Dechra Announces FDA Approval of Emeprev™ (maropitant citrate) Injectable Solution

New bioequivalent provides veterinarians with an in-clinic antiemetic option to support patient relief from vomiting and helping to ensure clinical confidence

OVERLAND PARK, Kan.--(BUSINESS WIRE)--Dechra, a global leader in veterinary specialty care, today shares the FDA approval of Emeprev™ (maropitant citrate) Injectable Solution, the first FDA-approved bioequivalent injectable solution to the most widely used antiemetic for dogs and cats.¹

Indicated for the prevention and treatment of acute vomiting in dogs and the treatment of vomiting in cats, Emeprev™ sets a new standard for patient and clinic experience:

• Differentiated Preservative for Comfort: Emeprev™ contains benzyl alcohol, a preservative demonstrated to act as a local anesthetic and reduce pain during injection in healthy laboratory dogs.² In a study of healthy laboratory dogs, subcutaneous injection of Emeprev™ was significantly less painful than the pioneer drug.²
• Simple Storage: Emeprev™ requires no refrigeration, streamlining clinic operations and making it easier for veterinary teams to deliver care without added logistical challenges.

Trusted Effectiveness, Now with a New Option

“Emeprev™ delivers the same trusted antiemetic effectiveness as the pioneer with a different preservative. It's a win for our patients and their caregivers,” said Dr. Christopher Byers, DVM, DACVECC, DACVIM (SAIM), CVJ, a Key Opinion Leader for Dechra.

A Leading Solution for Vomiting in Dogs and Cats

Maropitant is the most used medication for vomiting in dogs and cats¹, and Emeprev™ Injectable Solution is the first FDA-approved bioequivalent maropitant injectable solution, providing veterinarians with a reliable, in-clinic option to support patient relief from vomiting and helping to ensure clinical confidence.

“The introduction of Emeprev™ Injectable Solution builds on our continued commitment to providing veterinarians with high-quality, practical solutions they can trust,” said Laura Olsen, President, North America, and Chief Marketing Officer, Dechra. “We’re focused on expanding our companion-animal portfolio with products that address real-world clinical needs and strengthen the human–animal bond.”
