Forty-three patients suffering from hypertension of different origin (chronic renal failure, gout, or idiopathic) were treated with propranolol (121 +/- 12 mg q.d.) plus hydrochlorothiazide (50 mg q.d.) for 75 +/- 9 days. Blood pressure did not return to normal limits in 15 patients, who were continued on the same protocol plus 10 to 50 mg oxdralazine q.d. After an average of 68 +/- 35 days blood pressure fell from 180/110 mm Hg to 145/90 mm Hg without orthostatism, significant side effects, or changes in GFR. This combination seems particularly successful since propranolol will prevent the undesired rise in cardiac output due to oxdralazine as well as the activation of the renin-angiotensin axis due to diuretics. Thus, the antihypertensive properties of each agent will be enhanced by a reduction in side effects by the associated drug, resulting in optimal blood pressure control.
