NAPROSYN (Naproxen)

INTRODUCTIONNaprosyn is a propionic acid derivative with,

Rapid, reversible, competitive inhibition of cyclo-oxygenase enzyme,

analgesic action, anti-inflammatory action, potent inhibitor of leukocyte migration has a long half life,

PHARMACODYNAMICSNaprosyn is a non selective NSAIDs with anti-inflammatory, analgesic, and antipyretic effects. Naprosyn inhibits both COX-1 and COX-2 enzymes which are required for PGs synthesis.

PHARMACOKINETICSAbsorption

Completely absorbed from gut Peak levels are achieved with 2 hours Less presystemic metabolism (< 5%) therefore high bioavailability Food slightly delays absorption with no effect on total absorption.

Distribution Highly protein bound > 99%. Therefore less volume of distribution

(0.91 lit/kg) Plasma half life - 12-15hrs Steady state concentration achieved within 3 days Binding to albumin is reduced in cirrhosis and in the elderly.

Synovial fluid concentrations of naproxen increase from 50% of serum levels at 3 to 4h to 74% at 15h. A steady state therefore synovial fluid concentrations are equivalent to those in plasma. It crosses the placenta within 20 to 30 min of oral administration and appears in the milk of lactating women at approximately 1% of maternal plasma concentrations. Concentrations achieved in synovial fluid is half (52%) that of steady state plasma concentration

COMPOSITION

Naproxen Sustained Release Tablets 750mg

INTRODUCTION

Naproxen is a propionic acid derivative with, Rapid, reversible, competitive inhibition of Cyclo-oxygenase , Analgesic action, Anti-inflammatory action, Has a long half life, Potent inhibitor of leukocyte migration.

Naprosyn SR is a sustained release form of Naproxen. In Naprosyn SR Naproxen is released as 10 % immediate release and 90% over a period of 22hrs.

MATRIX TECHNOLOGY

Naprosyn SR involves hydrophilic Hydroxypropyl Methylcellulose [HPMC]The classification of matrix systems is based on matrix structure, release kinetics, controlled release properties (diffusion, erosion, swelling), and the chemical nature and properties of employed materials Matrix systems are usually classified in 3 main groups: hydrophilic, inert, and lipidic.

The matrix system has several advantages as follows,

1. It is very simple and easy to establish a stable formulation.2. The tablet is completely dissolved and thus achieves good bioavailability.3. Offers sustained release of drug with OD advantage

Figure 1 illustrates the schematic dissolution profile of the matrix tablet.

After administration, hydrophilic matrix tablets made with HPMC hydrate to form a gel layer, which regulates the drug release pattern. The most important aspect of this matrix system is the homogeneity of HPMC particle distribution in the tablet. The selection of HPMC grades affects the initial wetting, swelling, hydration and gel strength.

Naprosyn SR FAQ

1.What is Naprosyn SR?Naprosyn SR is a sustained release form of Naproxen. In Naprosyn SR Naproxen is released as 10 % immediate release and 90% over a period of 22hrs.

2.What is the sustained release technology & what are their benefits?In Sustained release technology, the release of drug is modified in such a way that it maintains the levels of drug for a longer duration than the regular drug.The obvious benefit of sustained release drug is improved compliance of the patient.The drug level in the blood of the patient is adequate to provide the required pain relief or analgesia.

3.What is the matrix technology?Matrix is a mould in which a drug is embedded. The classification of matrix systems is based on matrix structure, release kinetics, controlled release properties (diffusion, erosion, swelling), and the chemical nature and properties of employed materials Matrix systems are usually classified in 3 main groups: hydrophilic, inert, and lipidicThe matrix system has several advantages as follows,

1. It is very simple and easy to establish a formulation.

7

2. The tablet is completely dissolved and thus achieves good bioavailability.3. Offers sustained release of drug with OD advantage

4.What is the polymer used in Naprosyn SR?Naprosyn SR involves hydrophilic Hydroxypropyl Methylcellulose [HPMC] as a polymer.

5.What are the indications & dosages of Naprosyn SR?In contrast to plain Naprosyn, the indications of Naprosyn SR are not acute but the maintenance of chronic conditions like Osteoarthritis, Rheumatoid arthritis etc. The usual dose is 750 mg once a day after meals. 6.What is duration of Naprosyn SR treatment?The duration of Naprosyn SR will be same as Naprosyn which has been used from 1 year to 4 years as per the clinical trials depending upon the need & tolerability of the individual patient. But the common principle of NSAID prescription applies here in which the drug has to be used for minimum possible time & if at all required to be used for longer duration, a gap of 15 days is given after 1 to 3 months along with monitoring his GI, Renal & Cardiac status.

7.What are the adverse events of Naprosyn SR?The adverse events of Naprosyn SR are same as that of plain Naprosyn.

8.What are the advantages of Naprosyn SR over Naprosyn?Both dosage formulations are important but the choice will depend upon the doctor to use it. Usually doctors prefer to write plain NSAID for acute conditions & sustained release for maintenance of chronic conditions.

9. What precautions are to be taken during Naprosyn SR treatment?Apart from the usual precautions which are taken for any NSAID prescription like history of the patient, allergy to NSAIDs in the patient etc, the most important thing during Naprosyn SR therapy is that the tablet should not be chewed but swallowed as a whole because if the tablet is chewed all the advantage of sustained release will be lost.

