In this month's Journal of Urology, there are several abstracts of studies and analyzes that will be presented at the AUA meeting in June. Here is one Pfizer-sponsored analysis confirming Viagra's efficacy and safety in patients with severe ED. BigKNY3 Journal of Urology #910 META-ANALYSIS OF THE EFFICACY OF SILDENAFIL (VIAGRA) IN THE TREATMENT OF SEVERE ERECTILE DYSFUNCTION. William D. Steers, Charlottesville, VA; and the Sildenafil Study Group (Presented by Dr. Steers). INTRODUCTION AND OBJECTIVES: Previous studies have indicated that sildenafil is an effective and well-tolerated oral treatment for erectile dysfunction (ED) associated with a broad range of etiologies. This meta-analysis was performed to assess the efficacy of sildenafil in a subgroup of men with severe ED. METHODS: for this meta-analysis, data for 3361 patients with ED (organic 60%, psychogenic 15%, mixed 25%) from 10 double-blind, placebo-controlled, fixed-dose studies of sildenafil (50-100mg) were merged. Sildenafil or placebo was taken as needed 1 hour prior to sexual activity for 8 weeks. The frequency of penetration (Q3) and the frequency of maintained erections (Q4) were assessed at week 0 (baseline) and week 8 using the 15-item, self-administered International Index of Erectile Function (IIEF). Responses were graded from 0 (did not attempt intercourse) or 1 (almost never/never) to 5 (almost always/always). Responders in this analysis were defined as patients reaching a final (end-of-treatment) score of > 1 from baseline CONCLUSIONS: The results of this meta-analysis indicate that sildenafil, at doses of 50 and 100 mg, is effective in men with severe ED, with response rates ranging from 46% to 73%.
