Dechra Zycosan is a sterile, pale yellow to brownish yellow solution indicated for the control of clinical signs associated with osteoarthritis in horses. This intramuscular injectable treatment is administered once weekly over a 28‑day period to support improved mobility and comfort.
The effectiveness of Zycosan was demonstrated to the FDA in a well‑controlled field study. Horses showing at least a one‑grade improvement over baseline in the index limb on the AAEP lameness scale were considered treatment successes.
