Aim: To evaluate the efficacy and tolerability of vardenafil, a phosphodiesterase type-5 (PDE-5) inhibitor, in men of Asian ethnicity with erectile dysfunction (ED).

Methods: In this prospective, double-blind, multinational study, Asian men were randomized to receive vardenafil (10 mg) or placebo (4:1 ratio) for 12 weeks. The primary efficacy variables were the International Index of Erectile Function erectile function domain (IIEF-EF), and Sexual Encounter Profile (SEP) questions related to penetration and intercourse completion.
