Treatment of hypertension in diabetic men: problems with sexual dysfunction.

Hypertension occurs 2 to 3 times more frequently in diabetic persons than in nondiabetic persons. Care must be taken in treating hypertension in diabetic patients because the choice of antihypertensive agent may worsen the diabetic state or its complications or cause additional health problems for the patient. Sexual dysfunction is a common problem in diabetic patients; however, diabetes need not be the cause. Diabetic men with hypertension have an increased sensitivity to the side effect of sexual dysfunction, which occurs from the use of centrally acting antihypertensive agents. By using prazosin, an alpha 1-adrenergic blocking agent, this cause of sexual dysfunction was eliminated. The reasons for the increased prevalence of hypertension in diabetic patients are discussed and a rational approach is given for the treatment of elevated blood pressure in these individuals.
