Azasetron is an antiemetic drug. It acts as serotonin 3 receptor antagonist. It is currently used to prevent nausea and vomiting caused by cancer chemotherapy (including cisplatin chemotherapy). Also it was demonstrated that azasetron has potent antimitogenic and apoptotic effect on cancer cell line. It was preclinically tested to treat cocaine abuse.

Intravenous: The recommended adult dosage is 10 mg, administered once daily. If the efficacy is not sufficient, the same dose may be additionally administered. The total daily dosage should not exceed 20 mg.Oral: The recommended adult dosage is 10 mg, administered once daily. The dose may be appropriately adjusted, according to patient age and symptoms. The total daily dosage should not exceed 15 mg.

In Vitro Use Guide

The effect of 5-HT3 receptor agonists and antagonists on the hypoxia/hypoglycemia (ischemia)-induced decrease in CA1 field potential elicited by stimulation of Schaffer collaterals was investigated using rat hippocampal slices. Treatment with the 5-HT3 receptor antagonist Y-25130 (0.1-100 uM) produced dose-dependent neuroprotection against the ischemia-induced decrease. However, in normal non-ischemic solution these treatments did not significantly change the CA1 field potential. The magnitude of protection in the Y-25130-treated group (EC50, 1.8 uM) was about 20 times greater than that in the ketanserin-treated group (EC50, 33 uM).
