Proton Pump Inhibitor
PharmacologyView
Omeprazole, a substituted benzimidazole, is an inhibitor of gastric acid secretion. It inhibits gastric acid secretion by blocking hydrogen-potassium-adenosine triphosphatase (H+/K+ ATPase) enzyme system in the gastric parietal cell. After oral administration, the onset of the antisecretory effect occurs within one hour, with the maximum effect occurring within two hours and inhibition of secretion lasts up to 72 hours. When the drug is discontinued, secretory activity returns gradually, over 3 to 5 days.

AdministrationView
Direction for use of IV Injection: Omeprazole lyophilized powder and water for injection is for intravenous administration only and must not be given by any other route. Omeprazole IV injection should be given as a slow intravenous injection. The solution for IV injection is obtained by adding 10 ml water for injection to the vial containing powder. After reconstitution the injection should be given slowly over a period of at least 2 to 5 minutes at a maximum rate of 4 ml/minute. Use only freshly prepared solution. The solution should be used within 4 hours of reconstitution.
Direction for use of IV Infusion: Omeprazole IV infusion should be given as an intravenous infusion over a period of 20-30 minutes or more. The contents of one vial must be dissolved in 100 ml saline for infusion or 100 ml 5% Dextrose for infusion. The solution should be used within 12 hours when Omeprazole is dissolved in saline and within 6 hours when dissolved in 5% Dextrose. The reconstituted solution should not be mixed or co-administered in the same infusion set with any other drug.

The reconstituted solution should not be mixed or co-administered in the same infusion set with any other drug.
Side effectsView
Omeprazole is generally well tolerated. Nausea, abdominal colic, paresthesia, dizziness and headache have been stated to be generally mild and transient and not requiring a reduction in dosage.
ContraindicationsView
Omeprazole is contraindicated in patients with known hypersensitivity to any of the components of the formulation.
PrecautionsView
When gastric ulcer is suspected, the possibility of gastric malignancy should be excluded before treatment with Omeprazole is instituted, as treatment may alleviate the symptoms and delay diagnosis.
InteractionsView
Omeprazole can prolong the elimination of diazepam, warfarin and phenytoin. So, reduction of warfarin or phenytoin dose may be necessary when Omeprazole is added to the treatment. There is no evidence of an interaction of Omeprazole with theophylline, propranolol or antacids.
Pregnancy & lactationView
US FDA pregnancy category of Omeprazole is C. However, results from three prospective epidemiological studies indicate no adverse effects of Omeprazole on pregnancy or on the health of the fetus/newborn child. There is no information available on the passage of Omeprazole into breast milk or its effects on the neonate. Breast-feeding should, therefore, be discontinued, if the use of Omeprazole is considered essential.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

Ondansetron
Indications
Post-operative nausea and vomiting
Indication detailsView
Ondansetron is a serotonin subtype 3 (5-HT3) receptor antagonist indicated:
- Prevention of nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy.
- Prevention and treatment of post-operative nausea and vomiting.
- Prevention of radiotherapy-induced nausea and vomiting.
Therapeutic classView
Anti-emetic drugs
PharmacologyView
Ondansetron is a potent, highly selective 5HT3 receptor-antagonist. Its precise mode of action in the control of nausea and vomiting is not known. Chemotherapeutic agents and radiotherapy may cause release of 5HT in the small intestine initiating a vomiting reflex by activating vagal afferents via 5HT3 receptors. Ondansetron blocks the initiation of this reflex. Activation of vagal afferents may also cause a release of 5HT in the area postrema, located on the floor of the fourth ventricle, and this may also promote emesis through a central mechanism. Thus, the effect of ondansetron in the management of the nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy is probably due to antagonism of 5HT3 receptors on neurons located both in the peripheral and central nervous system. The mechanisms of action in post-operative nausea and vomiting are not known but there may be common pathways with cytotoxic induced nausea and vomiting.

