[Topical therapy in erectile dysfunction].
All forms of pharmacological therapy result in a relaxation of the corporeal smooth muscle. Intracorporeal injection of vasoactive drugs was introduced around 15 years ago and still is the most effective therapy in erectile dysfunction. Resulting in a consistent success rate of 70-80% this form of therapy will find numerous applications, even after the introduction of effective oral agents such as sildenafil. Prostaglandin E1 and--less frequently used--the combination of papaverine and phentolamine are the mainstay of intracorporeal injection therapy. Intraurethral prostaglandin (MUSE) has recently become available and is somewhat less effective than injection therapy. Externally applied drugs (nitroglycerin paste on the penile shaft and minoxidil solution on the glans penis) have not succeeded in the long run. Vacuum erection devices represent a form of physical topical therapy that is very versatile and also effective but rather infrequently applied.
