Primary Outcome Measures:
  • Change from baseline in International Index of Erectile Function (5-item Version) at 12 and 24 week [ Time Frame: Baseline, 12weeks, 24 weeks ]
    • IIEF-5 questionnaire is used to assess male erectile function
    • IIEF-5 (5-item Version of the International Index of Erectile Function)is obtained by combining the scores of the responses to 5 questions. Each question is scored from 0-5 (1 questions is scored from 1-5) for IIEF-5 range of 1-25 points; lower numerical scores from the IIEF-5 questionnaire represnt greater severitt of erectile dysfunction.


Secondary Outcome Measures:
  • Change from baseline in SEP Q2,Q3 and GEQ [ Time Frame: baseline, 12weeks, and 24 weeks ]
    • SEP Q2 (Sexual encounter profile Q2) and SEP Q3 (Sexual encounter profile Q3) are used to assess erectile function
    • The efficaty of medication is followed by GEQ (Global efficacy question).

  • Number of patients with adverse events during 24 weeks of the study [ Time Frame: Baseline through 24 weeks ]

Enrollment: 80
