Oral pharmacotherapy and the contemporary evaluation and management of erectile dysfunction.
The introduction of phosphodiesterase-5 (PDE-5) inhibitor therapy for the treatment of erectile dysfunction (ED) marked the beginning of a much greater awareness of this condition and its effects on quality of life. Resulting research has provided much data on the etiologies of ED, the risk factors involved, and the connection between ED and atherosclerotic disease. With the ED patient more frequently seeking treatment from his primary care physician, it behooves both urologists and non-urologist physicians to be familiar with the properties of the PDE-5 inhibitors, as well as those of other oral, sublingual, intracavernosal, and intraurethral ED drugs. This article reviews the diagnostic approach to the ED patient and the mechanisms of PDE-5 inhibition and discusses data from trials of PDE-5 inhibitors and the erectogenic dopaminergic agonist apomorphine.
