Abstract: 1. With a double-blind cross-over protocol, 20 hypertensive captopril-treated patients were studied by adding in a variable sequence a placebo and propranolol (80 mg three times a day) to their captopril regimen (200 mg three times a day), during periods each lasting 1 month. During captopril--placebo treatment their diastolic blood pressure remained elevated between 90 and 114 mmHg. 2. The additional administration of propranolol produced a significant hypotensive effect, but no alterations of the plasma angiotensin II and aldosterone concentrations and of the urinary aldosterone excretion occurred. The present data indicate that in captopril-treated patients the hypotensive effect of propranolol is achieved independently of changes in the plasma angiotensin II and aldosterone concentration. 3. The additional administration of propranolol also produced an increase in the serum potassium levels in the absence of any change in plasma aldosterone concentration or in the urinary aldosterone excretion.
