Mechanism of action

Ondansetron is a 5-HT3 receptor antagonist that blocks serotonin signaling in the chemoreceptor trigger zone. Aprepitant is a neurokinin-1 (NK1) receptor antagonist that blocks substance P signaling in the central nervous system. Dexamethasone is a corticosteroid that provides additional antiemetic effects through multiple mechanisms. Together, these agents target complementary pathways to provide comprehensive CINV prevention.
