Mechanism of action

Fosnetupitant blocks neurokinin-1 (NK1) receptors, which are involved in the delayed phase of CINV, while palonosetron blocks serotonin 5-HT3 receptors, which mediate the acute phase of CINV. This dual-mechanism combination provides enhanced antiemetic coverage across both acute and delayed phases of chemotherapy-induced nausea and vomiting.
