Fosnetupitant is a prodrug form of netupitant. Netupitant is a selective antagonist of human substance P/neurokinin 1 (NK-1) receptors. Upon intravenous administration, fosnetupitant is converted by phosphatases to its active form. It competitively binds to and blocks the activity of NK-1 receptors in the central nervous system, by inhibiting binding of substance P (SP) to NK-1 receptors. This prevents delayed emesis, which is associated with SP secretion. AKYNZEO® is a combination of palonosetron, a serotonin-3 receptor antagonist, and netupitant (capsules for oral use) or fosnetupitant (injections for intravenous use). AKYNZEO® for injection is indicated in combination with dexamethasone in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy.

Sample Use Guides

In Vivo Use Guide

One AKYNZEO (netupitant and palonosetron) capsule administered approximately 1 hour prior to the start of chemotherapy with dexamethasone 12 mg administered orally 30 minutes prior to chemotherapy on day 1 and 8 mg orally once daily on days 2 to 4 (for highly emetogenic chemotherapy, including cisplatin based chemotherapy) or on day 1 with not necessary administration of dexamethasone on days 2 to 4 (for anthracyclines and cyclophosphamide based chemotherapy and chemotherapy not considered highly emetogenic)

Route of Administration: Oral

In Vitro Use Guide

HEK-293 cells were incubated with 5 nM [3H]-netupitant for 40 min at room temperature.
