[Solifenacin in the treatment of patients with hyperactive urinary bladder]

Efficacy and tolerance of a novel antimuscarinic drug solifenacin succinate (vesicar) were studied in 55 patients with hyperactive urinary bladder (HUB). All the patients were divided into two groups: 27 patients of group 1 received solifenacin in a dose 5 mg/day, 28 patients of group 2--in a dose 10 mg/day. The 3-month treatment has improved symptoms of the HUB compared to the initial level: a daily number of vesical tenesmus reduced in patients of groups 1 and 2 by 47 and 51%, respectively; a number of episodes of urgent urine incontinence by 53 and 65%, voiding--by 24 and 26%, respectively. Most symptom incidence reduction (by 2/3) occurred within the first month of therapy. Tolerance to 5 and 10 mg/day solifenacine was satisfactory. The most frequent side effect was xerostomia (18.5 and 28.5%, respectively). The results of the study show that solifenacine in doses 5 and 10 mg/day is effective and safe drug for therapy of patients with hyperactive urinary bladder.