Side effectsView
Frequently reported adverse events were headache, constipation and diarrhea, but the majority have been mild or moderate in nature. In chemotherapy-induced nausea and vomiting, rash has occurred in approximately 1% of patients receiving Ondansetron. There also have been reports to a sensation of flushing or warmth, hiccups and liver enzyme abnormalities. Rare cases of anaphylaxis, brochospasm, tachycardia, angina (chest pain), hypokalemia, shortness of breath have also been reported, except for bronchospasm and anaphylaxis, the relationship to Ondansetron is unclear. There have been no evidence to extrapyramidal reactions, in rare case oculogyric crisis appearing alone, as well as with other dystonic reactions without definitive clinical evidence. In case of PONV, with the exception of headache, rates of these events were not significantly different in the Ondansetron and placebo groups.
ContraindicationsView
Contraindicated in patients known to have hypersensitivity to the drug or any of its components. Concomitant use of apomorphine.
PrecautionsView
Hypersensitivity reactions have been reported in patients who have exhibited hypersensitivity to other selective 5-HT3 receptor antagonists. Ondansetron is not a drug that stimulates gastric or intestinal peristalsis. It should not be used instead of nasogastric suction. The use of Ondansetron in patients following abdominal surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and/or gastric distension.
InteractionsView
Ondansetron does not itself appear to induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system of the liver. Because Ondansetron is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and hence, the half-life of Ondansetron. On the basis of available data, no dosage adjustment of Ondasetron is recommended for patients on these drugs.
Pregnancy & lactationView
Carcinogenic effects were not seen in 2-year studies in rats and mice with oral Ondansetron doses up to 10 and 30 mg/kg per day, respectively. Ondansetron was not mutagenic in standard tests for mutagenicity. Oral administration of Ondansetron up to 15 mg/kg per day did not affect fertility or general reproduction performance of male and female rats.
Reproduction studies have been performed in pregnant rats and rabbits at daily oral doses up to 15 and 30 mg/kg per day, respectively, and have revealed no evidence of impaired fertility or harm to the fetus due to Ondansetron. There are, however, no adequate and well-controlled studies in pregnant women. Ondansetron is excreted in the breast milk of rats. So caution should be exercised when Ondansetron is administered to a nursing women.

Indications
Post-operative nausea and vomiting
Indication detailsView
Ondansetron is a serotonin subtype 3 (5-HT3) receptor antagonist indicated:
- Prevention of nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy.
- Prevention and treatment of post-operative nausea and vomiting.
- Prevention of radiotherapy-induced nausea and vomiting.
Therapeutic classView
Anti-emetic drugs
PharmacologyView
Ondansetron is a potent, highly selective 5HT3 receptor-antagonist. Its precise mode of action in the control of nausea and vomiting is not known. Chemotherapeutic agents and radiotherapy may cause release of 5HT in the small intestine initiating a vomiting reflex by activating vagal afferents via 5HT3 receptors. Ondansetron blocks the initiation of this reflex. Activation of vagal afferents may also cause a release of 5HT in the area postrema, located on the floor of the fourth ventricle, and this may also promote emesis through a central mechanism. Thus, the effect of ondansetron in the management of the nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy is probably due to antagonism of 5HT3 receptors on neurons located both in the peripheral and central nervous system. The mechanisms of action in post-operative nausea and vomiting are not known but there may be common pathways with cytotoxic induced nausea and vomiting.

Side effectsView
Frequently reported adverse events were headache, constipation and diarrhea, but the majority have been mild or moderate in nature. In chemotherapy-induced nausea and vomiting, rash has occurred in approximately 1% of patients receiving Ondansetron. There also have been reports to a sensation of flushing or warmth, hiccups and liver enzyme abnormalities. Rare cases of anaphylaxis, brochospasm, tachycardia, angina (chest pain), hypokalemia, shortness of breath have also been reported, except for bronchospasm and anaphylaxis, the relationship to Ondansetron is unclear. There have been no evidence to extrapyramidal reactions, in rare case oculogyric crisis appearing alone, as well as with other dystonic reactions without definitive clinical evidence. In case of PONV, with the exception of headache, rates of these events were not significantly different in the Ondansetron and placebo groups.
ContraindicationsView
Contraindicated in patients known to have hypersensitivity to the drug or any of its components. Concomitant use of apomorphine.
PrecautionsView
Hypersensitivity reactions have been reported in patients who have exhibited hypersensitivity to other selective 5-HT3 receptor antagonists. Ondansetron is not a drug that stimulates gastric or intestinal peristalsis. It should not be used instead of nasogastric suction. The use of Ondansetron in patients following abdominal surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and/or gastric distension.
InteractionsView
Ondansetron does not itself appear to induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system of the liver. Because Ondansetron is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and hence, the half-life of Ondansetron. On the basis of available data, no dosage adjustment of Ondasetron is recommended for patients on these drugs.
Pregnancy & lactationView
Carcinogenic effects were not seen in 2-year studies in rats and mice with oral Ondansetron doses up to 10 and 30 mg/kg per day, respectively. Ondansetron was not mutagenic in standard tests for mutagenicity. Oral administration of Ondansetron up to 15 mg/kg per day did not affect fertility or general reproduction performance of male and female rats.
Reproduction studies have been performed in pregnant rats and rabbits at daily oral doses up to 15 and 30 mg/kg per day, respectively, and have revealed no evidence of impaired fertility or harm to the fetus due to Ondansetron. There are, however, no adequate and well-controlled studies in pregnant women. Ondansetron is excreted in the breast milk of rats. So caution should be exercised when Ondansetron is administered to a nursing women.

