An analysis of piroxicam in rodent models of arthritis

Piroxicam, a potent, long acting non-steroidal anti-inflammatory drug, was tested in several rodent models of arthritis to assess further the possible mechanisms underlying its anti-inflammatory action. Piroxicam inhibited rat adjuvant disease and its associated manifestations, which include erosion of bone and cartilage (as evidenced by X-ray examination), soft tissue swelling and disease-induced weight loss. Piroxicam also inhibited the edema, the total leukocyte infiltration and the mononuclear cell infiltration into the carrageenan-injected pleural cavity of the rat. The possible relationship of these effects to the clinical activity of piroxicam is discussed.
