1 The analgesic efficacy and tolerance of diflunisal in patients with osteoarthritis has been compared with ibuprofen and acetylsalicylic acid (ASA) in two clinical studies carried out double-blind for 12 weeks and then continued single-blind for a further 12 weeks. The studies involved 115 patients and 695 patients, respectively.
