Ketotifen is indicated in the following conditions-

• For the prophylactic treatment of bronchial asthma.
• Symptomatic treatment of allergic conditions including rhinitis and conjunctivitis.
• For alleviating the complications of itching, pain and tenderness associated with neurofibroma.
• Symptomatic treatment of allergy such as hayfever, urticaria.

Cromoglycate & related drugs

Ketotifen has anti-allergic properties and has been used similarly, to sodium chromoglycate in the prophylactic treatment of asthma. It also has the properties of an antihistamine. Ketotifen possesses marked anti-anaphylactic properties and is effective in preventing an asthmatic attacks. Ketotifen exerts as sustained inhibitory effect on histamine reactions, which can be clearly dissociated from its anti-anaphylactic properties. Experimental investigations in asthmatic subjects have shown that Ketotifen is as effective orally as a selective mast cell stabilizer administered by inhalation. Antihistamines were ineffective in those tests. The effectiveness of Ketotifen has been studied in long-term clinical trials. Asthma attacks were reduced in number, severity and duration and in some cases, the patients were completely freed from attacks. Progressive reduction of corticosteroids and/or bronchodilators was also possible. The prophylactic activity of Ketotifen may take several weeks to become fully established. Ketotifen will not abort established attacks of asthma.

Adults: 1 mg twice daily with food. If necessary the dose may be increased to 2 mg twice daily in severe cases.

Children above 3 years: 1 mg twice daily with food. Patients known to be easily sedated should begin treatment with 0.5 to 1 mg at night for the first few days or as directed by the physician.

Use in elderly: Same as adult dose or as advised by the physician.

Drowsiness and in isolated cases, dry mouth and slight dizziness may occur at the beginning of treatment but usually disappear spontaneously after a few days.

A reversible fall in the platelet count has been observed in a few patients receiving Ketotifen concomitantly with oral antidiabetic agent and it has been suggested that this combination should therefore be avoided. Although there is no evidence of any teratogenic effect, recommendations for Ketotifen in pregnancy or when breast feeding can not be given.

It is important to continue the previous treatment for a minimum of two weeks after starting Ketotifen to avoid the possibility of exacerbation of asthma. This applies specially to systemic corticosteroids and ACTH because of the possible existence of adrenocortical insufficiency in steroid dependent patient. If inter current infection occurs, Ketotifen treatment must be supplemented by specific antimicrobial therapy. During the first day of treatment with Ketotifen, reactions may be impaired and patients should be warned not to take charge of vehicle or machinery until the effect of Ketotifen treatment on the individual is known. Patients should be advised to avoid alcoholic drinks. Ketotifen may potentiate the effects of sedatives, hypnotics, antihistamines and alcohol.

Ketotifen may potentiate the effects of sedatives, hypnotics, antihistamines and alcohols. A reversible fall in the platelet count has been observed in a few patients receiving Tifen concomitantly with oral antidiabetic agents and it has been suggested that this combination should therefore be avoided.

Although there is no evidence of any teratogenic effect, Ketotifen in pregnancy and lactation is not recommended.

The reported features of overdosage include confusion, drowsiness, headache, bradycardia, respiratory depression etc. should be watched for. Elimination of the drug with gastric lavage or emessis is recommended. Otherwise, general supportive treatment is all that is required shall be instituted.

Store in a cool and dry place, protect from light. Keep out of the reach of children.

Prucalopride is indicated for symptomatic treatment of chronic constipation in adults in whom laxatives fail to provide adequate relief.

Osmotic purgatives

Prucalopride acts as a selective stimulator of the 5-HT4 receptors while having no interaction with hERG channel or 5-HT1 receptors which reduces significantly the cardiovascular risk found in other similar drugs. 5-HT4 receptors can be found throughout the gastrointestinal tract primarily in smooth muscle cells, enterochromaffin cells, and myenteric plexus. Its activation produces the release of acetylcholine which is the major excitatory neurotransmitter in the GI tract. Hence, prucalopride stimulates motility by interacting specifically with 5-HT4 receptors in the GI tract which causes a release of acetylcholine and further contraction of the muscle layer of the colon and relaxation of the circular muscle layer leading to the propulsion of luminal content.