Side effectsView
Frequently reported adverse events were headache, constipation and diarrhea, but the majority have been mild or moderate in nature. In chemotherapy-induced nausea and vomiting, rash has occurred in approximately 1% of patients receiving Ondansetron. There also have been reports to a sensation of flushing or warmth, hiccups and liver enzyme abnormalities. Rare cases of anaphylaxis, brochospasm, tachycardia, angina (chest pain), hypokalemia, shortness of breath have also been reported, except for bronchospasm and anaphylaxis, the relationship to Ondansetron is unclear. There have been no evidence to extrapyramidal reactions, in rare case oculogyric crisis appearing alone, as well as with other dystonic reactions without definitive clinical evidence. In case of PONV, with the exception of headache, rates of these events were not significantly different in the Ondansetron and placebo groups.
ContraindicationsView
Contraindicated in patients known to have hypersensitivity to the drug or any of its components. Concomitant use of apomorphine.
PrecautionsView
Hypersensitivity reactions have been reported in patients who have exhibited hypersensitivity to other selective 5-HT3 receptor antagonists. Ondansetron is not a drug that stimulates gastric or intestinal peristalsis. It should not be used instead of nasogastric suction. The use of Ondansetron in patients following abdominal surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and/or gastric distension.
InteractionsView
Ondansetron does not itself appear to induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system of the liver. Because Ondansetron is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and hence, the half-life of Ondansetron. On the basis of available data, no dosage adjustment of Ondasetron is recommended for patients on these drugs.
Pregnancy & lactationView
Carcinogenic effects were not seen in 2-year studies in rats and mice with oral Ondansetron doses up to 10 and 30 mg/kg per day, respectively. Ondansetron was not mutagenic in standard tests for mutagenicity. Oral administration of Ondansetron up to 15 mg/kg per day did not affect fertility or general reproduction performance of male and female rats.
Reproduction studies have been performed in pregnant rats and rabbits at daily oral doses up to 15 and 30 mg/kg per day, respectively, and have revealed no evidence of impaired fertility or harm to the fetus due to Ondansetron. There are, however, no adequate and well-controlled studies in pregnant women. Ondansetron is excreted in the breast milk of rats. So caution should be exercised when Ondansetron is administered to a nursing women.

Indications
Post-operative nausea and vomiting
Indication detailsView
Ondansetron is a serotonin subtype 3 (5-HT3) receptor antagonist indicated:
- Prevention of nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy.
- Prevention and treatment of post-operative nausea and vomiting.
- Prevention of radiotherapy-induced nausea and vomiting.
Therapeutic classView
Anti-emetic drugs
PharmacologyView
Ondansetron is a potent, highly selective 5HT3 receptor-antagonist. Its precise mode of action in the control of nausea and vomiting is not known. Chemotherapeutic agents and radiotherapy may cause release of 5HT in the small intestine initiating a vomiting reflex by activating vagal afferents via 5HT3 receptors. Ondansetron blocks the initiation of this reflex. Activation of vagal afferents may also cause a release of 5HT in the area postrema, located on the floor of the fourth ventricle, and this may also promote emesis through a central mechanism. Thus, the effect of ondansetron in the management of the nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy is probably due to antagonism of 5HT3 receptors on neurons located both in the peripheral and central nervous system. The mechanisms of action in post-operative nausea and vomiting are not known but there may be common pathways with cytotoxic induced nausea and vomiting.

