title: After two years, did Viagra live up to its expectations?
abstract: Sildenafil (Viagra) is the first on-demand oral medication approved for treatment of male erectile dysfunction (ED). Since the unprecedented release of sildenafil, the initial surge of 'Viagra craze' has subsided and there is a considerable decline in world-wide prescriptions. We did a long-term efficacy study of sildenafil in our community practice to assess the discontinuation rate and the etiologic factors causing discontinuation.