Adults: 2 mg once daily with or without food, at any time of the day. Due to the specific mode of action of prucalopride (stimulation of propulsive motility), exceeding the daily dose of 2 mg is not expected to increase efficacy.

Older people: Start with 1 mg once daily; if needed the dose can be increased to 2 mg once daily.

Children: Prucalopride should not be used in children and adolescents younger than 18 years

The most frequently reported adverse reactions associated with Prucalopride therapy are headache (17.8%) and gastrointestinal symptoms (abdominal pain), nausea and diarrhoea. The adverse reactions occur predominantly at the start of therapy and usually disappear within a few days with continued treatment. Other adverse reactions have been reported occasionally. The majority of adverse events were mild to moderate in intensity.

Prucalopride is contraindicated in those people who are hypersensitive to the active substance or to any of the excipients and people with renal impairment requiring dialysis.

In-vitro data indicate that, Prucalopride has a low interaction potential and therapeutic concentrations of Prucalopride are not expected to affect the CYP-mediated metabolism of co medicated medicinal products. Although Prucalopride may be a weak substrate for P-glycoprotein (P-gp), it is not an inhibitor of P-gp at clinically relevant concentrations.

Ketoconazole (200 mg b.i.d.), a potent inhibitor of CYP3A4 and of P-gp, increased the systemic exposure to prucalopride by approximately 40%. This effect is too small to be clinically relevant. Interactions of similar magnitude may be expected with other potent inhibitors of P-gp such as verapamil, cyclosporine A and quinidine.

Studies in healthy subjects showed that, there were no clinically relevant effects of Prucalopride on the pharmacokinetics of warfarin, digoxin, alcohol, paroxetine or oral contraceptives.

Prucalopride is not recommended during pregnancy and women of childbearing potential should use effective contraception during treatment. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/fetal development, parturition, or postnatal development. In the absence of human data, it is not recommended to use Prucalopride during breastfeeding

Renal Impairment: The dose for patients with severe renal impairment (GFR <30 ml/min/1.73 m²) is 1 mg once daily. No dose adjustment is required for patients with mild to moderate renal impairment.

Hepatic Impairment: Patients with severe hepatic impairment (Child-Pugh class C) start with 1 mg once daily which may be increased to 2 mg if required to improve efficacy and if the 1 mg dose is well tolerated. No dose adjustment is required for patients with mild to moderate hepatic impairment.

An overdose may result in symptoms resulting from an exaggeration of prucalopride's known pharmacodynamic effects and include headache, nausea and diarrhoea. Specific treatment is not available for Prucalopride overdose. Should an overdose occur, the patient should be treated symptomatically and supportive measures instituted, as required. Extensive fluid loss by diarrhoea or vomiting may require correction of electrolyte disturbances.

Niacin is a preparation of Nicotinic acid. It is proven effective at lowering VLDL, LDL, total cholesterol and triglyceride levels while raising HDL levels. So Niacin has been prescriped for the treatment of cardiovascular disease particularly the hyperlipidemias.

Initial Dose: 500 mg tablet at bedtime from 1 to 4 weeks.

Maintenance Dose: the daily dosage should not be increased by more than 500 mg in any 4 week period. The recommended maintenance dose is 1000 mg (two tablet) to 2000 mg (4 tablets) once daily at bedtime. Dose greater than 2000 mg daily is not recommended. Or, as directed by the registered physician.

Niacin is generally well tolerated; adverse reactions have been mild and transient. The most frequent advers effects were flushing, itching, pruritis, nausea and GI upset, jaundice, hypotension, tachycardia, increased serum blood glucose and uric acid levels, myalgia.

Niacin is contraindicated in patients with a known hypersensitivity to Niacin or any component of this medication, significant or unexplained hepatic dysfunction, active peptic ulcer disease or arterial bleeding.