Side effectsView
Frequently reported adverse events were headache, constipation and diarrhea, but the majority have been mild or moderate in nature. In chemotherapy-induced nausea and vomiting, rash has occurred in approximately 1% of patients receiving Ondansetron. There also have been reports to a sensation of flushing or warmth, hiccups and liver enzyme abnormalities. Rare cases of anaphylaxis, brochospasm, tachycardia, angina (chest pain), hypokalemia, shortness of breath have also been reported, except for bronchospasm and anaphylaxis, the relationship to Ondansetron is unclear. There have been no evidence to extrapyramidal reactions, in rare case oculogyric crisis appearing alone, as well as with other dystonic reactions without definitive clinical evidence. In case of PONV, with the exception of headache, rates of these events were not significantly different in the Ondansetron and placebo groups.
ContraindicationsView
Contraindicated in patients known to have hypersensitivity to the drug or any of its components. Concomitant use of apomorphine.
PrecautionsView
Hypersensitivity reactions have been reported in patients who have exhibited hypersensitivity to other selective 5-HT3 receptor antagonists. Ondansetron is not a drug that stimulates gastric or intestinal peristalsis. It should not be used instead of nasogastric suction. The use of Ondansetron in patients following abdominal surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and/or gastric distension.
InteractionsView
Ondansetron does not itself appear to induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system of the liver. Because Ondansetron is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and hence, the half-life of Ondansetron. On the basis of available data, no dosage adjustment of Ondasetron is recommended for patients on these drugs.
Pregnancy & lactationView
Carcinogenic effects were not seen in 2-year studies in rats and mice with oral Ondansetron doses up to 10 and 30 mg/kg per day, respectively. Ondansetron was not mutagenic in standard tests for mutagenicity. Oral administration of Ondansetron up to 15 mg/kg per day did not affect fertility or general reproduction performance of male and female rats.
Reproduction studies have been performed in pregnant rats and rabbits at daily oral doses up to 15 and 30 mg/kg per day, respectively, and have revealed no evidence of impaired fertility or harm to the fetus due to Ondansetron. There are, however, no adequate and well-controlled studies in pregnant women. Ondansetron is excreted in the breast milk of rats. So caution should be exercised when Ondansetron is administered to a nursing women.

Indications
Post-operative nausea and vomiting
Indication detailsView
Ondansetron is a serotonin subtype 3 (5-HT3) receptor antagonist indicated:
- Prevention of nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy.
- Prevention and treatment of post-operative nausea and vomiting.
- Prevention of radiotherapy-induced nausea and vomiting.
Therapeutic classView
Anti-emetic drugs
PharmacologyView
Ondansetron is a potent, highly selective 5HT3 receptor-antagonist. Its precise mode of action in the control of nausea and vomiting is not known. Chemotherapeutic agents and radiotherapy may cause release of 5HT in the small intestine initiating a vomiting reflex by activating vagal afferents via 5HT3 receptors. Ondansetron blocks the initiation of this reflex. Activation of vagal afferents may also cause a release of 5HT in the area postrema, located on the floor of the fourth ventricle, and this may also promote emesis through a central mechanism. Thus, the effect of ondansetron in the management of the nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy is probably due to antagonism of 5HT3 receptors on neurons located both in the peripheral and central nervous system. The mechanisms of action in post-operative nausea and vomiting are not known but there may be common pathways with cytotoxic induced nausea and vomiting.

Onbrez Breezhaler
Indacaterol Maleate
Indications
COPD
Indication detailsView
Indacaterol is indicated for the treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema.
Therapeutic classView
Long-acting selective β-adrenoceptor stimulants
DosageView
Indacaterol capsules must not be swallowed as the intended effects on the lungs will not be obtained. The contents of Indacaterol capsules are only for oral inhalation and should only be used with the device.
The recommended dosage of Indacaterol is the once-daily inhalation of the contents of one 75 mcg, 150 mcg, 300 mcg Indacaterol capsule using the device.
Indacaterol should be administered once daily every day at the same time of the day by the orally inhaled route only. If a dose is missed, the next dose should be taken as soon as it is remembered. Do not use Indacaterol more than one time every 24 hours.
No dosage adjustment is required for geriatric patients, patients with mild and moderate hepatic impairment, or renally impaired patients. No data are available for subjects with severe hepatic impairment. Indacaterol is not indicated for use in the pediatric population. Safety and efficacy have not been established.

