General information

Class/mechanism: Substance P/neurokinin 1 (NK1) receptor antagonist. Fosaprepitant is a prodrug of Aprepitant (Emend). Aprepitant is able to cross the blood-brain barrier and blocks substance P activation of tachykinin family neurokinin 1 (NK1) receptors, which reduces the incidence of acute and delayed emesis.[1][2][3]
Route: IV
Extravasation: no information available

For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]