Before instituting therapy with Niacin, an attempt should be made to control hyperlipidemia with appropriate diet, exercise, and weight reduction in obese patients and to treat other underlying medical problems. Patients with a past history of jaundice, hepatobiliary disease, or peptic ulcer should be observed closely during Niacin therapy. Frequent monitoring of liver function tests and blood glucose should be performed to ascertain that the drug is producing no adverse effects on these organ systems. Diabetic patients may experience a dose-related rise in glucose intolerance, the clinical significance of which is unclear. Diabetic or potentially diabetic patients should be observed closely. Adjustment of diet and/or hypoglycemic therapy may be necessary.

Caution should also be used when Niacin is used in patients with unstable angina or in the acute phase of MI, particularly when such patients are also receiving vasoactive drugs such as nitrates, calcium channel blockers or adrenergic blocking agents. Elevated uric acid levels have occurred with Niacin therapy, therefore use with caution in patients predisposed to gout. Niacin has been associated with small but statistically significant dose-related reductions in platelet count and increases in prothrombin time. Caution should be observed when Niacin is administered concomitantly with anticoagulants; prothrombin time and platelet counts should be monitored closely in such patients. Niacin has been associated with small but statistically significant, dose-related reductions in phosphorus levels (mean of -13% with 2000 mg). So phosphorus levels should be monitored periodically in patients at risk.

Niacin may potentiate the effects of ganglionic blocking agents and vasoactive drugs resulting in postural hypotension. Concomitant aspirin may decrease the metabolic clearance of nicotinic acid. The clinical relevance of this finding is unclear. About 98% of available Niacin was bound to colestipol, with 10 to 30% binding to cholestyramine. These results suggest that 4 to 6 hours, or as great an interval as possible, should elapse between the ingestion of bile acid-binding resins and the administration of Niacin.

Niacin cannot be used in pregnancy and lactation because of a lack of information.

Supportive measures should be undertaken in the event of an overdosage. Symptoms may include nausea, dizziness, itching, vomiting, upset stomach, and flushing

Store in a cool and dry place, protect from light and moisture. Keep all medicines out of the reach of the children.

Cefdinir is indicated for the treatment of Community Acquired Pneumonia, Acute Exacerbation of Chronic Bronchitis, Acute Maxillary Sinusitis, Pharyngitis, Tonsillitis, Uncomplicated Skin and Skin Structure, Infections

Third generation Cephalosporins

Cefdinir binds to 1 or more of the penicillin-binding proteins (PBPs) which inhibit the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.

Adult: 600 mg daily as a single or in 2 divided doses for 5-10 days.
Child: ≥6 months: 14 mg/kg daily as a single or in 2 divided doses. Max: 600 mg daily.

Motility Stimulants, Motility stimulants/Dopamine antagonist, Prokinetic drugs

Domperidone is a dopamine antagonist that principally blocks the dopamine receptors located in the ChemoreceptorTrigger Zone (CTZ) and stomach. Its gastroprokinetic action is based on its blocking effect of dopamine receptors that have an influence on the motility of the gastrointestinal tract. Due to its weak penetration across the blood-brain barrier, Domperidone has almost no effect on the dopaminergic receptors in the brain, therefore, excluding psychotropic and neurologic side effects. Domperidone restores normal motility and tone of the upper gastrointestinal tract, facilitates gastric emptying, enhances antral and duodenal peristalsis and regulates contraction of the pylorus. Domperidone also increases esophageal peristalsis and lower esophageal sphincter pressure, and thus prevents regurgitation of gastric content.

Domperidone should be taken 15-30 minutes before meals and, if necessary, before retiring.

The usual recommended oral dose of Domperidone is as follows:

• Adults: 10-20 mg (1-2 tablet or 10-20 ml suspension), every 6-8 hours daily. The maximum dose of Domperidone is 80 mg daily.
• Children: 2-4 ml suspension/10 kg body weight or 0.4-0.8 ml paediatric drops/10 kg body weight, every 6-8 hours daily.

