The Efficacy of Solifenacin With or Without Tamsulosin in Adult Women With Overactive Bladder (OAB)
- Conditions
- Overactive Bladder
- Interventions
- Registration Number
- NCT01533597
- Lead Sponsor
- Soonchunhyang University Hospital
- Brief Summary
The aim of the study is to investigate if the combination therapy consisting of anticholinergics plus alpha-blockers could be beneficial for women suffering from Overactive Bladder (OAB).
- Detailed Description
Overactive bladder (OAB) describes the symptom complex of urgency, with or without urge incontinence, usually with frequency and nocturia.
The lower urinary tract is innervated by both the parasympathetic and the sympathetic nervous system, that act via muscarinic and adrenergic receptors, respectively.
Antimuscarinics are mainly used for the treatment of patients with OAB, especially women. Other than antimuscarinics, a1-blockers have been shown in several clinical reports to be useful in treating DO caused by neurological diseases.

Group Intervention Description Solifenacin Solifenacin - Solifenacin plus Tamsulosin Solifenacin plus Tamsulosin -
- Primary Outcome Measures
Name Time Method Change in Mean Number of Micturition Episodes Per 24 Hours at week 24 relative to baseline
- Secondary Outcome Measures
Name Time Method Change of Qmax at week 24 relative to baseline maximal urinary flow rate (Qmax) assessed by uroflowmetry
Change of PVR at week 24 relative to baseline Change from baseline in Post-Void Residual (PVR) volume
Numeric Change of Urgency Episodes Per 24 Hours at week 24 relative to baseline Change in Total Score of OABSS at week 24 relative to baseline Total Score of OABSS(Overactive Bladder Symptom Score) is the sum of 4 questions, ranging from 0 (best possible outcome) to 15 (worst possible outcome)
Change in Score of IPSS at week 24 relative to baseline Total Score of IPSS(International Prostate Symptom Score) is the sum of 7 questions, ranging from 0 (best possible outcome) to 35 (worst possible outcome). The 7 symptom questions include feeling of incomplete bladder emptying, frequency, intermittency, urgency, weak stream, straining and nocturia, each referring to during the last month, and each involving assignment of a score from 0 to 5 for a total of maximum 35 points.