Side effectsView
The most commonly reported adverse effects were cough, nasopharyngitis, headache, nausea, oropharyngeal pain. Some other also reported of hypersensitivity reactions, paradoxical bronchospasm, tachycardia, pruritis and dizziness.
ContraindicationsView
All LABA are contraindicated in patients with asthma without use of a long-term asthma control medication. Indacaterol powder is not indicated for the treatment of asthma. Indacaterol is contraindicated in patients with a history of hypersensitivity to Indacaterol or to any of the ingredients.
PrecautionsView
Rarely, serious (sometimes fatal) breathing problems have happened to people with asthma using a long-acting inhaled beta agonist (salmeterol). Since Indacaterol is similar to salmeterol, it might cause these serious breathing problems. Indacaterol has not been shown to be safe or effective to treat asthma and is not approved for this use.
InteractionsView
Indacaterol shows interaction with Adrenergic Drugs, Xanthine Derivatives, Steroids, or Diuretics. Concomitant treatment with xanthine derivatives, steroids, or diuretics may potentiate any hypokalemic effect of Indacaterol. The ECG changes or hypokalemia that may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by β2-agonists. Indacaterol, as with other β2-agonists, should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors, tricyclic antidepressants, or other drugs known to prolong the QTc interval. β-adrenergic receptor antagonists (beta-blockers) and Indacaterol may interfere with the effect of each other when administered concurrently.
Pregnancy & lactationView
Pregnancy Category C. There are no adequate and well-controlled studies with Indacaterol powder in pregnant women. Indacaterol powder should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known that the active component of Indacaterol powder, Indacaterol is excreted in human milk. Because many drugs are excreted in human milk and because Indacaterol has been detected in the milk of lactating rats, caution should be exercised when Indacaterol powder is administered to nursing women.
Overdose effectsView
The expected signs and symptoms associated with over dosage of Indacaterol powder are those of excessive beta-adrenergic stimulation and occurrence or exaggeration of any of the signs and symptoms, e.g., angina, hypertension or hypotension, tachycardia, with rates up to 200 bpm, arrhythmias, nervousness, headache, tremor, dry mouth, palpitation, muscle cramps, nausea, dizziness, fatigue, malaise, hypokalemia, hyperglycemia, metabolic acidosis and insomnia. As with all inhaled sympathomimetic medications, cardiac arrest and even death may be associated with an over dose of Indacaterol powder.
StorageView
Indacaterol capsules must always be stored in the blister, and only removed immediately before use. Keep in a cool & dry place. Keep out of the reach of children.

Amoxicillin + Clavulanic Acid
Indications
Severe or recurrent respiratory tract infections
Indication detailsView
Co-amoxiclav is indicated for short-term treatment of bacterial infections at the following sites:
- Upper respiratory tract infections (including ENT) e.g.tonsillitis,sinusitis,otitis media.
- Lower respiratory tract infections e.g.acute and chronic bronchitis, lobar and bronchopneumonia.
- Genito-urinary tract infections e.g.cystitis,urethritis,pyelonephritis.
- Skin and soft tissue infections.
- Bone and joint infections e.g.osteomyelitis.
- Other infections e.g.septic abortion,puerperal sepsis,intra-abdominal sepsis etc.
Therapeutic classView
Broad spectrum penicillins
PharmacologyView
Pharmacodynamic properties: Co-amoxiclav is an antibacterial combination consisting of the antibiotic Amoxicillin and the (3-lactamase inhibitor Clavulanic Acid. Amoxicillin has a broad spectrum of bactericidal activity against many Gram-positive & Gram-negative microorganisms but it is susceptible to degradation by (3-lactamases and therefore the spectrum of activity does not include microorganisms, which produce these enzymes. Clavulanic acid possesses the ability to inactivate a wide range of beta-lactamase enzymes commonly found in microorganisms resistant to penicillins and cephalosporins. Thus Clavulanic acid in this preparation protects Amoxicillin from degradation by (3-lactamase enzymes and effectively extends the antibiotic spectrum to embrace a wide range of microorganisms.
Pharmacokinetic properties: The pharmacokinetics of the two components of Co-amoxiclav is closely matched. Peak serum levels of both occur about one hour after oral administration. Absorption of Co-amoxiclav is optimized at the start of a meal. Both clavulanate and Amoxicillin have low levels of serum binding; about 70% remains free in the serum. Doubling the dosage of Co-amoxiclav approximately doubles the serum levels achieved.