In dyspeptic symptom:

• Adults: 10-20 mg (1-2 tablet or 10-20 ml suspension), every 6-8 hours daily.
• Children: 0.2-0.4 mg/kg (2-4 ml suspension/10 kg or 0.4-0.8 ml paediatric drops/10 kg) body weight, every 6-8 hours daily.

In acute and sub-acute conditions (mainly in acute nausea and vomiting):

• Adults: 20 mg (2 tablets or 20 ml suspension), every 6-8 hours daily
• Children: 0.2-0.4 mg/kg (2-4 ml suspension/10 kg or 0.4-0.8 ml paediatric drops/10 kg) body weight, every 6-8 hours daily. (In acute nausea and vomiting maximum period of treatment is 12 weeks).

By rectum in suppositories:

• Adults (including elderly): 30-60 mg every 4-8 hours.
• Children: The maximum daily dose rectally in children's is 30 mg for those weighting 10 to 25 kg. The dose may be divided throughout day if necessary.
• The maximum period of treatment is 12 weeks.

Domperidone may produce hyperprolactinemia (1.3%).This may result in galactorrhea, breast enlargement, and soreness and reduced libido. Dry mouth (1%), thirst, headache (1.2%), nervousness, drowsiness (0.4%), diarrhea (0.2%), skin rash and itching (0.1%) may occur during treatment with domperidone. Extra-pyramidal reactions are seen in 0.05% of patients in clinical studies.

Domperidone is contraindicated to patients having known hypersensitivity to this drug and in the case of neonates. Domperidone should not be used whenever gastrointestinal stimulation might be dangerous i.e., gastrointestinal hemorrhage, mechanical obstruction or perforation. Also contraindicated in patients with prolactin releasing pituitary tumor (prolactinoma).

Domperidone should be used with absolute caution in the case of children because there may be an increased risk of extra-pyramidal reactions in young children because of an incompletely developed blood-brain barrier. Since domperidone is highly metabolized in liver, it should be used with caution in patient with hepatic impairment.

Domperidone may reduce the risk of hypoprolactemic effect of bromocriptine. The action of Domperidone on Gl function may be antagonized by antimuscarinics and opoid analgesics. Care should be exercised when domperidone is administered in combination with MAO (monoamine oxidase) inhibitors.

The safety of domperidone has not been proven and it is therefore not recommended during pregnancy. Animal studies have not demonstrated the teratogenic effect in the fetus. Domperidone may precipitate galactorrhea and improve post-natal lactation. It is secreted in breast milk but in very small quantities insufficient to be considered harmful.

There are no reported cases of overdose.

Extra-pyramidal reactions are seen in 0.05% of patients in clinical studies.

Domperidone is contraindicated to patients having known hypersensitivity to this drug and in the case of neonates. Domperidone should not be used whenever gastrointestinal stimulation might be dangerous i.e., gastrointestinal hemorrhage, mechanical obstruction or perforation. Also contraindicated in patients with prolactin releasing pituitary tumor (prolactinoma).

Domperidone should be used with absolute caution in the case of children because there may be an increased risk of extra-pyramidal reactions in young children because of an incompletely developed blood-brain barrier. Since domperidone is highly metabolized in liver, it should be used with caution in patient with hepatic impairment.

Domperidone may reduce the risk of hypoprolactemic effect of bromocriptine. The action of Domperidone on Gl function may be antagonized by antimuscarinics and opoid analgesics. Care should be exercised when domperidone is administered in combination with MAO (monoamine oxidase) inhibitors.

The safety of domperidone has not been proven and it is therefore not recommended during pregnancy. Animal studies have not demonstrated the teratogenic effect in the fetus. Domperidone may precipitate galactorrhea and improve post-natal lactation. It is secreted in breast milk but in very small quantities insufficient to be considered harmful.

There are no reported cases of overdose.

Store below 30°C, Protected from light & moisture. Keep out of children's reach.

