[Combination therapy with anticholinergics and alpha-blockers for the treatment of overactive bladder in female patients--pilot study].


PMID 21246788

Abstract

Overactive bladder (OAB) is one of the most common medical conditions with an estimated 16 percent of adult population being affected in Europe. The administration of anticholinergics is considered as the most frequent and most effective treatment. There is a evidence that alpha-blockers affect a detrusor function. The aim of the study is to investigate if the combinant therapy consisting of anticholinergics plus alpha-blockers could be beneficial for women suffering from OAB. 28 female patients with OAB were included into the pilot study. Mean age of the patients was 54.8 (42-77) years. Patients have been randomised into two groups: one group of patients has been treated by propiverin 30 mg daily, another group of patients has been treated by combination of both propiverin 30 mg daily and tamsulosin 0.4 mg daily. Satisfaction with the treatment has been evaluated by I-QoL questionnaire. Semi-objective parameters have been obtained by analysis of 3-days voiding diaries (number of micturitions, number of urgency episodes, voided volume). Peak flow (Qmax) has been measured as a objective parameter. We observed a decrease of frequency by 2.833 (-23.43%) comparing to base-line, decrease of number of urgency episodes by 1.417 (-36.22%), increase of voided volume by 33.333 ml (+19.14%), increase of quality of life index by 22.583 (+51.52%) and increase of Qmax by 0.17 ml/s (+0.58%) in the propiverin group. We observed decrease of frequency by 3.813 (-30.48%), decrease of number of urgency episodes by 1.875 (-45.52%), increase of voided volume by 51.250 ml (+26.88%), increase of quality of life index by 33.438 (+76.0%) and increase of Qmax by 2.13 ml/s (+7.87%) in the combination treatment group. No significant difference has been found between both groups except the quality of life index. Our results can not show explicitly higher efficacy of combination treatment using anticholinergics plus alpha-blockers comparing to standard therapy by anticholinergics alone. Further randomised placebo-controlled studies are needed for final evaluation of the role of alpha-blockers in the treatment of OAB.
