Maropitant (trade name Cerenia in the U.S. and other countries), used as maropitant citrate is a neurokinin (NK1) receptor antagonist, which was developed by Zoetis specifically for the treatment of motion sickness and vomiting in dogs. It was approved by the FDA in 2007 for use in dogs, and was later approved for use in cats. Maropitant also has anti-nociceptive (analgesic) properties. Maropitant inhibits binding of substance P to NK-1 receptors. Substance P is an emetogen experimentally, and is found endogenously, along with NK-1 receptors, in the emetic center, chemoreceptor trigger zone, and in vagal afferent nerves in the gastrointestinal tract.

Sample Use Guides

In Vivo Use Guide

For Prevention of Vomiting Due to Motion Sickness Administer Cerenia (Maropitant) Tablets orally at a minimum dose of 8 mg/kg (3.6 mg/lb) body weight once daily for up to 2 consecutive days. Dogs should be fasted 1 hour prior to administration of Cerenia Tablets. Administer Cerenia Tablets 2 hours prior to travel.

Route of Administration: Oral

In Vitro Use Guide

Maropitant (0.1-10 uM) increased frequency of whole murine intestine contraction, decreased amplitude of contraction and totally inhibited motility index in a concentration-dependent manner.
