Chemotherapy-Induced Nausea and Vomiting—Adult

Neurokinin 1 (NK1) receptor antagonists (RAs) are a class of drug used to treat nausea and vomiting associated with chemotherapy. Aprepitant, casopitant, and fosaprepitant are NK1 drugs. Some evidence has suggested that fosaprepitant may be more helpful in the prevention of delayed nausea and vomiting.
