Vardenafil Restores Erectile Function to Normal Range in Men with Erectile Dysfunction

ABSTRACT Introduction The ability of oral phosphodiesterase type 5 (PDE5) inhibitor therapy to restore erectile function to normal is an important attribute to men with erectile dysfunction (ED). Aim To assess the ability of vardenafil to restore normal erectile function in men with general ED. Methods In two fixed‐dose, parallel‐group, double‐blind, placebo‐controlled, pivotal studies, patients received vardenafil (5, 10, or 20 mg) or placebo for 12/26 weeks. Main Outcome Measure In this retrospective analysis, the percentage of patients “returning to normal” erectile function at week 12 (as defined by scores ≥26 on erectile function domain of International Index of Erectile Function [IIEF‐EF]) was determined, with further stratification by baseline ED severity, etiology, age, and duration of ED. Results Vardenafil 5, 10, and 20 mg returned 32%, 43%, and 49% of patients, respectively, to normal erectile function after 12 weeks, compared with 10% of patients receiving placebo ( P Conclusion Vardenafil improves the IIEF‐EF domain score to the normal range in a substantial proportion of men with ED.
