Effect of the angiotensin II antagonist saralasin on plasma aldosterone concentration and on blood pressure before and during sodium depletion in normal subjects.
The effect of the angiotensin II antagonist saralasin on plasma aldosterone, plasma angiotensin II and blood pressure was studied in six normal supine subjects both before and during sodium depletion. Before sodium depletion, infusion of saralasin produced no consistent changes; during sodium depletion, infusion of the angiotensin antagonist caused a fall in plasma aldosterone and an increase in plasma angiotensin II in each subject. It is concluded that angiotensin II plays a major part in stimulating aldosterone secretion during sodium depletion in man.
