    Journal: Aktuelle Urol; 2003 Mar; 34(2):102-8. PubMed ID: 14566693.
    Abstract:
    PURPOSE: The efficacy of propiverine in elderly patients suffering from urge incontinence or urge-stress incontinence was intended to be investigated. Especially in elderly patients a cardiac influence of propiverine is possible due to its dual mode of action. That is why besides the efficacy especially the cardiac safety was intended to be investigated. MATERIAL AND METHODS: Ninety-eight patients (21 male, 77 female; 67.7 +/- 6.3 years of age) suffering from urgency, urge incontinence or mixed urge-stress incontinence were included in the double-blind, multicentre, placebo-controlled, randomized study. After a two-week placebo run-in period, the patients received propiverine (15 mg t. i. d.) or placebo (t. i. d.) for four weeks. Before (U 1, U 2) and during the treatment period (U 3, U 4), standard ECG's and 24 h long-term ECG's were recorded. RESULTS: Propiverine caused a significant reduction in the micturition frequency (U 2 : 8.7 +/- 4.2, U 4 : 6.5 +/- 3.2 ml; p < 0.01) reflected in a significant increase in the average micturition volume (U 2 : 163.5 +/- 65.9, U 4 : 216.3 +/- 101.5 ml; p < 0.01) and a significant reduction in the episodes of incontinence (- 54 %; p < or = 0.05). These findings were confirmed by the overall assessment after four weeks in which approximately 90 % of patients under propiverine were either free from urge incontinence and urge symptoms or improved. The efficacy parameters demonstrated a better efficacy for urge incontinence than for mixed urge-stress incontinence. Resting and ambulatory electrocardiograms evidenced no significant changes. Neither QTc interval nor other cardiac parameters were relevantly altered. The frequency of cardiac events (Lown classes IV a/b) was fortuitous, revealing no difference between placebo and propiverine. The incidence of adverse events was very low (2 % dryness of the mouth under propiverine) and confirmed by the findings from the quality of life questionnaires. CONCLUSIONS: A favourable benefit-risk ratio in the treatment of elderly patients suffering from urgency, urge incontinence or combined urge-stress incontinence is therefore proven for propiverine. Cardiac arrhythmia were not induced.
