The outpatient treatment of refractory hypertension with minoxidil.
Minoxidil is a potent orally administered vasodilator under investigation for use in severe hypertension. Fifteen patients with moderate to severe hypertension refractory to conventional antihypertensive drugs were treated with minoxidil on an outpatient basis. Propranolol and furosemide were administered concomitantly to control reflex tachycardia and fluid retention. Good blood pressure control was achieved in all but one patient with the average supine mean arterial blood pressure falling from 140 mm Hg with conventional drugs to 106 mm Hg with minoxidil (P less than 0.0005). The major side effects of fluid retention (9/15), hirsutism (15/15), and tachycardia were adequately controlled in all but one patient. We conclude that minoxidil will be a valuable drug in the outpatient management of refractory hypertension.
