title: Beta-adrenergic receptor blocking drugs, hypertension and plasma renin.
abstract: 1 Propranolol and pindolol reduced both the blood pressure and plasma renin activity when given chronically to hypertensive patients. 2 There was no correlation between the fall in blood pressure and the fall in plasma renin activity. 3 Neither the basal nor the random plasma renin activity predicted the patients who would respond to beta-adrenergic receptor blocking drugs. 4 Oral propranolol reduced plasma renin activity but did not reduce blood pressure within 4 h of administration; oral pindolol reduced blood pressure but did not reduce plasma renin activity within 4 h of administration. 5 The reduction of blood pressure by propranolol and pindolol does not seem to be mediated by changes in plasma renin in most patients.
