Forty patients with definite or classical rheumatoid arthritis were entered for 3 months in a double-blind trial, 20 patients on 400 mg fentiazac or 200 mg sulindac daily. Statistically significant improvements on fentiazac were reported during the course of the study for 3 of 7 parameters: pain score, total joint score and number of swollen joints, while for sulindac a significant improvement was reported for 6 parameters: pain score, grip strength, joint size, total joint score, number of swollen joints and erythrocyte sedimentation rate. Side-effects were reported during the 3-month comparative period for 3 patients receiving fentiazac, consisting of rash, headache, epigastric pain, and for 1 patient receiving sulindac who suffered from gastro-intestinal intolerance. Because of ineffectiveness and/or side-effects, the treatment had to be discontinued for 5 patients in the fentiazac group and for 3 in the sulindac treatment group. The results support earlier evidence that fentiazac and sulindac have analgesic and anti-inflammatory properties controlling disease activity in rheumatoid arthritis, sulindac being the more effective. During a long-term tolerance study, 3 of 33 patients continued on fentiazac developed a reversible hepatotoxicity possibly due to the drug. 相似文献

A double-blind crossover trial was carried out in 24 patients to compare the effects of mefenamic acid, flurbiprofen, sulindac and placebo. Each drug was given for 2 weeks, the treatment sequence being randomized. Daily doses were 1500 mg mefenamic acid, 150 mg flurbiprofen or 150 mg sulindac. All of the active drugs were significantly superior to placebo in terms of pain score, patients' assessment, articular index of joint tenderness, and duration and severity of morning stiffness. There was improvement in grip strength compared with placebo, but the differences were not statistically significant with sulindac. There was slight reduction in joint circumference but this was only statistically significant in the right hand with flurbiprofen and sulindac. No significant differences were found in technetium uptake in knee joints. The three drugs appeared to be equally effective and tolerated, and no significant differences were noted. 相似文献
