NCIt definition : A selective neurokinin 1 (NK1) receptor antagonist with potential antiemetic activity.
Netupitant competitively binds to and blocks the activity of the human substance P/NK1
receptors in the central nervous system (CNS), thereby inhibiting NK1-receptor binding
of the endogenous tachykinin neuropeptide substance P (SP), which may result in the
prevention of chemotherapy-induced nausea and vomiting (CINV). SP is found in neurons
of vagal afferent fibers innervating the brain-stem nucleus tractus solitarii and
the area postrema, which contains the chemoreceptor trigger zone (CTZ), and may be
elevated in response to chemotherapy. The NK-receptor is a G-protein receptor coupled
to the inositol phosphate signal-transduction pathway and is found in both the nucleus
tractus solitarii and the area postrema.;
