title: A study of the effects of atenolol and propranolol on renal function in patients with essential hypertension.
abstract: 1 The effects of propranolol and atenolol given in random order in a cross-over study to fifteen patients with essential hypertension have been studied. 2 Both drugs were effective in lowering blood pressure and side effects were not markedly different. 3 There was no change in exchangeable sodium or potassium or in total body potassium during treatment with either drug. 4 Ambulant plasma renin activity was reduced by both drugs but the fall in blood pressure was not related to initial plasma renin. 5 Despite equal mean reduction in blood pressure with the two drugs, creatinine clearance fell significantly only during treatment with propranolol. 6 These observations suggest that intra-renal beta 2-adrenoceptors may be of importance in the regulation of renal function.
