Because as many as 25 percent of cases of erectile dysfunction are due to medication side effects,4 the patient's drug therapy should be reviewed. Common pharmacologic causes of this disorder include antihypertensive drugs, most notably the centrally acting agents, beta blockers and diuretics. Antipsychotic and antidepressant drugs are also frequently implicated. Other drugs that can cause erectile dysfunction include spironolactone (Aldactone), cimetidine (Tagamet) and finasteride (Proscar).5,7 Excessive alcohol intake, heroin use and cigarette smoking are also known causes (Table 2).4,7,8 Sildenafil was recently studied in a large series of diabetic men with erectile dysfunction and was found to be well tolerated and effective.22 In this randomized, controlled trial, 74 of 131 patients taking sildenafil reported improved erections compared with only 13 of 127 patients taking a placebo. The incidence of mild adverse effects was higher in the group taking sildenafil, but the incidence of cardiovascular events was similar in both groups.
