Osetron
Description
Osetron®is a selective 5-HT3serotonin receptor antagonist. 5-HT3serotonin receptors are present both peripherally on vagal nerve terminals and centrally in chemoreceptor trigger zone. During chemotherapy and postoperative period; excessive serotonin secrets from the enterochromaffin cells of the small intestine. The released serotonin stimulates the 5-HT3serotonin receptors of the vagal nerve terminals and chemoreceptor trigger zone which initiate vomiting reflex. Ondansetron is indicated for the prevention of chemotherapy & radiotherapy induced nausea and vomiting. It also prevents the postoperative nausea and vomiting.

Indications
Osetron®(tablets, syrup, and injection) is indicated for the prevention and treatment of nausea and vomiting induced by cytotoxic therapy and radiotherapy, postoperative nausea & vomiting.

Osetron®(injection) is indicated for nausea & vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including high dose cilastin. Osetron®injection also indicated for the prevention and treatment of post-operative nausea and vomiting.

To protect against delayed emesis after initial treatment one Osetron®8 mg tablet or 10 ml (2 teaspoonfuls equivalent to 8 mg of Ondansetron) of Osetron®oral solution should be administered twice a day (every 12 hours) for up to 5 days . For prevention and treatment of post-operative nausea and vomiting (injection only): Osetron®4 mg injection should be administered as a single dose, given by intramuscular or slow intravenous injection. If necessary, the dose may be increased up to 8 mg.

Contraindications
Ondansetron is contraindicated for patients known to have hypersensitivity to the Ondansetron or to any of its ingredient.

Precautions
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 distention.

Side effects
Generally Ondansetron is well tolerated. However few side effects including headache, diarrhoea, fatigue, dizziness and constipation may be seen after Ondansetron is administered.

Pregnancy & lactation
There are no adequate and wellcontrolled studies in pregnant women. This drug should be used during pregnancy is therefore not recommended expect for compelling reasons. Ondansetron is excreted in the breast milk of rats. It is not known whether Ondansetron is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Ondansetron is administered to a nursing woman.

Drug interactions
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 limited available data, no dosage adjustment is recommended for patients on these drugs.

Overdose
There is no specific antidote for Ondansetron overdose.If overdose is occurred, symptomatic and supportive therapy should be given as appropriate.
