[Hemodynamics of erection: current pharmacological findings]

Over twenty drugs were injected into the corpora cavernosa. Pharmacologically these drugs come under seven therapeutic categories. Two types of pharmacodynamics explain the mode of action of these agents on the erectile tissues. The discovery of these drugs can be added to the array of investigations and actions normally used to study and remedy the problems of organic impotence, as well as a new test which may provide a therapeutic base for vascular rehabilitation and, in some cases, a substrate for a pharmacological prosthesis.
