Fenbufen, a new non-steroidal anti-inflammatory agent in rheumatoid arthritis, its efficacy and toxicity

Abstract

Fenbufen, a new butanoic acid derivative with anti-inflammatory properties, was evaluated in an open-label study. It was found that fenbufen was an effective anti-inflammatory agent with tolerable and acceptable potential side-effects. Its advantages appeared to be its long clinical half-life and relatively mild toxicity and/or allergic response.
