The efficacy and safety of fentiazac and diclofenac sodium in peri-arthritis of the shoulder: a multi-centre, double-blind comparison.
In a double-blind parallel group comparison of efficacy and safety, 19 patients with peri-arthritis of the shoulder received 200 mg fentiazac twice daily and 19 received 50 mg diclofenac sodium twice daily, with both drugs given orally for 3 weeks. In both groups, observers' verbal rating scales of pain severity at rest and on movement showed decreases that were significant by week 1. Both groups also had significant improvement in abduction, external rotation, retroversion and anteversion. At week 1, the patients reported improvement, on a verbal rating scale, of global effectiveness, but there were no subsequent changes. There were no statistically significant differences between the treatments in any of these variables. Five (26%) fentiazac-treated patients and four (21%) diclofenac sodium-treated patients reported adverse effects, mostly gastro-intestinal. One case of rash in each group and one case of pruritus in a diclofenac sodium-treated patient were severe enough for the patients to be withdrawn from therapy. There were no clinically significant changes in laboratory values. It was concluded that fentiazac (400 mg/day) and diclofenac sodium (100 mg/day) were equally effective within 1 week in decreasing pain severity and improving shoulder mobility.
