ABSTRACT

Introduction.  Clinical trials show that vardenafil produces effective and satisfactory first-dose success rates and reliability for erection and intercourse in men with erectile dysfunction (ED).

Aim.  This study was conducted to evaluate real-life efficacy, safety, and acceptance of vardenafil in men with ED.

Methods.  This open-label, prospective study, conducted in 6,740 U.S. centers, included an initial visit and one or two follow-up visits within a 2-month period of the first vardenafil dose. Vardenafil was administered in 5–20 mg doses.

Main Outcome Measures.  Efficacy variables included first-dose success rates for vaginal penetration, maintenance of erection, and satisfaction based on physician and patient assessments. Safety was assessed by adverse events (AEs).

Results.  A total of 30,010 men were included in the safety/intent-to-treat (S/ITT) analysis, with 26,043 men in the adjusted S/ITT population. Vardenafil improved erectile function in 78% of men, with 75% rating overall efficacy as “satisfying” or “very satisfying.” The overall rates of successful penetration and maintenance with vardenafil following the first dose were 78% and 68%, respectively. For men with mild and moderate ED, first-dose success rates for penetration were 89% and 82%, respectively, and for maintenance, 82% and 71%, respectively. First-dose penetration and maintenance of erection rates were 76% and 66%, respectively, for men with self-reported hypertension, and 70% and 60%, respectively, for men with diabetes mellitus. At study end, 67% of patients preferred to continue using vardenafil. The most frequently reported AEs were headache (4%) and flushing (2%). Vardenafil was well tolerated, with a “satisfied/very satisfied” tolerability rating in 75% of cases as assessed by the physician.

Conclusions.  This observational study demonstrated the tolerability and efficacy of vardenafil in men with ED and comorbidities. Vardenafil provided a high rate of first-dose intercourse success and a favorable safety profile in patients with and without comorbid disease. Cheng E.
