Robenacoxib Injection is indicated for postoperative pain and inflammation associated with soft tissue surgery in dogs
Cronus Pharma has launched Robenacoxib Injection in the United States, giving veterinarians a new cost-effective option for managing postoperative pain and inflammation in dogs and cats.
The company said the product is the only FDA-approved bioequivalent to ONSIOR (robenacoxib) Injection, marking the first generic version of the injectable veterinary NSAID to reach the U.S. market.
Robenacoxib Injection is indicated for postoperative pain and inflammation associated with soft tissue surgery in dogs at least 4 months old. In cats at least 4 months old, it is indicated for pain and inflammation associated with orthopedic surgery, ovariohysterectomy and castration. In all cases, use is limited to a maximum of three days.
The 20 mg/mL solution is supplied in a 20 mL multidose vial and is now available through national and regional veterinary distributors across the United States.
"Addressing post-operative pain is imperative in both dogs and cats," said Scott A. Krick DVM – Consulting Technical Services Veterinarian at Cronus Pharma. "The launch of Robenacoxib Injection from Cronus Pharma provides a cost-effective NSAID option and reflects our commitment to expanding access to FDA-approved bioequivalent medications that support veterinarians, their patients, and pet owners."
The launch adds another FDA-approved veterinary product to Cronus Pharma’s growing portfolio as the company expands its presence in the animal health market.
"The launch of Robenacoxib Injection marks an important addition to Cronus Pharma's growing portfolio of FDA-approved veterinary products," said Janel Fisher, Vice President of Sales at Cronus Pharma.
"Innovation is at the heart of what we do, and we are continually looking for opportunities to bring meaningful new products to the veterinary market. This launch demonstrates our ability to turn that commitment to innovation into solutions that provide greater choice and value for the veterinary community."
The product was approved by the FDA under ANADA # 200-804 as bioequivalent to the reference listed new animal drug, ONSIOR (robenacoxib) Injection.
Federal law restricts Robenacoxib Injection to use by or on the order of a licensed veterinarian. The drug should not be used for more than three days or in animals younger than four months. Cronus Pharma also notes that serious adverse events, including hepatopathy, have been reported with long-term use of robenacoxib tablets in dogs.
