Fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, is primarily employed in the prevention of chemotherapy-induced nausea and vomiting (CINV). Its application involves blocking the action of substance P, a neurotransmitter involved in the vomiting reflex. Chemically, fosaprepitant is a prodrug of aprepitant, designed for intravenous administration to ensure a more sustained and controlled release. Buy high quality Fosaprepitant from Molsyns Research.
