Methods We investigated the efficacy and safety of alprostadil formulated for intracavernosal treatment in three separate multi-institutional, prospective studies in men with erectile dysfunction of vasculogenic, neurogenic, psychogenic, and mixed causes. Clinical and laboratory evaluations of erection and the feasibility and satisfactoriness of sexual activity as assessed both by the men and by their partners were the primary measures of efficacy.

In a dose-finding study of 201 men, the minimal effective dose was <2 μg in 23, 20, 38, and 23 percent of men with ...
