Fosaprepitant (Emend for Injection (US), Ivemend (EU)) is a prodrug of Aprepitant. Once biologically activated, the drug acts as a substance P/neurokinin 1 (NK1) receptor antagonist which, in combination with other antiemetic agents, is indicated for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy. Aprepitant is a selective high-affinity antagonist of human substance P/neurokinin 1 (NK1) receptors. Aprepitant has little or no affinity for serotonin (5-HT3), dopamine, and corticosteroid receptors, the targets of existing therapies for chemotherapy-induced nausea and vomiting (CI NV). Aprepitant has been shown in animal models to inhibit emesis induced by cytotoxic chemotherapeutic agents, such as cisplatin, via central actions. Animal and human Positron Emission Tomography (PET) studies with Aprepitant have shown that it crosses the blood brain barrier and occupies brain NK1 receptors. Animal and human studies show that Aprepitant augments the antiemetic activity of the 5-HT3-receptor antagonist ondansetron and the corticosteroid ethasone and inhibits both the acute and delayed phases of cisplatin induced emesis. In summary, the active form of fosaprepitant is as an NK1 antagonist which is because it blocks signals given off by NK1 receptors. This therefore decreases the likelihood of vomiting in patients experiencing. Fosaprepitant is used for the prevention of nausea and vomiting associated with highly emetogenic cancer chemotherapy.
