Intra-articular treatment of inflammatory arthritis: double-blind trial comparing bufexamac with methylprednisolone...

A double-blind trial was carried out to weigh the effectiveness and tolerance of intraarticular injections of bufexamac (20 mg) against methylprednisolone (40 mg) in 40 patients with an acute bout of inflammatory arthritis. Leucocyte and polymorphonuclear counts and viscosity measurement of the synovial fluid were performed before and 14 days after injection, which showed methylprednisolone to be significantly superior to bufexamac in suppressing inflammation. In both groups a statistically significant improvement of pain on mobilisation and pain index was noted, but the number of clinical remissions was significantly higher in the methylprednisolone group. The blind investigator found a statistically significantly greater improvement with methylprednisolone than with bufexamac, and patients' opinion on effectiveness did not differ significantly. Important local or general side-effects were not observed. It was concluded that, although both drugs appeared to exert a considerable anti-inflammatory effect in inflammatory arthritis, methylprednisolone was more effective.
