The treatment of erectile dysfunction has changed dramatically over the past two decades. The introduction of the oral agent sildenafil 2 years ago has revolutionized the treatment of men with compromised erections and has met with expected success and low morbidity. Sildenafil is effective in most men with erectile dysfunction in the general population and in select populations, such as men with spinal cord injury, diabetes mellitus, and patients who have had nerve-sparing radical prostatectomy. It is safe in the general population as well as in many men with cardiac disease. Other newer medications are in trial and may soon be available to supplement treatment with sildenafil. Oral phentolamine, apomorphine, newer phosphodiesterase type-5 inhibitors, and topical agents are currently in phase 3 trials. These agents, in addition to newer intraurethral and indictable agents, may assist men with erectile dysfunction and rescue those in whom sildenafil is ineffective or in whom untoward side effects of sildenafil reduce its effectiveness. The 21st century will witness many additional agents designed for specific patients with specific conditions causing erectile dysfunction. We can expect these oral agents, assisted by topical and injectable agents, to successfully restore erectile function in the majority of men suffering from erectile dysfunction.
