ABSTRACT: The number of medical therapies for patients with erectile dysfunction (ED) has increased in recent years because of our expanded understanding of the physiologic and neurologic causes of ED. Oral agents range from testosterone to antidepressants to phosphodiesterase inhibitors. Nitroglycerin and minoxidil have shown some effectiveness as topical agents. Alprostadil, which can be applied intraurethrally, is also effective as intracavernosal injection therapy. Prostaglandin E1 and papaverine are effective as intracavernosal injection agents. Some studies have shown that combined use of intracavernosal injection and oral therapy produces satisfactory erections.