10. How Naprosyn SR acts for 24 hrs when the GI transit time in not more than 6 to 8 hrs?This is the most commonly asked question for all the sustained release formulations. There are two ways to answer this. First is the Bioequivalence study in which our drug is compared with the already available brand in the market and both of them show similar dissolution profile. Second logical answer which is commonly given is that because of the cellulose present in the polymer the drug sticks to the microvillus of the small intestine from where it is slowly absorbed into the circulation so that even if the food moves ahead the drug still remains in the small intestine.Thirdly , as the water , gastric & intestinal secretions enter inside the Hydrophilic Matrix, the polymer in the matrix swells

up. This displaces the drug (Naproxen) from the matrix. Intially there will be rapid release of the drug in the 1st hour (10%) and then there will be gradual release of the drug (90%) over a period of 24 hours. In the latter part, when all the drug is released, this matrix undergoes normal wear and tear as seen in any tablet (disintegration), and is excreted out in the faeces. There is no “Ghost Tablet” seen in faeces as is common with few SR preparations.

16.What are the other brands of Naprosyn SR available in the market?Following brands are available in the marketXenar CR (750 mg) by Elder pharmaceuticals

USPs of the Product Naproxen in Naprosyn SR is the S isomer which active form of Naproxen

molecule responsible for the analgesic effects. Naprosyn SR 10% immediate release and 90% sustained released over a

period of 24 hrs.Thus a sustained pain relief for 24 hrs. Once day dosage. Since Naproxen is released in the Intestine in small packets (small

Quantity) ,the GI side effects are much less . Naprosyn SR taken at night time assures pain relief at early morning hour

for the patients suffering from Rheumatoid arthritis and Osteoarthritis.Thus provides a Good pain free morning for patients suffering from Morning Sickness.

Lesser GI side effects and Convenient dosage schedule make it a drug of choice for chronic painful conditions.

RELIGEL (TOPICAL GEL)

PHARMACOLOGICAL ROLE OF EACH INGREDIENTS ROLE OF OLEUM LINI

Also called as linseed oil is extracted from the seed of the plant Linum usitatissium

PHARMACOLOGY

Linseed oil predominantly contains alpha linolenic acid, which has anti inflammatory activity. On topical application alpha linolenic acid is absorbed into the systemic circulation, on metabolism it produces Eicosapentaenoic acid (EPA), EPA in the presence of the enzyme cyclo-oxygenase and lipooxygenase gets converted into PGE3 and PGF3 and leukotriene LTA5, LTB6 & LTC5 respectively.

PGE3 is a relatively non-inflammatory prostaglandin while LTA5, LTB6 and LTC5

possesses1-10% of the inflammatory activity compared to that of leukotrines produced by arachidonic acid.Further the presence of EPA prevents the action of cyclo-oxygenase on arachidonic acid which reduces its conversion to PGE2. Although PGE3 is relatively non-inflammatory but it still acts as a useful negative feedback regulator to modulate the inflammatory responses and reduce the production of PGE2

- linolenic acid Eicosapentaenoic acid (EPA)

PGE3

Leuktrines (LTA5, LTB5,

LTC5)

Arachidonic acid PGE2

Thus alpha linolenic acid possesses anti-inflammatory activity by decreasing the formation of PGE2 by producing relatively non inflammatory PGE3

By producing PGE3 which acts as a negative feedback regulator to reduce the conversion of arachidonic acid to PGE2.

ROLE OF DICLOFENAC DIETHYLAMMONIUM

Diclofenac diethylammonium is a clinically proven topical NSAID in the treatment of pain and inflammation associated with musculoskeletal disorders.

13

COX Lipooxygenase

COX

- ve

PHARMACOLOGY

Diclofenac exhibits its anti-inflammatory activity by dual mode of action. It prevents the conversion of arachidonic acid to PGE2 by inhibiting the enzyme cyclo-oxygenase. More over it also enhances the uptake of arachidonic acid into the phospholipid pool.The uptake of AA into the phospholipid pool limits the availability of AA into the lipo-oxygenase pathway the resultant effect is a decrease in PGE2 and LTB4 which together effectively counteracts the clinical signs and symptoms of inflammation. Thus Diclofenac and alpha linolenic acid work synergistically.

ROLE OF METHYL SALICYLATE

Methyl Salicylate is used topically as a counter irritant. on topical application it is absorbed through the skin and is applied for the relief of pain in rheumatic conditions and painful muscles and joints.

ROLE OF MENTHOL

On topical application menthol dilates the blood vessels causing a sensation of coldness followed by an analgesic effect. Menthol also acts as a penetration enhancer. It increases the penetration of the drugs when applied on the skin to give a faster onset of action. Menthol acts as a penetration enhancer either due to its vasodilation property or as it readily penetrates the skin.

Cefixime

Nufex-beta(Cefixime+Clavulanate)

Description :

Cefixime is a white to light yellow powder. Slightly soluble in water,soluble in methanol.Cefixime is an oral betalactam antibiotic in a class of drugs called cephalosporin’s. Cefixime is the third generation cephalosporin. Cefixime fights bacteria in the body. Cefixime is used to treat many different types of bacterial infections.

