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 > or =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 < 0.0001). Return to normal IIEF-EF domain scores was noted irrespective of severity, etiology, age, and duration of ED, and was observed even in challenging-to-treat subgroups. With vardenafil 20 mg, 39% of men with severe ED at baseline, 45-49% of men with ED of mixed or organic etiology, 35% of men aged > or =65 years, and 43% of men with ED of > or =3 years of duration returned to normal erectile function at week 12. Mean per-patient SEP3 (question 3 on the Sexual Encounter Profile) success rates in patients achieving IIEF-EF domain scores > or =26 ranged from 87% to 95%.

CONCLUSION: Vardenafil improves the IIEF-EF domain score to the normal range in a substantial proportion of men with ED.
