Double-blind trial comparing bufexamac infiltrations with triamcinolone acetonide infiltrations in patients with periarthritis of the shoulder

Abstract

A double-blind trial was carried out in 40 patients with an acute episode of periarthritis of the shoulder to compare the effectiveness and toleration of local infiltrations of bufexamac and triamcinolone acetonide. Patients received 1 or 2 local infiltrations with either 20 mg bufexamac or 40 mg triamcinolone acetonide. The results were evaluated by objective and subjective assessments of pain, loss of function, mobility, and by doctors' and patients' opinions of relief. There was a significant, comparable reduction in pain and discomfort in both groups after the first injection. Fourteen patients in each group required a second injection, with slightly more improvement in those receiving bufexamac. Local intolerance of the injections was noted in approximately 25% to 30% of the patients.