Molecular Formula: C16H15N5O7S2

Molecular Weight: 453.452 g/mol

Clavulanic acid is a beta-lactamase inhibitor sometimes combined with penicillin group antibiotics to overcome certain types of antibiotic resistance. It is used to overcome resistance in bacteria that secrete beta-lactamase, which otherwise inactivates most penicillin’s.

The name is derived from the Streptomyces clavuligerus, which produces clavulanic acid. Clavulanic acid is biosynthetically generated from the amino acid arginine and the sugar glyceraldehyde 3-phosphate.

Molecular Formula: C8H9N O 5

Molecular Weight: 199.16g/mol

MOA of Cefixime

Cefixime inhibits cell wall synthesis in actively dividing microbial cells.As the shape & structure of Β-lactams resembles with the peptide chains & hence does not allow the cross linkage of cell wall & makes the cell wall fragile.

MOA of Clavulanic acid

16

Clavulanic acid has negligible antimicrobial activity. Clavulanic acid act as a competitive inhibitor of beta-lactameses, an enzyme which destroys the beta-lactam ring of the cefxime. If this beta-lactam ring is destroyed , then cefixime will not be able to inhibit the cell wall synthesis of the organism.

negative and positive organisms.

Indication:Pharyngitis Tonsillitis Otitis mediaSinusitisAcute bronchitisPneumoniaTyphoidAcute uncomplicated PylonephritisCystitis Urethritis Uncomplicated Gonorrhea

ContraindicationNufex Beta is contraindicated in patients with known allergies to the cephalosporin or penicillin antibiotics. Precaution If an allergic reaction to Nufex Beta occurs, the drug should be discontinued, and, if necessary, the patient should be treated with appropriate agents, e.g., pressor amines, antihistamines, or corticosteroids.Nufex Beta should be prescribed with caution in patient with history of gastrointestinal disease.Renal Impairment:Nufex beta may be administered in the presence of impaired renal function, but dose modification is recommended for patients with moderate or severe renal impairment (i.e., creatinine clearance of < 40 mL/min).

Adverse Drug ReactionHeadaches, Dizziness, Diarrhea , Stool changes ,Nausea , Abdominal pain , Dyspepsia Flatulence and Vomiting. Transient elevations of SGPT, SGOT and alkaline phosphatase.Transient elevations in Blood Urea Nitrogen (BUN) or creatinine.Skin rashes, Drug fever and pruritus. Anaphylactic reactions (urticaria and angioedema) have been reported rarely.

Dosage & administrationAdults:The recommended dose of cefixime Nufex beta is 400 mg once daily. When necessary, a dose of 200 mg (one-half of a 400 mg tablet) given twice daily may

18

be considered except for urinary tract infections where once daily dosing must be used.For treatment of uncomplicated gonococcal infections, a single oral dose of 400 mg is recommended.

Children:The recommended dose of cefixime in Nufex beta is 8 mg/kg/day once daily. When necessary, a dose of 4 mg/kg given twice daily may be considered except for urinary tract infections where once daily dosing must be used.

Rationale for a beta lactam-beta lactam inhibitor combination antibioticAs the usage of cephalosporin’s has increased globally the resistance to this group of antibiotic has also increased.Hence to overcome this resistance a Combination of cephalosporin’s with beta lactamase inhibitors is an attractive preposition for following reasons.

Production of beta lactamase is the most common mechanism of resistance to beta lactam antibiotics, especially in gram negative bacteria.

Convenience of use and more essentially an understanding that using such combination empirically may help in not only overcome therapeutic failures due to resistant bacteria but will also delay resistance development in susceptible bacteria.

Minimize use of newer antibacterial so that they remain effective antibacterial for specific use.

Has a broad spectrum antibiotic activity. Highly effective combination in switch therapy Well established safety and efficacy profile

Nufex-Beta in Pneumonia

Pneumonia is an inflammatory illness of the lung. Frequently, it is described as lung parenchyma/alveolar inflammation and abnormal alveolar filling with fluid.Cause- Pneumonia can result from a variety of causes, including infection with

bacteria, viruses, fungi, or parasites, and chemical or physical injury to the lungs.

Symptoms- Cough producing greenish or yellow sputum, or phlegm. High fever that may be accompanied by shaking chills. Shortness of breath Chest pain,

19

Cough up blood, Loss of appetite Blueness of the skin, nausea, vomiting

Pathophysiology:The most common causes of pneumonia are viruses and bacteria. Less common causes of infectious pneumonia are fungi and parasites.

Virus: Influenza virus,

Bacteria: Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Moraxella catarrhalis. Chlamydophila pneumoniae, Mycoplasma pneumoniae, and Legionella pneumophila

Clinical classification

Community-acquired pneumonia

Community-acquired pneumonia (CAP) is infectious pneumonia in a person who has not recently been hospitalized. CAP is the most common type of pneumonia. The most common causes of CAP include Streptococcus pneumoniae, viruses, the atypical bacteria, and Haemophilus influenzae. Overall, Streptococcus pneumoniae is the most common cause of community-acquired pneumonia worldwide.

