Oxaceprol, at 6 mg/kg/day for 7 days, significantly reduces both the surface area and wet weight of cotton pellet granulomas, being slightly less effective than indomethacin, 3 mg/kg.
Oxaceprol (6–54 mg/kg/day) given therapeutically had no effect on the primary paw oedema response, but inhibits secondary lesions in the ears and tail.
Oxaceprol does not inhibit the synthesis of prostaglandins in vitro, but markedly inhibits neutrophil infiltration into the joints of rats with adjuvant arthritis.
