Efficacy and safety of sildenafil citrate in men with erectile dysfunction and stable coronary artery disease.

This was a double-blind, placebo-controlled, flexible-dose study of the efficacy and safety of sildenafil in men with erectile dysfunction (ED) and clinically stable coronary artery disease (CAD). Patients were randomized to receive sildenafil or placebo for 12 weeks. Primary outcomes were questions 3 and 4 of the International Index of Erectile Function (IIEF). Secondary outcomes included the other IIEF questions and functional domains, the Life Satisfaction Checklist, the Erectile Dysfunction Inventory of Treatment Satisfaction, 2 global efficacy assessment questions, and intercourse success rate. By week 12, sildenafil-treated patients (n = 70) showed significant improvements on questions 3 and 4 compared with placebo-treated patients (n = 72; p <0.01). Larger percentages of sildenafil-treated patients reported improved erections (64%) and improved intercourse (65%) compared with placebo-treated patients (21% and 19%, respectively). Sildenafil-treated patients were highly satisfied with treatment and their sexual life compared with placebo-treated patients. Forty-seven percent of sildenafil- and 32% of placebo-treated patients experienced adverse events, including transient headache, hypertension, flushing, and dyspepsia. There were no serious drug-related cardiovascular effects. Thus, sildenafil is an effective and well-tolerated treatment for ED in men with CAD. Sildenafil was not associated with additional safety risks in this patient population.

Treatment responsiveness of the Self-Esteem And Relationship questionnaire in erectile dysfunction.

OBJECTIVES: To determine the treatment responsiveness of the disease-specific Self-Esteem And Relationship (SEAR) questionnaire in erectile dysfunction. METHODS: The SEAR questionnaire was administered at baseline and at the end of the study in 93 patients with erectile dysfunction enrolled in a 10-week, open-label, flexible-dose (50-mg sildenafil, adjustable to 25 mg or 100 mg) trial. Changes from the baseline score were analyzed using the paired t test. The correlation between the changes from baseline on the SEAR questionnaire and the Erectile Function domain of the International Index of Erectile Function was examined. RESULTS: Significant and meaningful differences (P = 0.0001) from baseline were observed in the two primary domains (Sexual Relationship and Confidence) and the two Confidence domain subscales (Self-Esteem and Overall Relationship). The magnitude of the change was quite high for most aspects (Sexual Relationship, effect size [ES] = 1.6; Confidence, ES = 1.0; Self-Esteem, ES = 1.1) and moderate for one (Overall Relationship, ES = 0.6). Changes in Erectile Function domain score correlated moderately with changes in the SEAR domain and subscale scores (Sexual Relationship, r = 0.69; Confidence, r = 0.48; Self-Esteem, r = 0.47; and Overall Relationship, r = 0.35; P
