Notes: Phenylbutazone-d9 is intended for use as an internal standard for the quantification of phenylbutazone (Item No. 70400) by GC- or LC-MS. Phenylbutazone is a non-steroidal anti-inflammatory drug and an inhibitor of the peroxidase activity of COX (IC50 = ~100 µM in the presence of hydrogen peroxide).{807} It also inhibits prostaglandin I synthase (IC50 = ~25 µM in the presence of hydrogen peroxide). Phenylbutazone (2 mg/kg) reduces increases in type II collagen levels in the inflamed joints of an equine model of LPS-induced acute synovitis.{60463} Formulations containing phenylbutazone have been used in the treatment of lameness in horses.
