We assessed the safety, efficacy and patient acceptability of vardenafil (Levitra, Bayer HealthCare, Leverkusen, Germany) under real-life conditions in patients with erectile dysfunction (ED) in a multinational post-marketing surveillance study. An initial and up to two follow-up visits were documented for 29 358 German ED patients receiving vardenafil. Patients were interviewed about overall treatment success, and individual sexual attempts were evaluated in a patient questionnaire. Overall erectile improvement was reported by 93.9% of physicians, and similar improvement rates were reported for both 10 mg and 20 mg vardenafil dosages. Most patients experienced improved erections after the first (73.6%) or second (88.5%) tablet. Sexual attempts were successful with respect to partner penetration in 94.9% of patients and with respect to maintenance of erection during intercourse in 87.7% of patients. Adverse drug reactions were very rare (1.3% of patients). Vardenafil was highly effective, reliable and well tolerated in ED patients treated under real-life conditions.
