Primary Outcome Measures:
  • Changes of the total International Prostate Symptom Score (IPSS) score from baseline to 12 weeks of treatment in patients with severe symptomatic BPH refractory to tamsulosin 0.2mg (Harnal® 0.2mg, 1T) [ Time Frame: 12 weeks of treatment ] [ Designated as safety issue: Yes ]
