Selectively blocks the serotonin 5-HT3-receptor neurons of the Central (vomiting center) and peripheral (gastrointestinal) nervous system, reguliruemoe gag reflex. Not violate the coordination of movements, does not cause sedation and reduce efficiency. Does not change the concentration of prolactin in plasma.

Method of application and dose:

The choice of dosage regimen is determined by the severity emetogenic actions carried out by anti-cancer therapies. For adults, the daily dose is 8-32 mg/day, we recommend the following modes. At a moderate intensity emetogenic action of chemotherapy or radiotherapy - 8 mg/bolus or slow/m, just before the beginning of therapy. When a significant expression emetogenic action of chemotherapy: administered in/jet slowly to 8 mg immediately before chemotherapy and then/jet - 8 mg every 2-4 h or in/to drip continuously at a rate of 1 mg/h for 24 hours, or drip directly before the start of chemotherapy at a dose of 16-32 mg diluted in 50-100 ml of appropriate infusion solution for 15 min. odansetron Efficiency can be increased by single I/V administration of corticosteroids (e.g. 20 mg of dexamethasone) before beginning of chemotherapy. To prevent delayed vomiting that occurs after 24 hours from the start of chemotherapy or radiotherapy - at both high and moderate severity emetogenic action of the therapy recommended taking the drug in pill form. For oral administration: adults, to prevent nausea and vomiting on the background of chemo or radiotherapy, ondansetron administered at 8 mg 1-2 h before the start of antitumor therapy followed the methods of another 8 mg orally after 12 h. To prevent late (24 h) or prolonged vomiting, should continue to receive 8 mg 2 times a day for 5 days after the end of the course of anticancer therapy. To enhance the effect the dose can be increased to 24 mg and appointed simultaneously with 12 mg of dexamethasone phosphate (in the form of sodium salt) for 1-2 hours before start of chemotherapy. Children over 2 years:/in a dose of 5 mg/sq m body surface immediately before chemotherapy, followed by ingestion at a dose of 4 mg over 12 h After completion of chemotherapy should continue to receive ondansetron in a dose of 4 mg 2 times a day for 5 days.

When liver disease substantially reduces the clearance of ondansetron, increases T1/2 from plasma and require dose reduction to 8 mg/day.

Special instructions:

Patients who previously had allergic reactions to other selective blockers of 5-HT3 receptors, have an increased risk of their development against the background of the ondansetron. Ondansetron may slow down the motility of the colon, in connection with his appointment of patients with symptoms of intestinal obstruction requires special monitoring. The infusion solution is prepared immediately before use. If necessary it can be stored for 24 hours at 2-8 deg.With under normal light. During the infusion of protection from light is not required, diluted injectable solution retains its stability for at least for 24 h under natural light or normal lighting. For preparing an infusion solution can be used: 0.9% NaCl solution, 5% dextrose, 10% solution, mannitol, ringer solution, 0.3% KCl solution and 0.9% NaCl solution, a solution of 0.3% KCl and 5% dextrose. Lingual tablets contain aspartame, this should be considered when assigning patients with phenylketonuria.
