Captopril-associated BP reductions correlate with baseline renin; hypothesis-generating for renin-guided use but should not yet change practice.
Does captopril reduce blood pressure and improve renal hemodynamics in patients with essential hypertension?
Captopril effectively lowers blood pressure in essential hypertension primarily via renin-angiotensin-aldosterone system blockade, offering favorable renal hemodynamic effects without causing tachycardia or volume retention.
Kiowski et al. (1982) studied this question.
