Orodispersible tablet (ODT) formulations offer improved convenience over film-coated formulations and are preferred by many patients.


To investigate the efficacy and safety of an ODT formulation of 10 mg vardenafil administered on demand vs. placebo in a general population of men with erectile dysfunction (ED).


This was a 16-week, double-blind, multicenter, randomized, parallel-group, placebo-controlled study conducted at 40 centers across Europe and South Africa. Eligible participants were men aged > or = 18 years with ED for at least 6 months, in a stable heterosexual relationship for at least 6 months, highly motivated to obtain ED treatment, and making at least four attempts at sexual intercourse on four separate days, of which at least half were unsuccessful. Subjects were randomized to receive 12 weeks of treatment with either 10 mg vardenafil ODT on demand or placebo, and each treatment group was stratified such that approximately half of the subjects were aged > or = 65 years.


Primary measures were the erectile function domain of the International Index of Erectile Function (IIEF-EF) and the Sexual Encounter Profile questions 2 and 3 (SEP2, SEP3). Secondary measures included SEP diary questions 1, 4, 5, and 6; the Treatment Satisfaction Scale; and the Global Assessment Question.


Of the 409 men enrolled (54.8% aged > or = 65 years), 355 were included in the intent-to-treat population (vardenafil ODT, N = 183; placebo, N = 172). Vardenafil ODT therapy was statistically significantly superior to placebo for all primary (IIEF-EF, SEP2, SEP3) and secondary efficacy measures (all P < 0.0001). The incidence and type of treatment-related adverse events with vardenafil 10 mg ODT were comparable with those of the film-coated tablet formulation.


Treatment with 10 mg vardenafil ODT, taken on demand, significantly improved erectile function and was well tolerated in a broad population of men with ED.