Hospital-acquired pneumonia

Hospital-acquired pneumonia, also called nosocomial pneumonia, is pneumonia acquired during or after hospitalization for another illness or procedure with onset at least 72 hrs after admission. The causes, microbiology, treatment and prognosis are different from those of community-acquired pneumonia. Up to 5% of patients admitted to a hospital for other causes subsequently develop pneumonia. Hospital-acquired microorganisms may include resistant bacteria such as MRSA, Pseudomonas, Enterobacter, and Serratia.

Why Nufex-Beta in pneumonia?

20

1.Cefixime in Nufex-beta is having very low mic against most common pathogen responsible for causing pneumonia hence achieve high kill rate & better cure rate.

  H. influenzaea M.catarrhalis S.pneumoniae

Cefuroxime 2 2 0.12

Cefixime 0.13 .40 0.29

Cefpodoxime 0.12 0.50 .03

Co – amoxy clav

0.5 0.5 0.02

2. As per American Family Physician when clinician cause of concern is Beta lactamase positive H.Influenzae the first drug of choice is cefixime.

3. As per Clinical Drug Investigation The concentrations of cefixime found in bronchial mucosa exceeded these MIC90 values 4.3 ± 0.6 hours after the last dose. However, 8 hours after a 400mg oral dose, lung parenchyma concentrations were higher than MIC90 values for sensitive strains. This ensures better cure with cefixime as compared with other cephalosporins.

4. The majority of pathogens causing acute bacterial LRTIs are primarily located extracellularly, and for this reason there is a consensus that antibiotics should be present in the extra cellular fluid. The concentration of cefixime in ECF exceeds the mic of common respiratory pathogen & ensures better cure & concentrations of cefixime in ECF is sufficient to inhibit H. influenzae and S. pneumoniae.

5. As per Chemotherapy 1998 Cefixime is one such agent, which possesses excellent efficacy against a broad spectrum of pathogens, including Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis. Clinical success rates are similar to cefaclor, clarithromycin, and other cephalosporins. Importantly, cefixime also possesses excellent activity against beta-lactamase-producing strains.

6. Cefixime is the most preferred drug as a switch therapy as it offers coverage & efficacy at par with most intravenous agent.

2. Cefixime is an extended spectrum cephalosporin that has been shown to be more effective than amoxicillin in treating OM caused by Haemophilus influenzae. (Pediatr. Infect. Dis. J., 13, S30 (1994). )

3. Amoxicillin-clavulanic acid is having excellent coverage against S. pneumoniae but major concern is diarrhea which affects the compliance.

4. Amoxicillin-clavulanic exhibit inoculum effect whereas cefixime do not exhibit inoculum effect.

5. AOM is likely to be caused by betalactamase-producing Haemophilus influenzae or Moraxella catarrhalis & Two beta-lactamase-stable agents commonly used for empirical treatment of AOM are amoxicillin/clavulanate and cefixime. Studies has demonstrated that CFX has comparable clinical efficacy and a better adverse events profile than A/C when used to treat AOM of childhood. (Pediatric Drugs )

NUFEX

INTRODUCTION

Nufex contains Cephalexin which belongs to first generation Cephalosporin, oral administration. It is a semi-synthetic analog of Cephalosporin.

PHARMACODYNAMICS

Inhibition cell wall synthesis of bacteria.

PHARMACOKINETICS

Nufex is acid stable and may be given without regard to meals. It is rapidly absorbed after oral administration.

Nufex following doses of 250 mg, 500 mg, and 1 g, average peak serum levels of approximately 9, 18, and 32 μg/ml respectively were obtained at 1 hour.

Measurable levels were present 6 hours after administration. Nufex is excreted in the urine by glomerular filtration and tubular secretion.

Studies showed that over 90% of the drug was excreted unchanged in the urine within 8 hours.

During this period, peak urine concentrations following the 250 mg, 500 mg, and 1 g doses were approximately 1000, 2200, and 5000 μg/ml respectively

RECOMMENDED DOSAGE

ADULTS

The dosage ranges from1-4g daily in divided doses. For skin and soft tissue infections, streptococcal pharyngitis and mild, uncomplicated urinary tract infections, the usual dosage is 250mg every 6 hours, or 500mg every 12 hours. Cystitis therapy should be continued for 7-10 days. For most acute infections, treatment should continue for at least 2 days after symptoms have subsided. In severe systemic infections doses upto 4g/day can be used. In chronic recurrent or complicated urinary tract infections and syphilis, 500mg cephalexin should be given every 6 hours for two weeks.

Gonorrhoea - a single dose of 3g with 1g probenecid for males or 2g with 0.5g probenecid for females is usually effective.

CHILDREN

Usual recommended dose in divided doses is 25-50mg/kg/day for most-infections and upto 100mg/kg/day for chronic, severe or deep-seated infections. For skin and soft tissue infections, streptococcal pharyngitis and mild, uncomplicated urinary tract infections, total daily dose may be administered every 12 hours.

27

For most infections dosage schedule suggested is:

Neonates : 62.5 - 125mg bid1-5 yrs : 125mg tid6-12 yrs : 250mg tid

In severe infections dosage may be doubled. In otitis media, dose of 75-100mg/kg/day in 4 divided doses may be required.

In treatment of beta hemolytic streptococcal infections, therapeutic dose is to be administered for atleast 10 days.

