Drug Mode of Action ::  

Ondansetron antagonises selective 5-HT3-receptor, blocking serotonin, both peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone. This action of ondansetron gives it its antiemetic property to prevent emesis due to acute chemotherapy mediated by serotonin.

Drug Interactions ::

May reduce analgesic effect of tramadol. Rifampicin and other CYP3A4 inducers may reduce levels/effects of ondansetron. Concomitant use of QT-prolonging agents (e.g. antiarrhythmics) may cause additive prolongation of QT interval. May increase the risk of arrhythmias w/ cardiotoxic drugs (e.g. anthracyclines). Potentially Fatal: May increase the hypotensive effect of apomorphine.
