Abstract
Continuous 6-h infusions of the beta adrenergic blockers d,l-propranolol or oxprenolol significantly reduced plasma renin activity (PRA) and mean blood pressure in the resting rabbit and prevented the stimulatory effects of isoproterenol on renin release and heart rate. These actions were due to blockade of beta receptors, for the inactive isomer, d-propranolol, had no effect. Despite sustained high plasma concentrations of d,l-propranolol (0.2 μg/ml) in the unstimulated animal, PRA did not fall below 36% of control values, suggesting that basal renin secretion is maintained partly by factors other than beta adrenergic mechanisms.
