Pharmacology

Palonosetron is a 5-HT3 antagonist with a high affinity for this receptor and little or no affinity for other receptors. Chemotherapeutic agents are thought to cause nausea and vomiting by releasing serotonin from enterochromaffin cells in the small intestine, which then activates 5-HT3 receptors on nerve terminals.

 

Administration & Dosage

Typical dosage: Adults should take 0.5 mg of the tablet once a day. Adult IV dosage: A single 0.075 mg IV dose should be given over 10 seconds.

Nausea and vomiting caused by chemotherapy: Adult tablet dosage: 0.5 mg, given 1 hour before the start of chemotherapy. Adult IV dosage: 30 minutes before, a single 0.25 mg IV dose should be administered over 30 seconds.