Motility Stimulants, Motility stimulants/Dopamine antagonist, Prokinetic drugs

Domperidone is a dopamine antagonist that principally blocks the dopamine receptors located in the ChemoreceptorTrigger Zone (CTZ) and stomach. Its gastroprokinetic action is based on its blocking effect of dopamine receptors that have an influence on the motility of the gastrointestinal tract. Due to its weak penetration across the blood-brain barrier, Domperidone has almost no effect on the dopaminergic receptors in the brain, therefore, excluding psychotropic and neurologic side effects. Domperidone restores normal motility and tone of the upper gastrointestinal tract, facilitates gastric emptying, enhances antral and duodenal peristalsis and regulates contraction of the pylorus. Domperidone also increases esophageal peristalsis and lower esophageal sphincter pressure, and thus prevents regurgitation of gastric content.

Domperidone should be taken 15-30 minutes before meals and, if necessary, before retiring.

The usual recommended oral dose of Domperidone is as follows:

• Adults: 10-20 mg (1-2 tablet or 10-20 ml suspension), every 6-8 hours daily. The maximum dose of Domperidone is 80 mg daily.
• Children: 2-4 ml suspension/10 kg body weight or 0.4-0.8 ml paediatric drops/10 kg body weight, every 6-8 hours daily.

In dyspeptic symptom:

• Adults: 10-20 mg (1-2 tablet or 10-20 ml suspension), every 6-8 hours daily.
• Children: 0.2-0.4 mg/kg (2-4 ml suspension/10 kg or 0.4-0.8 ml paediatric drops/10 kg) body weight, every 6-8 hours daily.

In acute and sub-acute conditions (mainly in acute nausea and vomiting):

• Adults: 20 mg (2 tablets or 20 ml suspension), every 6-8 hours daily
• Children: 0.2-0.4 mg/kg (2-4 ml suspension/10 kg or 0.4-0.8 ml paediatric drops/10 kg) body weight, every 6-8 hours daily. (In acute nausea and vomiting maximum period of treatment is 12 weeks).

By rectum in suppositories:

• Adults (including elderly): 30-60 mg every 4-8 hours.
• Children: The maximum daily dose rectally in children's is 30 mg for those weighting 10 to 25 kg. The dose may be divided throughout day if necessary.
• The maximum period of treatment is 12 weeks.

Rifaximin is indicaed in-

• Treatment of traveler's diarrhea by noninvasive strains of E. coli
• reduction in risk of overt hepatic encephalopathy
• bacterial overgrowth of irritable bowel syndrome.

4-Quinolone preparations

Rifaximin is a semisynthetic, rifamycin-based non-systemic antibiotic. Very little of the drug will pass the gastrointestinal wall into the circulation as is common for other types of orally administered antibiotics. Rifaximin inhibits bacterial RNA synthesis by its action on the beta-subunit of the DNA-dependent RNA polymerase. It shows the same broad spectrum activity as rifamycin which exerts bactericidal action against many species of Gram-positive and Gram-negative, aerobic and anaerobic bacteria.

Traveler's Diarrhea: For patients ≥12 years of age: 200 mg 3 times daily for 3 days.
Hepatic Encephalopathy: For patients ≥18 years of age: 550 mg 2 times daily.
Bacterial overgrowth of irritable bowel syndrome: 400 mg 3 times daily for 10 days or 550 mg 3 times daily for 14 days. Can be taken with or without food

Side effects include flatulence, headache, abdominal pain, rectal tenesmus, defecation urgency, nausea, constipation, pyrexia, vomiting. Reactions have been reported, including anaphylaxis, angioneurotic edema, and exfoliative dermatitis.

Contraindicated in patients with a hypersensitivity to Rifaximin or to any of the rifamycin antimicrobial agents, or any components of this product

Rifaximin is not found to be effective in patients with diarrhea complicated by fever and/or blood in the stools. Rifaximin therapy should be discontinued if diarrhea symptoms get worse or persist for more than 24-48 hours and alternative antibiotic therapy should be considered. Pseudomembranous colitis has been reported with nearly all antibacterial agents and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.

In an in vitro study has suggested that Rifaximin induces CYP3A4. However, in patients with normal liver function, Rifaximin at the recommended dosing regimen is not expected to induce CYP3A4.

