Intracavernous Alprostadil Alfadex—an effective and well tolerated treatment for erectile dysfunction. Results of a long-term European study

Abstract

Long-term efficacy and safety of Alprostadil-Alfadex (EDEX^R/VIRIDAL^R) in intracavernous self-injection therapy for chronical erectile failure was investigated in a four year running multicenter European trial. Of the 16 886 protocolled injections 93% (15 713) resulted in rigid erections followed by successful sexual intercourse. Reported side effects by patients were prolonged erections >6 h only occurring during the first year in 1.2% (2 out of 162), painful erections in 29% (47 out of 162) during the first year and decreasing to 12.1% by year 4, hematomas, neither requiring therapeutic measures nor impeding sexual performance in 33.3% (54 out of 162) in year 1 with a decrease to 12.1% by year 4, fibrotic penile alterations such as nodules, plaques or deviations in 11.7% (19 out of 162) with spontaneous healing in 48% (9 out of 19). Of the 162 patients involved in this trial 54 completed the 4 y. Of the 54 completers 91.4% considered the tolerability good or very good and were satisfied or very satisfied with self-injection therapy with Alprostadil-Alfadex. The respective rates of the female partners were 51.7% very satisfied and 39.7% satisfied.

These data of the world-wide longest running prospective trial with a vasoactive drug in self-injection therapy provided impressive proof that Alprostadil-Alfadex represents a very effective and safe treatment for erectile dysfunction of both psychogenic and organogenic origin.
