Aprepitant (EMEND): The role of substance P in nausea and vomiting

Abstract

Aprepitant (EMEND) is the first commercially available drug from a new class of agents, the Substance P/neurokinin NK-1 receptor antagonists. Aprepitant is indicated for prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV) associated with highly emetogenic chemotherapy in adults. Its ability to antagonize the effects of Substance P has lead to greater understanding of the pathophysiology of nausea and vomiting. Its broad range of activity against a wide variety of central and peripheral emetogenic stimuli make it potentially useful in non-chemotherapy related nausea and vomiting. © 2005 by The Haworth Press, Inc.
