N2 - Objectives. To determine the efficacy and safety of fixed-dose oral sildenafil in patients with erectile dysfunction (ED) of various etiologies. Methods. In a 12-week, double-blind, randomized, placebo-controlled, fixed- dose study, 514 men (mean age 56 years) with ED were randomized to receive 25, 50, or 100 mg of sildenafil or placebo. The primary etiology of ED was determined to be organic in 32% of men, psychogenic in 25%, or mixed in 43%. Sildenafil or placebo was taken in the home setting approximately 1 hour before sexual activity, not more than once daily. Efficacy was determined by responses to question 3 (ability to achieve an erection) and question 4 (ability to maintain an erection) of the 15-item International Index of Erectile Function (IIEF). Other measures of efficacy included the five sexual function domains of the IIEF, a global efficacy question, event log data, and a partner questionnaire. Results. Sildenafil significantly increased patients' ability to achieve and maintain erections (P
