Routes Intravenous

Palonosetron (INN, trade name Aloxi) is a 5-HT3 antagonist used in the prevention and treatment of chemotherapy-induced nausea and vomiting (CINV). It is the most effective of the 5-HT3 antagonists in controlling delayed CINV—nausea and vomiting that appear more than 24 hours after the first dose of a course of chemotherapy—and is the only drug of its class approved for this use by the U.S. Food and Drug Administration.[1] As of 2007, it is the most recent 5-HT3 antagonist to enter clinical use.

Palonosetron is administered intravenously, as a single dose, 30 minutes before chemotherapy.[1] An oral formulation is currently under regulatory review, after the FDA accepted for review the supplemental New Drug Application (sNDA) for palonosetron capsules.[2][3]
