Abstract
The results of an open exploratory trial with different regimens of indoprofen in patients with acute gouty arthritis are described. Two main daily regimens were assessed: (a) indoprofen 200 mg as an intravenous bolus, followed by slow infusion of 100 mg/hour for about 4 hours (24 attacks treated in twenty-three patients); and (b) indoprofen 400 mg as an intravenous bolus (13 attacks treated in twelve patients). In both regimens intravenous indoprofen was supplemented with 400–600 mg daily of indoprofen by mouth. The patient's response, as judged by pain, tenderness, local heat, redness, range of motion and joint circumference, was dramatic in both series, with no significant difference between them at any time of observation. Substantial improvement was apparent for subjective variables already within 2 hours after the beginning of treatment, and a complete resolution was obtained in 35 of 37 attacks within 48 hours. A mild adverse reaction was recorded in one patient for each group (dizziness and gastric pain, respectively). Intravenous indoprofen appears to afford an extremely rapid relief of acute gout; of the two regimens assessed, the second should be preferred in that it seems to be at least equally effective but less troublesome for the patients.