AdministrationView
Oral dosage form: This may be taken without regard to meals; however, absorption of clavulanate potassium is enhanced when Amoxicillin and Clavulanic acid are administered at the start of a meal. To minimize the potential for gastrointestinal intolerance, Amoxicillin and Clavulanic acid should be taken at the start of the meal.
IV injection is not suitable for intramuscular or subcutaneous administration. The reconstituted vial can be administered intravenously by injection (over 2 minutes) or slow intravenous infusion (30 minutes). The contents of the content of the vial must be used within 20 minutes and thereafter any unused material should be discarded.

The contents of the content of the vial must be used within 20 minutes and thereafter any unused material should be discarded.
Side effectsView
Side effects, as with Amoxicillin, are uncommon and mainly of a mild and transitory nature. Diarrhoea, pseudomembranous colitis, indigestion, nausea, vomiting and candidiasis have been reported, if gastrointestinal side effects occur with oral therapy, that may be reduced by taking Co-amoxiclav at the start of meals. Hepatitis and cholestatic jaundice have been reported rarely but are usually reversible. Urticarial and erythematous rashes sometimes occur. Rarely erythema multiforme, Stevens-Johnson Syndrome and exfoliative dermatitis have been reported. In common with other beta-lactam antibiotics, angioedema and anaphylaxis have been reported.
ContraindicationsView
History of Penicillin hypersensitivity. Attention should be paid to possible cross-sensitivity with other beta-lactam antibiotics e.g. cephalosporins. Also contraindicated for patients with a previous history of Co-amoxiclav or Penicillin-associated cholestatic jaundice.
PrecautionsView
Co-amoxiclav should be used with care in patients on anticoagulation therapy or with severe hepatic dysfunction. In patients with moderate or severe renal impairment, dosage should be adjusted. During the administration of a high dose of Co-amoxiclav adequate fluid intake and urinary output should be maintained to minimize the possibility of crystalluria.
InteractionsView
Prolongation of bleeding time and prothrombin time have been reported in some patients receiving Co-amoxiclav. In common with other broad-spectrum antibiotics, Co-amoxiclav may reduce the efficacy of oral contraceptives and patients should be warned accordingly. Concomitant use of allopurinol during treatment with amoxicillin can increase the likelihood of allergic skin reactions. There are no data on the concomitant use of Co-amoxiclav and allopurinol.
Pregnancy & lactationView
Animal studies with orally and parenterally administered Co-amoxiclav have shown no teratogenic effect. The drug has been used orally in human pregnancy in a limited number of cases with no untoward effect; however, the use of Co-amoxiclav in pregnancy is not recommended unless considered essential by the physician. During lactation, trace quantities of Amoxicillin can be detected in breast milk.
Pediatric usageView
The dose should be adjusted in case of patients with renal impairment
Adult:
Adult:
- Mild impairment (Creatinine clearance> 30ml/minute): No changein dosage.
- Moderate impairment (Creatinine clearance 10-30 ml/minute): One 375 Tablet or one 625 Tablet 12 hourly or 1.2 gm IV followed by 0.6 gm IV 12 hourly.
- Severe impairment (Creatinine clearance <10 ml/minute): Not more than one 375 mg tablet 12 hourly or 1.2 gm IV followed by 0.6 gm IV 24 hourly. Dialysis decreases serum concentrations of this preparation and an additional 0.6 gm IV dose may need to be given during dialysis and at the end of dialysis.
- A similar reduction in dosage should be made for children.
- Administration hepatic impairment: Dose with caution; monitor hepatic function at regular intervals.
Overdose effectsView
Problems of overdose with Co-amoxiclav are unlikely to occur, if encountered gastrointestinal symptoms and disturbance of the fluid and electrolyte balances may be evident. Co-amoxiclav may be removed from the circulation by haemodialysis.
ReconstitutionView
IV injection: 1.2 gm IV injection can be reconstituted by dissolving the powder in 20 ml Water for Injection BP. This IV injection should not be reconstituted or mixed with: Dextrose solution, Sodium Bicarbonate solution for injection, Protein Hydrolysates or other Proteinaceous fluids, blood or plasma, Intravenous lipids. However, the reconstituted solution may be injected into the drip tubing of infusion fluids containing glucose, bicarbonate and dextran over a period of 3-4 minutes.
StorageView
This should be stored below 25°C, protected from light and moisture. Once reconstituted suspension should be kept in the refrigerator (but not frozen) and should be usedby 7 days. Once reconstituted vial must be used within 20 minutes.

