Bioactivity

Maropitant is a selective and orally active neurokinin (NK1) receptor antagonist. Maropitant acts by blocking the binding of substance P within the emetic center and the chemoreceptor trigger zone (CRTZ). Maropitant is highly effective in preventing vomiting[1][2].

In Vivo

Treatment with 1 mg/kg Maropitant citrate, significantly reduces the size of ulcerative dermatitis (UD) lesions in mice. Intravenous Maropitant decreases MAC by 16%. In contrast, epidural administration of either saline or Maropitant does not change the MAC (2.17% and 1.92 %, respectively).
