Maropitant (Synonyms: CJ-11,972)

Maropitant is a neurokinin (NK1) receptor antagonist. IC50 value:Target: NK1 receptorMaropitant is the first NK1 receptor antagonist developed to treat and prevent emesis in dogs. Treatment with 1 mg/kg Maropitant citrate, significantly reduced the size of ulcerative dermatitis (UD) lesions in mice. Intravenous Maropitant decreased (p 0.05) the MAC (2.17 ± 0.34% and 1.92 ± 0.12%, respectively).