Pregnancy category C. It is not known whether Rifaximin is excreted in human milk or not.

Renal Impairment: The pharmacokinetics of Rifaximin in patients with impaired renal function has not been studied.
Hepatic Impairment: The systemic exposure of Rifaximin was markedly elevated in patients with hepatic impairment compared to healthy subjects.

No specific information is available on the treatment of over dosage with Rifaximin. In case of over dosage, discontinue Rifaximin, treat symptomatically and institute supportive measures as required.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Rifampicin and Isoniazid belongs to a group of medicines called antituberculosis agents. It is a fixed combination of two very effective antituberculosis agents which stop the growth of mycobacteria. These mycobacteria cause tuberculosis. Rifampicin and Isoniazid is used for the continuation phase treatment of tuberculosis.

Combined anti- Tubercular Preparations

Rifampicin and isoniazid are active bactericidal anti-TB drugs which are particularly active against the rapidly growing extracellular organisms and also have bactericidal activity intracellularly. Rifampicin inhibits DNA-dependent RNA polymerase activity in susceptible cells. Specifically, it interacts with bacterial RNA polymerase but does not inhibit the mammalian enzyme. Cross-resistance to rifampicin has only been shown with other rifamycins. It has activity against slow-and intermittently-growing M. tuberculosis. Isoniazid acts against actively growing tubercle bacilli.

Body weight <50 kg: 3 tablet of 150/100 once daily or 1 tablet of 450/300 once daily
Body weight >50 kg: 2 tablet of 300/150 once daily.
Hepatic impairment: Max: 8 mg/kg daily.

Unwanted effects which may occur during continuous daily or intermittent therapy: Rifampicin: Rifampicin may cause reddish discolouration of body fluids and occasionally other body secretions eg, urine, sputum, lacrimal fluid, faeces, saliva and sweat. It may permanently discolour soft contact lenses.

Hepatic Effects: Very common (>10%) is an asymptomatic increase in liver enzymes; severe life-threatening hepatic reactions eg, hepatic failure and acute fulminant hepatitis are uncommon (>0.1% and <1%). In isolated cases (<0.01 %), a fatal outcome was observed.

Renal Effects: Elevations of BUN and serum uric acid, haemolysis, haematuria, interstitial nephritis, renal insufficiency. Gastrointestinal Effects: Nausea, abdominal pains, vomiting or diarrhoea, pseudomembranous colitis.

Central and Peripheral Nervous System Effects: Tiredness, drowsiness, headache, dizziness, ataxia, mental confusion, muscular weakness, visual disturbances. Haematological Changes: Leucopenia, eosinophilia, thrombocytopenia and thrombocytopenic purpura. Effects on Skin and Appendages: Flushing, itching with or without skin rash, urticaria, reddening of the eyes, exudative conjunctivitis or generalised hypersensitivity reactions involving the skin eg, exfoliative dermatitis, Lyell's syndrome and pemphigoid reactions. Endocrine Effects: Disturbances in the menstrual cycle, induction of crisis in Addison patients. Unwanted effects chiefly occurring during intermittent therapy or upon resumption of treatment after temporary interruption

Known or suspected hypersensitivity to rifamycins and/or to INH, and/or to any of the excipients including a history of drug-induced hepatitis; acute liver diseases, regardless of their origin; peripheral neuritis.

Use of isoniazid should be carefully monitored in the following:

• Daily users of alcohol. Daily ingestion of alcohol may be associated with a higher incidence of isoniazid hepatitis.
• Patients with active chronic liver disease or severe renal dysfunction.
• Age >35.
• Concurrent use of any chronically administered medication.
• History of previous discontinuation of isoniazid.
• Existence of peripheral neuropathy or conditions predisposing to neuropathy. Pregnancy.
• Injection drug use.
• Women belonging to minority groups, particularly in the post-partum period.
• HIV seropositive patients.