IN RENAL FUNCTION IMPAIRMENT

When renal function is impaired the dosage of cephalexin should be reduced to prevent accumulation as follows:

The dosing intervals should be longer. The following guidelines for approximate dosing intervals are recommended:

Creatinine Clearance (ml/min)

DOSAGE AND ADMINISTRATION

The sustained release tablets should not be cut, crushed or chewed but should be swallowed whole with a glass of water.

Usual Adult Dosage :

750 mg twice daily. In milder infections, 375 mg twice daily may be given.In severe infections, 2 tablets of 750 mg two times daily may be given. A maximum dose of 4 g/day should not be exceeded.

NOTE :

375 mg Cephalexin sustained release tablet administered twice a day is clinically equivalent to 250 mg Cephalexin conventional release tablet administered thrice a day.

750 mg Cephalexin sustained release tablet administered twice a day is clinically equivalent to 500 mg Cephalexin conventional release tablet administered thrice a day.

IN RENAL FUNCTION IMPAIRMENT

No dosage adjustments are essential for patients with a creatinine clearance greater than 50 ml/min. For patients with renal dysfunction, or renal failure dosage should be reduced.

SIDE EFFECTS

The common side effects with cephalexin are diarrhoea, nausea and vomiting. Headache, dizziness, allergic reactions and raised serum transaminase levels have also been reported. Eosinophilia and very rarely neutropenia, which is reversible, have occurred in a few patients.

As with other broad spectrum antibiotics overgrowth of Candida and rare instances of pseudomembranous colitis can occur.

PRECAUTIONS

Cephalexin should be administered with caution in the presence of markedly impaired renal function. Dosage of cephalexin in such cases should be suitably reduced.

31

In patients receiving cephalexin, false positive reaction for glucose in the urine may occur with copper reduction reagents (Benedict’s or Fehling’s solution or with ‘Clinitest’ but not with enzyme based tests, e.g. ‘Clinistix’).

Positive direct Coomb’s tests have been reported during treatment with cephalosporin antibiotics.

Generally cephalexin is well tolerated by patients sensitive to penicillin but as cross reactions have been encountered rarely, cephalexin should be given cautiously to penicillin sensitive patients.

Use of any drug in women of child bearing potential requires that the benefits of the therapy be weighed against possible hazards to the mother and foetus. However, laboratory and clinical experience to date has shown no evidence of teratogenicity.

OVERDOSAGE

Serum levels of cephalexin can be greatly reduced by peritoneal dialysis or haemodialysis.

STORAGE

In a cool, dry place.

35

Composition Each enteric coated Rabee 20mg tab.Contains: Rabeparazole sodium 20mg

DescriptionRabeprazole is an oral drug that is used for the treatment of conditions caused by acid. It is in a class of drugs called proton pump inhibitors or PPIs. Other drugs in the same class include lansoprazole, omeprazole, pantoprazole ,and esomeprazole .

MOARabee act by irreversibly blocking the hydrogen/potassium adenosine triphosphatase enzyme system (the H+/K+ ATPase, or more commonly just gastric proton pump) of the gastric parietal cell. The proton pump is the terminal stage in gastric acid secretion, being directly responsible for secreting H+ ions into the gastric lumen, making it an ideal target for inhibiting acid secretion.

Targeting the terminal-step in acid production, as well as the irreversible nature of the inhibition, results in up to 99% reduction of gastric acid secretion.

What is the evidence in favour of Rabee providing additional cytoprotection?Rabeprazole is a unique PPI in providing added cytoprotective action by enhancing mucus production and by increasing viscosity translating to cytoprotection provided to mucosa cells. This action may be responsible for superior healing rates and maintenance of healing with Rabeprazole.Rabeprazole has unique pharmacological property of augmenting the production of gastric mucus and mucin, which may provide additional protection to mucosa during acid related challenge.

Rabee-DCompositionRabee –D is a capsule containing Rabeprazole sodium 20 mg (as enteric coated pellets) and Domperidone BP 30 mg (as sustained release pellets).

DescriptionRabeprazole is an oral drug that is used for the treatment of conditions caused by acid. It is in a class of drugs called proton pump inhibitors or PPIs. Domperidone is a dopamine antagonist with anti emetic and gastroprokinetic properties.

MOARabeprazole act by irreversibly blocking the hydrogen/potassium adenosine triphosphatase enzyme system (the H+/K+ ATPase, or more commonly just gastric proton pump) of the gastric parietal cell. The proton pump is the terminal stage in gastric acid secretion, being directly responsible for secreting H+ ions into the gastric lumen, making it an ideal target for inhibiting acid secretion. Targeting the terminal-step in acid production, as well as the irreversible nature of the inhibition, results in up to 99% reduction of gastric acid secretion.The mechanism of action of domperidone is related to its peripheral dopamine receptor blocking properties.

Domperidone does not readily cross the blood-brain barrier and therefore is not expected to have central effects.

Pharmacology Rabeprazole : Refer Rabee

Domperidone Absorption: Domperidone is rapidly absorbedProtein Binding: 91-93%Metabolism: HepaticExcretion: Approximately 31%in urine, 66% in the feces.Half life 7-9 hours

Contraindication

The fixed dose combination of Rabeprazole and Domperidone is contraindicated in patients with known hypersensitivity to either drug or their substitutes. Also fixed dose combination is contraindicated in the presence of gastro-intestinal hemorrhage, obstruction or perforation.

