Biochem/physiol Actions

Fosaprepitant dimeglumine acts as a therapeutic agent to treat chemotherapy-induced nausea and vomiting. It also acts as a weak inhibitor of cytochrome P450 3A4 (CYP3A4).
Fosaprepitant dimeglumine is a Substance P/neurokinin-1 (NK1) receptor antagonist. It is a water soluble prodrug of the antiemetic drug aprepitant.

Aprepitant and fosaprepitant, commonly used for the prevention of chemotherapy-induced nausea and vomiting, alter cytochrome P450 activity. This systematic review evaluates clinically significant pharmacokinetic drug interactions with aprepitant and fosaprepitant and describes adverse events ascribed to drug interactions with aprepitant
Bernardo L Rapoport et al.
Future oncology (London, England), 14(1), 77-92 (2017-11-14)
Chemotherapy-induced nausea and vomiting (CINV) remains a challenge in cancer care. Improved understanding of CINV pathophysiology has triggered the development of new antiemetic therapeutic options, such as selective neurokinin-1 (NK1) receptor antagonists (RAs), which effectively prevent CINV when added to
