Aprepitant (CAS NO.170729-80-3) is classified as an NK1 antagonist. Aprepitant(170729-80-3) also has been shown to inhibit both the acute and delayed emesis induced by cytotoxic chemotherapeutic.
Aprepitant (CAS NO.170729-80-3) should not be used concurrently with pimozide, terfenadine, astemizole, or cisapride. Dose-dependent inhibition of CYP3A4 by Aprepitant could result in elevated plasma concentrations of these drugs, potentially causing serious or life-threatening reactions.