Drug to drug interactionDrugs like warfarin, theophylline, diazepam, phenytoin, anticholinergic drugs, Antimuscarinic agents and opiod analgesics must be used with caution while administering this combination.

39

Adverse Drug ReactionIn general, both the drugs separately are well tolerated. Following adverse drug reactions may occur with this fixed drug combination headache, asthenia, skin rash, diarrhea, flatulence, constipation and dry mouth.

Indication1. Dyspepsia 2. GERD 3. Nausea associated with acid peptic disorders 4. Post-operative nausea and vomiting 5. Chronic gastritis

Dosage & Administration

Indication Dose

GERD in adults One cap. daily for 4-8 weeks & If healing does not occur after 8 weeks, another 8 week course may be considered.

Heartburn One cap. daily for 4 weeks and an additional 4 weeks if symptoms do not resolve.

Capsule should be swallowed whole and should not be crushed, split or chewed. Rabeprazole can be taken with or without meals since food has little effect on its absorption.

RATIONALE OF COMBINATION THERAPY

1. Hyperacidity and Hypomotility are common GIT problems and frequently coexist together.

2. Excess hydrochloric acid and defective clearance of the acid and other gastric content from the stomach together or individually give rise to nausea, vomiting and upper abdomen discomfort due to irritation of gastric mucosa.

3. Only acid suppression or only prokinetic therapy by itself would not serve the purpose.

4. Rabeprazole a PPI is a drug of choice for acid suppression and Domperidone is drug of choice for stimulation of gastric motility.

5. Both the drugs are devoid of any major side effects. Domperidone does not cross Blood Brain Barrier (BBB), so no extra pyramidal syndrome.

6. Both the drugs are in pellet form. Different colour pellets are packed in same

40

capsule, so the compliance of the patient will be excellent.

7. Domperidone has short half-life, which makes it necessary to take it three times a day. Therefore it has been formulated as sustained release pellets. The advantages of domperidone sustained release pellets include round the clock symptom control, better patient compliance with fewer side effects.

8. Rabeprazole 20mg is formulated as enteric-coated pellets. It reduces fluctuations in drug plasma concentrations improves effectiveness and controls the site of drug delivery in the GI tract.

9. Combination of Rabeprazole and Domperidone gives a complete symptomatic relief from Dyspepsia, heartburn, and Acid-Pepsin disorder associated with nausea, vomiting and epigastric pain.

Product Manual: Rabeprazole 20 mg + Itopride ER 150 mg

PROKINETICS

In general, GI motility is mainly described as peristalsis. Peristalsis is controlled by 3 mechanisms.1. Mechanical - Presence of bolus of food or distension of gut stimulates peristalsis.2. Nervous - It is central in origin. The vagus nerves innervate the smooth muscle through the

myentric plexus. The myentric plexus is the programmer for all motility programs in the GIT e.g. it regulates the following functions.i. Reservoir function - e.g. in fundus of stomach.ii. Mixing function - e.g.in small intestine.iii. Barrier function e.g. in LESiv. Propulsive function at all levels.The inputs come from mechanical and chemical receptors in gut wall & CNS. Hence it is called "little brain" or "gut brain".

3. Chemical - Through neurotransmitters mainly acetylcholine.

Any impairment in GI motility leads to reflux of the contents, vomiting, nausea, and constipation. Also symptoms like heartburn, nausea, vomiting, regurgitation, dyspepsia, pain.

Other condition in which there can be GI motility impairment is gastroparesis i.e. paralysis of gut wall. It presents itself as a motility disorder of poor gastric emptying.

The drugs used in the treatment of these hypomotility conditions are prokinetics. Antidopaminergic drugs can also be used but they may precipitate side effects.

What is Itopride?

Itopride is a prokinetic benzamide derivative. This drug inhibits dopamine and has a gastrokinetic effect (result in increased gastrointestinal motility)

What are the pharmacological actions of Itopride?

Itopride increases acetylcholine concentrations by inhibiting dopamine D2 receptors and acetylcholinesterase. Higher acetylcholine increases GI peristalsis, increases the lower esophageal sphincter pressure, stimulates gastric motility, accelerates gastric emptying, and improves gastro-duodenal coordination.

Clinical Use and Dosage:

Typically, itopride is indicated in the treatment of GI symptoms caused by reduced GI motility:

dyspepsia of a non-ulcer type (gastric "fullness", discomfort, and possible pain) anorexia heartburn regurgitation bloating

43

nausea and vomiting other possible gastric, prolactin, or dopamine related conditions

Typical adult dosage is usually 150mg/24hrs in 3 divided doses. However, Itopride ER 150 mg is administered once a day. The dose is usually taken on an empty stomach about an hour before meals. However, the dosage and details of administration may vary depending on the patient’s age, symptoms, and other factors.

Itopride was shown to significantly improve symptoms in patients with functional dyspepsia and motility disorders in placebo-controlled trials.

Contraindications and precautions

Itopride is contraindicated in hypersensitivity to itopride or benzamides; lactation, GI hemorrhage, obstruction or perforation. Itopride may not be indicated for those suffering from Parkinson's disease or other conditions involving dopamine regulation issues. Itopride should be used with special caution in the young and the elderly. Little information is available at this time regarding the safe use of itopride during pregnancy.