Therapeutic classView
Broad spectrum penicillins
PharmacologyView
Pharmacodynamic properties: Co-amoxiclav is an antibacterial combination consisting of the antibiotic Amoxicillin and the (3-lactamase inhibitor Clavulanic Acid. Amoxicillin has a broad spectrum of bactericidal activity against many Gram-positive & Gram-negative microorganisms but it is susceptible to degradation by (3-lactamases and therefore the spectrum of activity does not include microorganisms, which produce these enzymes. Clavulanic acid possesses the ability to inactivate a wide range of beta-lactamase enzymes commonly found in microorganisms resistant to penicillins and cephalosporins. Thus Clavulanic acid in this preparation protects Amoxicillin from degradation by (3-lactamase enzymes and effectively extends the antibiotic spectrum to embrace a wide range of microorganisms.
Pharmacokinetic properties: The pharmacokinetics of the two components of Co-amoxiclav is closely matched. Peak serum levels of both occur about one hour after oral administration. Absorption of Co-amoxiclav is optimized at the start of a meal. Both clavulanate and Amoxicillin have low levels of serum binding; about 70% remains free in the serum. Doubling the dosage of Co-amoxiclav approximately doubles the serum levels achieved.

Ondansetron
Indications
Post-operative nausea and vomiting
Indication detailsView
Ondansetron is a serotonin subtype 3 (5-HT3) receptor antagonist indicated:
- Prevention of nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy.
- Prevention and treatment of post-operative nausea and vomiting.
- Prevention of radiotherapy-induced nausea and vomiting.
Therapeutic classView
Anti-emetic drugs
PharmacologyView
Ondansetron is a potent, highly selective 5HT3 receptor-antagonist. Its precise mode of action in the control of nausea and vomiting is not known. Chemotherapeutic agents and radiotherapy may cause release of 5HT in the small intestine initiating a vomiting reflex by activating vagal afferents via 5HT3 receptors. Ondansetron blocks the initiation of this reflex. Activation of vagal afferents may also cause a release of 5HT in the area postrema, located on the floor of the fourth ventricle, and this may also promote emesis through a central mechanism. Thus, the effect of ondansetron in the management of the nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy is probably due to antagonism of 5HT3 receptors on neurons located both in the peripheral and central nervous system. The mechanisms of action in post-operative nausea and vomiting are not known but there may be common pathways with cytotoxic induced nausea and vomiting.

- Step 4: Swallow after the Onsaf oral soluble film dissolves. You may swallow the dissolved film with or without liquid.
- Step 5: Wash your hands after taking Onsaf oral soluble film
Side effectsView
Frequently reported adverse events were headache, constipation and diarrhea, but the majority have been mild or moderate in nature. In chemotherapy-induced nausea and vomiting, rash has occurred in approximately 1% of patients receiving Ondansetron. There also have been reports to a sensation of flushing or warmth, hiccups and liver enzyme abnormalities. Rare cases of anaphylaxis, brochospasm, tachycardia, angina (chest pain), hypokalemia, shortness of breath have also been reported, except for bronchospasm and anaphylaxis, the relationship to Ondansetron is unclear. There have been no evidence to extrapyramidal reactions, in rare case oculogyric crisis appearing alone, as well as with other dystonic reactions without definitive clinical evidence. In case of PONV, with the exception of headache, rates of these events were not significantly different in the Ondansetron and placebo groups.
ContraindicationsView
Contraindicated in patients known to have hypersensitivity to the drug or any of its components. Concomitant use of apomorphine.
PrecautionsView
Hypersensitivity reactions have been reported in patients who have exhibited hypersensitivity to other selective 5-HT3 receptor antagonists. Ondansetron is not a drug that stimulates gastric or intestinal peristalsis. It should not be used instead of nasogastric suction. The use of Ondansetron in patients following abdominal surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and/or gastric distension.
InteractionsView
Ondansetron does not itself appear to induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system of the liver. Because Ondansetron is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and hence, the half-life of Ondansetron. On the basis of available data, no dosage adjustment of Ondasetron is recommended for patients on these drugs.
Pregnancy & lactationView
Carcinogenic effects were not seen in 2-year studies in rats and mice with oral Ondansetron doses up to 10 and 30 mg/kg per day, respectively. Ondansetron was not mutagenic in standard tests for mutagenicity. Oral administration of Ondansetron up to 15 mg/kg per day did not affect fertility or general reproduction performance of male and female rats.
Reproduction studies have been performed in pregnant rats and rabbits at daily oral doses up to 15 and 30 mg/kg per day, respectively, and have revealed no evidence of impaired fertility or harm to the fetus due to Ondansetron. There are, however, no adequate and well-controlled studies in pregnant women. Ondansetron is excreted in the breast milk of rats. So caution should be exercised when Ondansetron is administered to a nursing women.

