Firocoxib

Firocoxib is a selective inhibitor of COX-2 (IC50s = 0.13 and 7.5 μM for COX-2 and COX-1, respectively, in isolated cat blood). It inhibits LPS-induced production of prostaglandin E2 (PGE2; ) in isolated dog, horse, and cat whole blood ex vivo. Firocoxib decreases lameness, induces analgesia, and improves range of motion in dogs and horses with osteoarthritis when administered at doses of 5 and 0.1 mg/kg per day, respectively. Formulations containing firocoxib have been used in dogs and horses with osteoarthritis.
