Abstract
The suppression of renin release by angiotensin II (AII) (the so-called short feedback loop) is blunted in essential hypertension. To determine whether this abnormality is reversible, renin release was assessed in sodium-restricted essential hypertensives and normal controls: (a) during the administration of captopril for varying intervals and (b) following the infusion of graded doses of AII (0.3-3 ng/kg per min) before and after plasma levels of AII had been chronically reduced with captopril (25-50 mg every 6 h) for 70 h.
