Effect of pindolol and propranolol on renal function of patients with hypertension

1 Pindolol and propranolol were administered orally in equipotent antihypertensive doses to 14 subjects with mild to moderate hypertension in an open cross-over study. 2 Pindolol caused a smaller decrease in plasma renin activity and heart rate than propranolol. 3 Glomerular filtration rate and effective renal plasma flow remained unchanged during therapy with either agent.
