Mechanism of action

Netupitant blocks neurokinin-1 (NK1) receptors, which are involved in the central processing of emetic signals, particularly for delayed nausea and vomiting. Palonosetron blocks serotonin 5-HT3 receptors on vagal afferents and in the chemoreceptor trigger zone, addressing acute nausea and vomiting. The dual mechanism provides comprehensive coverage across both acute and delayed phases of chemotherapy-induced nausea and vomiting (CINV).
