FDA Approves First Injectable Pentosan For Osteoarthritis In Horses

The Food and Drug Administration announced Dec. 20 that the agency has approved Zycosan, which contains pentosan polysulfate sodium for injection, to control clinical signs associated with osteoarthritis in horses. Zycosan is a heparinlike compound and is the first injectable pentosan product to receive FDA approval.

According to the FDA, Zycosan will be an important addition to the available approved drugs to control the clinical signs of osteoarthritis in horses. Unapproved injectable formulations of pentosan, including compounded formulations, have a long history of use in horses, but Zycosan is the first injectable pentosan product to have met FDA standards for safety, efficacy, and consistent manufacturing processes. The agency strongly encourages veterinarians to use legally marketed, FDA-approved Zycosan when pentosan is indicated for use in an equine patient.


Anzac Animal Health LLC, the sponsor of Zycosan, conducted a field study in client-owned horses that had lameness in one leg and were diagnosed with osteoarthritis in the lame leg. On day 28, more horses in the Zycosan-treated group had improved lameness grades, compared with a control group.
