title: The relative antihypertensive potency of propranolol, oxprenolol, atenolol, and metoprolol given once daily. A double-blind, crossover, placebo-controlled study in ambulatory patients.
abstract: The antihypertensive effect of four beta-blocking agents given once daily was compared with that of placebo in a prospective, crossover, double-blind study of 150 patients. The preparations tested were slow-release propranolol hydrochloride, 160 mg, atenolol, 100 mg, slow-release oxprenolol hydrochloride, 160 mg, and metoprolol, 200 mg. Propranolol and atenolol produced a significant decline in lying, standing, and postexercise blood pressure and pulse rate values. The effects of oxprenolol and metoprolol were not significantly different from that of placebo.
