描述 | Fenbufen is a non-selective non-steroidal anti-inflammatory drug (NSAID), used to treat acute and chronic painful conditions. Fenbufen at both doses (800 mg or 400 mg, oral) had apparent analgesic efficacy[3]. Fenbufen is a phenylalkanoic acid derivative with analgesic and anti-inflammatory activity. At a daily dosage of 600 mg, fenbufen is comparable with aspirin 3.6 g or indomethacin 75 mg in osteoarthritis[4]. Like clinically used nonsteroidal anti-inflammatory drugs, Fenbufen shows activity in a wide spectrum of laboratory tests in mice, rats, guinea pigs, and dogs. Fenbufen has a long duration of anti-inflammatory and analgesic activity. Mechanistic studies indicate that fenbufen has no intrinsic effect on cyclooxygenase activity, whereas its major metabolite, biphenylacetic acid, is a potent inhibitor of prostaglandin synthesis. Comparative studies in the type II collagen arthritis model indicate that the anti-inflammatory properties of fenbufen are more potent than those of a second nonsteroidal anti-inflammatory drug, sulindac[5]. |
