      Maropitant is a neurokinin (NK1) receptor antagonist. MedChem Express, HY-10053
      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) MAC by 16% (1.74 ? 0.17%). In contrast, epidural administration of either saline or Maropitant did not change (p > 0.05) the MAC (2.17 ? 0.34% and 1.92 ? 0.12%, respectively). MedChem Express HY-10053
