Chemotherapy-Induced Nausea and Vomiting—Adult
Description 

Neurokinin 1 (NK1) receptor antagonists are in a class of drug used to treat nausea and vomiting associated with chemotherapy. Aprepitant, casopitant, and fosaprepitant are NK1 drugs. There is some evidence that fosaprepitant may be more helpful in the prevention of delayed nausea and vomiting (dos Santos, Souza, Brunetto, Sasse, & Lima, 2012). NK1 antagonists are effective for both adult and pediatric patients. However, the use and most appropriate dosing among pediatric patients of various age groups has not been determined.