Adverse drug reactions

Some common side-effects of itopride may include: rash, diarrhoea, giddiness, exhaustion, back or chest pain, increased salivation, constipation, abdominal pain, headache, sleeping disorders, dizziness, galactorrhea, and gynecomastia.

Other side-effects may also be present.

Leukopenia, a reduction in the normal level of white blood cells, can be a potentially life-threatening reaction to itopride.

PROTON PUMP INHIBITORS

PPIs act by inhibiting the proton pump H+-K+-ATPase which is the ultimate mediator of gastric acid secretion. As the name suggests H+-K+-ATPase is an enzyme which utilizes ATP to catalyse the outward transport of H+ in exchange for the inward transport of K+.

All available Pips viz. Omeprazole, lansoprazole and pantoprazole being weak bases, accumulate in the acidic compartment of parietal cells and get highly ionized at low pH. They are prodrugs, which are rapidly converted to the active form,, cationic sulfenamides. These bind covalently to the cysteine molecules of H+-K+-ATPase, thus blocking the H+-K+-channels of the enzymes involved in the expulsion of H in exchange for K . Since activation of H+-K+-ATPase is the terminal step in the gastric acid secretion, PPIs inhibit HCl acid secretion in response to all stimulii.

What is Rabeprazole?

Rabeprazole is an antiulcer drug in the class of proton pump inhibitors.

44

Clinical Use and Dosage:

Gastric ulcer Peptic ulcer (PUD) Maintenance of Healing of Erosive or Ulcerative GERD Healing of Erosive and Ulcerative GERD Healing of Duodenal Ulcers.

Pregnancy Lactation

Adverse drug reactions

Some common side-effects of Rabeprazole may include: headache, diarrhea , vomiting, nausea, abdominal pains , constipation, meteorism, dry mouth, increased or decreased appetite, asthenia , headache, anxiety, sleeplessness, vertigo, thrombocytopenia, granulocytopenia, leukocytopenia, skin eruption, erythema, myalgia, arthralgia, muscle or bone pain

Other side-effects may also be present.

Pharmacokinetics:

Rabeprazole + Itopride Rationale for combination:In GERD, treatment aims at decreasing the amount of reflux or reducing damage to the lining of the esophagus from refluxed materials. Thus, Itopride by increasing acetylcholine concentrations by inhibiting dopamine D2 receptors and acetylcholinesterase, increases GI peristalsis, increases the lower esophageal sphincter pressure, stimulates gastric motility, accelerates gastric emptying, and improves gastro-duodenal coordination and thus decreases the amount of reflex. On other hand Rabeprazole reduces the damage to the esophagus lining by

ANTACIDS

These are oral medications that neutralize the amount of acid present within the stomach or duodenum or esophagus. These medications act quickly but by different mechanisms than histamine to receptor antagonists and proton pump inhibitors. Antacids typically act by directly neutralizing the HCL (hydrochloric acid) present within the stomach or duodenum or esophagus.

46

COMPOSITION

Aluminum hydroxide 300mgMagnesium hydroxide 150 mgSimethicone 125 mg Oxethazaine 10 mg

PHARMACODYNAMICS

Alumina gel and magnesium hydroxide react chemically to neutralize or buffer existing quantities of acid, but have no direct effect on its production.

Oxethazaine exerts a prolonged topical anaesthetic action.Oxethazaine is a topical anaesthetic, which, when applied to the mucous membranes produces a more potent anaesthesia of longer duration than either cocaine hydrochloride or lidocaine hydrochloride. Simethicone is used to help relieve pain and bloating caused by trapped wind. It works by bringing together all the small bubbles of gas to form a large bubble, which is expelled either by belching or flatulence.

PHARMACOKINETICS

Studies have shown that a small amount of aluminium from aluminium hydroxide is absorbed from the intestine. Approximately 10% of the magnesium in agnesium hydroxide is absorbed from the intestine.After oral administration of oxethazaine contained in 10 mL of alumina gel with magnesium hydroxide, the peak oxethazaine plasma level was approximately 20 ng/mL and occurred about one hour after dosing.Oxethazaine undergoes rapid and extensive biotransformation resulting in a short plasma half-life of approximately one hour. Less than 0.1% unchanged oxethazaine was recovered in the urine within 24 hours. Major metabolites were beta-hydroxy-mephentermine and beta-hydroxy-phentermine. Mephentermine and phentermine appeared in the plasma in pharmacologically insignificant amounts and their cumulative 24-hour urinary excretion was less than 0.1% of the dose administered.Simethicone not absorbed.

INDICATIONS

It acts as an antacid in dyspepsia and is used for the symptomatic relief of hyperacidity associated with peptic ulcer, gastritis, esophageal reflux with heartburn. It may be of benefit if symptomatic relief could not be obtained with antacid therapy alone.

Daslin NF Cough Syrup

Composition:

Each 5ml contains:Loratadine HCL USP 5 mgAmbroxol HCl BP 30 mgGuaiphenesin IP 50 mgMenthol IP 0.5 mg

49

Loratidine:Loratidine, a piperidine derivative related to azatadine is a non-acting, non-sedating antihistamine with no significant muscaranic activity. It is used for the symptomatic relief of allergic conditions in Rhinitis.

