> Maropitant API — Overview
Maropitant (CAS: 147116-67-4, also known as maropitant citrate active moiety, CJ-11,972, and Cerenia active ingredient) is a selective neurokinin-1 (NK1) receptor antagonist used as a veterinary pharmaceutical API for antiemetic formulations in dogs and cats. It blocks substance P at NK1 receptors involved in the vomiting reflex. Suzhou Pharmaceutical Technology Co., Ltd. supplies ≥98% Maropitant API in bulk from Suzhou, China, with export to South America, Australia, New Zealand, Mexico, Canada, and worldwide markets. Export documentation: COA and MSDS standard for all orders.

> Applications
Maropitant is used in veterinary antiemetic development because NK1 receptor antagonism can reduce emesis triggered by central and peripheral pathways. It is commonly associated with oral and injectable veterinary formulations for dogs and cats, including use around acute vomiting, motion sickness, perioperative nausea, and other veterinary treatment contexts where local approvals and prescription rules permit.
Canine vomiting and motion sickness
In two randomized clinical trials for canine motion sickness, maropitant significantly reduced vomiting compared with placebo after oral dosing before travel (Journal of Veterinary Pharmacology and Therapeutics, 2008, doi:10.1111/j.1365-2885.2008.00990.x). In another randomized clinical trial for treatment of vomiting in dogs, injectable and oral maropitant reduced continued vomiting compared with placebo (Journal of Veterinary Pharmacology and Therapeutics, 2008, doi:10.1111/j.1365-2885.2008.00992.x). These references support Maropitant API relevance for veterinary antiemetic formulation and research programs.
Veterinary formulation and research use
Maropitant API buyers usually evaluate assay, related substances, chiral purity, residual solvents, particle size, and stability data before moving from sample quantities to pilot or commercial batches. The material is intended for qualified pharmaceutical, compounding, or research buyers. Finished-dose development, registration, sale, and clinical use remain subject to the buyer’s local veterinary medicine regulations.
