Nabumetone, a new non-steroidal anti-inflammatory drug: a comparison with naproxen

Nabumetone, 500 mg two nocte, was compared with naproxen, 250 mg two nocte and one mane, in the management of 24 patients with rheumatoid arthritis attending an outpatients clinic. Both drugs were generally well tolerated and were of comparable efficacy in the dose employed. Similar numbers incurred side effects while taking either drug, but severe side effects, requiring withdrawal from the trial in two cases, were restricted to those patients taking naproxen. As patients known to be intolerant to naproxen were excluded from the trial, the results could have been expected to favour naproxen in this respect. Nabumetone may have a useful role in the management of patients with poor tolerance of other anti-inflammatory drugs.
