Diflunisal in the treatment of osteoarthrosis: a double-blind study comparing diflunisal with ibuprofen.

A double-blind trial was carried out in 37 patients with osteoarthrosis to compare the efficacy and tolerance of 250 mg diflunisal twice daily with that of 400 mg ibuprofen 3-times daily over an 8-week period. Rating scale assessments were made, at the end of a preceding 1-week, wash-out period on placebo and at regular fixed intervals, of weight-bearing pain, night pain, a specific functional activity, and of the duration of inactivity stiffness. Patients' and physician's overall evaluations of response, taking side-effects into account, were made on completion of the study. The data collected indicated that in 30 patients completing the trial both treatments produced similar overall results and, with the exception of weight-bearing pain which appeared to be improved more in the ibuprofen group, diflunisal provided equal therapeutic benefit with fewer side-effects.