May reduce effectivity of hormonal contraceptives. Reduced absorption with antacids. May decrease plasma concentrations of antivirals (e.g. atazanavir, darunavir, fosamprenavir), atovaquone with rifampicin. Rifampicin may reduce serum levels of anticonvulsants (e.g. phenytoin), antiarrhythmics (e.g. disopyramide), oral anticoagulants, antifungals (e.g. ketoconazole), barbiturates, ?-blockers, Ca channel blockers (e.g. diltiazem), chloramphenicol, clarithromycin, corticosteroids, ciclosporin, cardiac glycosides, clofibrate, dapsone, diazepam, doxycycline, fluoroquinolones (e.g. ciprofloxacin), haloperidol, oral hypoglycemic agents (sulfonylureas), levothyroxine, methadone, narcotic analgesics, progestins, quinine, tacrolimus, theophylline, TCAs (e.g. amitriptyline, nortriptyline) and zidovudine. Increased risk of hepatotoxicity with halothane.

Isoniazid may inhibit the metabolism of anticonvulsants (e.g. carbamazepine, phenytoin), benzodiazepines (e.g. diazepam), haloperidol, ketoconazole, theophylline, and warfarin. May enhance the CNS effects of meperidine, cycloserine, and disulfiram with isoniazid. Loss of glucose control in patients on oral hypoglycaemics with isoniazid.

Pregnancy Category C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks

Anti-Tubercular Antibiotics

Rifampicin suppresses initiation of chain formation for RNA synthesis in susceptible bacteria by binding to the β subunit of DNA-dependent RNA polymerase, thus blocking RNA transcription.

Rifampin can be administered by the oral route or by IV infusion. IV doses are the same as those for oral.

Tuberculosis:

• Adults: 10 mg/kg, in a single daily administration, not to exceed 600 mg/day, oral or IV
• Pediatric Patients: 10–20 mg/kg, not to exceed 600 mg/day, oral or IV

It is recommended that oral rifampin be administered once daily, either 1 hour before or 2 hours after a meal with a full glass of water.

Rifampin is indicated in the treatment of all forms of tuberculosis. A three-drug regimen consisting of rifampin, isoniazid, and pyrazinamide is recommended in the initial phase of shortcourse therapy which is usually continued for 2 months. The Advisory Council for the Elimination of Tuberculosis, the American Thoracic Society, and the Centers for Disease Control and Prevention recommend that either streptomycin or ethambutol be added as a fourth drug in a regimen containing isoniazid (INH), rifampin and pyrazinamide for initial treatment of tuberculosis unless the likelihood of INH resistance is very low. The need for a fourth drug should be reassessed when the results of susceptibility testing are known. If community rates of INH resistance are currently less than 4%, an initial treatment regimen with less than four drugs may be considered.

Following the initial phase, treatment should be continued with rifampin and isoniazid for at least 4 months. Treatment should be continued for longer if the patient is still sputum or culture positive, if resistant organisms are present, or if the patient is HIV positive.

Should be taken on an empty stomach. Best taken on an empty stomach 1 hr before or 2 hr after meals.

Facial flushing and itching, with or without a rash, flu-like syndrome characterised by episodes of fever, chills, headache, dizziness, bone pain, shortness of breath, and malaise; GI adverse effects (e.g. nausea, vomiting, anorexia, diarrhoea, epigastric distress), pseudomembranous colitis, eosinophilia, leucopenia, haemolytic anaemia; alterations in kidney function and renal failure, menstrual disturbances, oedema, myopathy, muscular weakness; orange-red discolouration of the urine, faeces, sweat, saliva, sputum, tears, and other body fluids; thrombophlebitis, local irritation and inflammation after prolonged IV infusion. Rarely, eye irritation and visual disturbances, anaphylaxis or shock.

Rifampicin is contraindicated in patients with a history of hypersensitivity to rifampin or any of the components, or to any of the rifamycins. Rifampin is contraindicated in patients who are also receiving ritonavir-boosted saquinavir due to an increased risk of severe hepatocellular toxicity.

