Description
Inclusion Criteria:
- Clinical signs and symptoms of frequency and urgency related to benign prostatic hyperplasia for at least 3 months
- I-PSS(S) score of ≥ 12
- Maximum flow rate (Qmax) of 4 to15 mL/sec
- Mean urinary frequency of ≥ 8 micturitions per 24 hours and ≥ 1 episode of urgency per 24 hours as verified by the 3-day micturition diary
- Benign digital rectal examination (DRE) result
Exclusion Criteria:
- Clinically significant outflow obstruction
- Significant post void residue volume (PVR >100ml)
- Prostate specific antigen (PSA) ≥10 ng/mL
- Previous or planned prostate surgery, including transurethral resection of the prostate (TURP)
- Transurethral microwave treatment (TUMT), transurethral needle ablation (TUNA), laser, or other invasive or minimally invasive procedures within 12 months
- Patient with a neurological cause for abnormal detrusor activity
- Patients with urinary tract infection, chronic inflammation, bladder stones, bladder neck, sclerosis, urethral stricture, prostatic cancer, severe vesical diverticulum
- Uncontrolled narrow angle glaucoma, urinary or gastric retention or any other medical condition which in the opinion of the investigator makes the use of anticholinergics contra-indicated
- Patients with any other complication which may cause voiding dysfunction
- Patients with severe hepatic dysfunction, severe renal dysfunction, severe cardiovascular disorder, orthostatic hypotension, or senile dementia
- Patients receiving any medication therapy for LUTS/BPH 2 weeks prior to the study
- Use of drugs to treat incontinence currently
- Hypersensitivity to tamsulosin and/or solifenacin or to any component of the formulation
- Any clinically significant condition, which in the opinion of the investigator makes the patients unsuitable for the trial
- Patients had taken any investigational drug in the previous 3 months prior to this study
