications by the
regulatory agency.
Responsibility for evaluating the effectiveness of a drug law often falls on the
regulatory authority established by law for policy making, implementation, or both. The level
of accountability and transparency under which the drug regulatory authority operates can be
evaluated by examining reporting requirements, external reviews of performance, process
involved with lodging complaints, and appeals procedures. Periodic self-evaluation to
identify weaknesses in policy making and implementation activities is important. The body
must devise its own systems to judge whether it receives sufficient feedback and whether its
operational effectiveness can be improved.
10. Conclusion
Recommendations and guidelines provide an essential foundation for the development
and maintenance of quality assurance of pharmaceutical products. But it is personnel who are
crucial to quality assurance at all levels of pharmaceutical manufacture, regulation and
distribution.
Pharmacists have an important contribution to make in public health and particularly
in the field of medicines. WHO meetings on the role of the pharmacist in the health care
system were held in New Delhi in 1988 and in Tokyo in 1993, and the World Health
Assembly, in resolution WHA47.12, has stressed the key role pharmacists can play in the
rational use and quality assurance of medicines.
By virtue of their training, pharmacists can play a part in drug regulation and control,
particularly in the evaluation of pharmaceutical formulations at the time of product
registration, and in the licensing and inspection of pharmaceutical manufacturing plants and
distribution channels. In addition to their work in central medical stores, hospitals,
pharmacies and other drug outlets, trained pharmacists may also contribute to quality
assurance by assisting in pharmaceutical manufacture, in drug procurement and in
distribution.
While quality assurance is founded on regulations and standards, it is the people who
enforce the regulations or work to comply with the standards who make the difference
between quality assurance and lack of it. The assurance of quality, safety and efficacy of
medicines is a continuing concern of WHO. This compilation of material is intended to assist
all involved in the manufacture, regulation and distribution of pharmaceuticals to achieve
these aims more effectively.