In Seasonal allergic Rhinitis, the recommended dosage of Loratidine in adults is 10 mg once daily.

In children aged between 2-5 years of age the recommended dosage is 5 mg once daily.

Ambroxol:

Ambroxol is a metabolite of Bromhexine. It is a mucolytic agent. Studies showed that it enhances both bronchial glandular cell secretions. These secretions get mixed with the thick mucus thereby reducing its viscosity and helping easy expectoration. It also stimulates cilliary motility and accelerates mucocilliary transport.

Studies have also shown that Ambroxol affects the secretomotor activity of serous glands, facilitates the repair of bronchial epithelium and accelerates mucociliary transport and clearance.

It has daily dose of 30 to 120 mg by mouth in to 2 to 3 divided doses. It is rapidly absorbed from the gastrointestinal tract and has a very high bioavailability.Ambroxol is been seen to increase the concentration of antibiotics in the lungs, when co – prescribed.

Guaiphenesin:Guaiphenesin is used as an expectorant in symptomatic management of coughs associated with common cold, bronchitis, laryngitis, pharangytis, pertusis, influenza, measles, and coughs provoked by chronic paranasal sinusitis.Guaiphenesin is an expectorant, which increases the respiratory tract fluid and helps loosen the mucus and bronchial secretions. By reducing the viscosity of secretion, guaiphenesin increases the efficiency of the mucociliary mechanism in removing accumulated secretion from the airways. It has been frequently used in the management of productive cough.

Doses recommended:

Adults: Oral Doses of 200 to 400 mg every 4 hoursChildren 6 to 12 years: 100 to 200 mg every 4 hours.Children 2 to 6 years: 50 to 100 mg every 4 hours.

Codeine Phosphate:Codeine inhibits the receptor in the cough center of the medulla oblongata and acting on the brain to reduce the cough reflex, without the suppression of the respiratory center. Codeine is used in combination with other antitussives or expectorants, in the symptomatic relief of non-productive cough. Since the cough reflex may be useful physiologic mechanism, which clears the respiratory passages of foreign material and excess of secretion and may aid in preventing or reversing atlectasis, cough suppressants should not be used indiscriminately.Dosage: Codeine preparation should be given in the smallest effective dose and infrequently as possible to minimize the development of tolerance and physical dependence. Reduced dosage is indicated in poor risk patients, in very young or very old patients, and in-patients receiving other CNS depressants.

COMPOSITION:Each sugar-coated tablet contains:

Propantheline Bromide IP … 15 mg

What is Pro-Banthine?Pro-Banthine is an anticholinergic drug.

What is anticholinergic drug?An anticholinergic drug is the one that blocks the neurotransmitter called Acetylcholine (Ach).

Thereby, reducing the effects mediated by Ach on its receptors in neurons (eg: reducing the spasms of the smooth muscle).

These drugs act on Ach receptors that are present on smooth muscle in the gut, bladder, etc. This smooth muscle is not under voluntary control.

INDICATIONSIrritable bowel syndrome (IBS)Urinary incontinence and enuresisTo reduce salivation during dental procedures

What is IBS?

IBS – a functional bowel disorder in which abdominal pain or discomfort is associated with defecation or a change in bowel habit and with features of disordered defecation.

Symptoms of IBSThe most common symptom is abdominal pain associated with diarrhea, constipation or both.

• Other symptoms include gas, bloating, cramping and indigestion.

Factors that trigger IBS Symptoms:• Stress• Foods like milk products, chocolate, caffeine,carbonated drinks, alcohol,

and food with high fat content.

Some facts about IBS:• Constitutes a major health problem with gastrointestinal symptoms • The cause of IBS is unknown.• The condition is more frequent in women.

55

What is the role of Role of Ach in the gut?Ach binds to the Ach-receptors in the gut & causes gastric motility. Excess of Ach in gut increases the gastric motility & gives the feeling of frequent defecation.

How does Pro-Banthine help in IBS?• Pro-Banthine works by blocking Ach receptors in gut. This prevents the

action of Ach. Hence, causes smooth muscle to relax .& prevents the muscle spasms occurring in IBS. By relaxing the gut muscle, Pro-Banthine relieves the IBS symptoms.

How does Pro-Banthine help in Urinary Incontinence & Enuresis?Urinary Incontinence (UI):• Any involuntary leakage of urine.

Enuresis (Bed-wetting):• A repeated involuntary or unintentional discharge of urine into bed or

clothes beyond the expected age for controlling urination.

In normal condition Ach. Helps in the contraction of smooth muscle of urinary bladder & helps in urination but when the level of Ach. increases then it causes UI & Enuresis.Pro-Banthine works by blocking Ach receptors in urinary bladder. This prevents the action of Ach hence, causes smooth muscle to relax & prevents the muscle spasms occurring in bladder & prevents the involuntary spasms which can allow leakage of urine from the bladder.

DOSAGE AND ADMINISTRATION: For IBS: 15 mg tid For Urinary Incontinence: 15 mg tid For Enuresis: 15 mg tid and 30 mg during bed-time To reduce salivation during dental surgery:

30 mg one hour before surgery and 15 mg tid Hyperhidrosis: 15 mg tid
