The present invention relates to liquid formulations of Fosaprepitant intended for parenteral administration. Further the invention also describes process for preparing such formulations.
Description
- Fosaprepitant is a P/neurokinin-1 (NK1) receptor antagonist and is a prodrug of Aprepitant. The meglumine salt of Fosaprepitant, Fosaprepitant dimeglumine, is approved in the U.S as Emend® in the form of a lyophilized powder for intravenous infusion. Fosaprepitant dimeglumine is rapidly converted to Aprepitant in vivo.
