[Comparative studies of the effect of mictonorm (propiverin hydrochloride) and Spasuret (flavoxate hydrochloride) on the bladder detrusor muscle].

46 patients suffering from urgency/urge incontinency were treated with Mictonorm and Spasuret in a crossing-over study. In consideration of the placebo effect in this disease both agents were tested versus a non-verum. The application period was 4 weeks and the dosage was 45 mg/d Mictonorm and 300 mg/d Spasuret, respectively. Both with Mictonorm and with Spasuret a significant reduction of micturition frequency and an increase of the compliance could be observed, whereas the placebo was ineffective. A markedly growth of the maximal bladder capacity (16.9%) was obtained only by Mictonorm. Both agents keep likewise to an improvement of the symptoms or urgency/urge incontinency. Side effects could observed in a small size without a breaking-off of the treatment.
