Eligible subjects (total n = 146) randomly assigned receive tamsulosin 0.2 mg (Group I, 44), solifenacin 5 II , 55), 10 III 47) for 12 weeks. Efficacy safety assessments each group done using detailed questionnaires, evaluating parameters such as maximal flow rate Qmax postvoid residual volume PVR at 4 Results Groups (combined use solifenacin) showed significant improvement storage I (tamsulosin monotherapy), reflected by subscore P < 0.05). Dry mouth developed four (7%) eight (17%) cases respectively, so that one (2%) three (6%) dropped out respectively. Two (4%) AUR them was withdrawn from study.