- Step 5: Wash your hands after taking Onsaf oral soluble film
Side effectsView
Frequently reported adverse events were headache, constipation and diarrhea, but the majority have been mild or moderate in nature. In chemotherapy-induced nausea and vomiting, rash has occurred in approximately 1% of patients receiving Ondansetron. There also have been reports to a sensation of flushing or warmth, hiccups and liver enzyme abnormalities. Rare cases of anaphylaxis, brochospasm, tachycardia, angina (chest pain), hypokalemia, shortness of breath have also been reported, except for bronchospasm and anaphylaxis, the relationship to Ondansetron is unclear. There have been no evidence to extrapyramidal reactions, in rare case oculogyric crisis appearing alone, as well as with other dystonic reactions without definitive clinical evidence. In case of PONV, with the exception of headache, rates of these events were not significantly different in the Ondansetron and placebo groups.
ContraindicationsView
Contraindicated in patients known to have hypersensitivity to the drug or any of its components. Concomitant use of apomorphine.
PrecautionsView
Hypersensitivity reactions have been reported in patients who have exhibited hypersensitivity to other selective 5-HT3 receptor antagonists. Ondansetron is not a drug that stimulates gastric or intestinal peristalsis. It should not be used instead of nasogastric suction. The use of Ondansetron in patients following abdominal surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and/or gastric distension.
InteractionsView
Ondansetron does not itself appear to induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system of the liver. Because Ondansetron is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and hence, the half-life of Ondansetron. On the basis of available data, no dosage adjustment of Ondasetron is recommended for patients on these drugs.
Pregnancy & lactationView
Carcinogenic effects were not seen in 2-year studies in rats and mice with oral Ondansetron doses up to 10 and 30 mg/kg per day, respectively. Ondansetron was not mutagenic in standard tests for mutagenicity. Oral administration of Ondansetron up to 15 mg/kg per day did not affect fertility or general reproduction performance of male and female rats.
Reproduction studies have been performed in pregnant rats and rabbits at daily oral doses up to 15 and 30 mg/kg per day, respectively, and have revealed no evidence of impaired fertility or harm to the fetus due to Ondansetron. There are, however, no adequate and well-controlled studies in pregnant women. Ondansetron is excreted in the breast milk of rats. So caution should be exercised when Ondansetron is administered to a nursing women.

Indications
Post-operative nausea and vomiting
Indication detailsView
Ondansetron is a serotonin subtype 3 (5-HT3) receptor antagonist indicated:
- Prevention of nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy.
- Prevention and treatment of post-operative nausea and vomiting.
- Prevention of radiotherapy-induced nausea and vomiting.
Therapeutic classView
Anti-emetic drugs
PharmacologyView
Ondansetron is a potent, highly selective 5HT3 receptor-antagonist. Its precise mode of action in the control of nausea and vomiting is not known. Chemotherapeutic agents and radiotherapy may cause release of 5HT in the small intestine initiating a vomiting reflex by activating vagal afferents via 5HT3 receptors. Ondansetron blocks the initiation of this reflex. Activation of vagal afferents may also cause a release of 5HT in the area postrema, located on the floor of the fourth ventricle, and this may also promote emesis through a central mechanism. Thus, the effect of ondansetron in the management of the nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy is probably due to antagonism of 5HT3 receptors on neurons located both in the peripheral and central nervous system. The mechanisms of action in post-operative nausea and vomiting are not known but there may be common pathways with cytotoxic induced nausea and vomiting.
