Alpha-adrenoreceptor antagonists have become the primary medical treatment for lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). The next treatment method is trans-urethral resection of prostate (TURP). TURP is the most efficient BPH treatment for relieving symptoms and improving uroflow, but it is also the invasive and morbid.
Tamsulosin has higher selectivity for the pharmacological a1-adrenoceptor subtype and the cloned a1a subtype than for the a1b subtype. Tamsulosin 0.4 mg improved Qmax to a slightly greater extent than alfuzosin 10 mg.(26% and 16% versus baseline, respectively)(http://www. fda.gov/cder/approval/ index.htm;accessed October 27, 2003.) and Tamsulosin 0.4 mg o.d. has been reported to be well tolerated irrespective of age and/or cardiovascular comorbidity/co-medication (Michel et al 1998) and no interaction with several antihypertensive agents has been reported. (Lowe et al. 1997) Our study is to explore the efficacy and safety of tamsulosin 0.4mg (Harnal® D. 0.2mg, 2T) in patients with LUTS/BPH refractory to tamsulosin 0.2mg (Harnal® D 0.2mg, 1T).

- To explore the efficacy of tamsulosin 0.4mg (Harnal® D. 0.2mg, 2T)in reducing the score of International Prostate Symptom Score (IPSS) from baseline to 12 weeks of treatment in patients with LUTS/BPH refractory to tamsulosin 0.2mg (Harnal® 0.2mg, 1T) [ Time Frame: 12 weeks of treatment ]
- To evaluate efficacy on maximal flow rate and post-voided residual urine To evaluate efficacy on voiding frequency , nocturia To explore the tolerability and safety [ Time Frame: 4 weeks and 12 weeks of treatment ]