Rifampin is contraindicated in patients who are also receiving atazanavir, darunavir, fosamprenavir, saquinavir, or tipranavir due to the potential of rifampin to substantially decrease plasma concentrations of these antiviral drugs, which may result in loss of antiviral efficacy and/or development of viral resistance.

Rifampicin has been shown to produce liver dysfunction. Fatalities associated with jaundice have occurred in patients with liver disease and in patients taking rifampin with other hepatotoxic agents. Patients with impaired liver function should be given rifampin only in cases of necessity and then with caution and under strict medical supervision. In these patients, careful monitoring of liver function, especially SGPT/ALT and SGOT/AST should be carried out prior to therapy and then every 2 to 4 weeks during therapy. If signs of hepatocellular damage occur, rifampin should be withdrawn.

In some cases, hyperbilirubinemia resulting from competition between rifampin and bilirubin for excretory pathways of the liver at the cell level can occur in the early days of treatment. An isolated report showing a moderate rise in bilirubin and/or transaminase level is not in itself an indication for interrupting treatment; rather, the decision should be made after repeating the tests, noting trends in the levels, and considering them in conjunction with the patient's clinical condition.

Rifampin has enzyme-inducing properties, including induction of delta amino levulinic acid synthetase. Isolated reports have associated porphyria exacerbation with rifampin administration.

May accelerate the metabolism and reduce the effect of drugs that are metabolised by CYP450 enzymes (e.g. quinidine, phenytoin, theophylline). Decreased concentrations of atovaquone and increased concentrations of rifampicin when taken concomitantly. Concurrent use of ketoconazole and rifampicin may result in decreased serum concentrations of both drugs. May decrease serum concentrations of enalaprilat. Reduced absorption by antacids. Increased risk of hepatotoxicity with halothane or isoniazid.

Pregnancy: When administered during the last few weeks of pregnancy, rifampin can cause post natal hemorrhages in the mother and infant for which treatment with vitamin K may be indicated.

Nursing Mothers: Because of the potential for tumorigenicity shown for rifampin in animal studies, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Geriatric Use: Clinical studies of Rifampicin did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Caution should therefore be observed in using rifampin in elderly patients.

Nausea, vomiting, abdominal pain, pruritus, headache, and increasing lethargy will probably occur within a short time after ingestion; unconsciousness may occur when there is severe hepatic disease. Transient increases in liver enzymes and/or bilirubin may occur. Brownish-red or orange discoloration of the skin, urine, sweat, saliva, tears, and feces will occur, and its intensity is proportional to the amount ingested.

Liver enlargement, possibly with tenderness, can develop within a few hours after severe overdosage; bilirubin levels may increase and jaundice may develop rapidly. Hepatic involvement may be more marked in patients with prior impairment of hepatic function. Other physical findings remain essentially normal. A direct effect upon the hematopoietic system, electrolyte levels, or acid-base balance is unlikely.

Facial or periorbital edema has also been reported in pediatric patients. Hypotension, sinus tachycardia, ventricular arrhythmias, seizures and cardiac arrest were reported in some fatal cases.

Preparation Of Solution For IV Infusion: Reconstitute the lyophilized powder by transferring 10 mL of sterile water for injection to a vial containing 600 mg of rifampin for injection. Swirl vial gently to completely dissolve the antibiotic. The reconstituted solution contains 60 mg rifampin per mL and is stable at room temperature for up to 30 hours. Prior to administration, withdraw from the reconstituted solution a volume equivalent to the amount of rifampin calculated to be administered and add to 500 mL of infusion medium. Mix well and infuse at a rate allowing for complete infusion within 3 hours. Alternatively, the amount of rifampin calculated to be administered may be added to 100 mL of infusion medium and infused in 30 minutes.

Dilutions in dextrose 5% for injection (D5W) are stable at room temperature for up to 8 hours and should be prepared and used within this time. Precipitation of rifampin from the infusion solution may occur beyond this time. Dilutions in normal saline are stable at room temperature for up to 6 hours and should be prepared and used within this time. Other infusion solutions are not recommended.

Store between 15-30° C. Avoid excessive heat and protect from light.
