Captopril-associated BP reduction occurs via lowered TPR without CO or HR changes; hypothesis-generating and should not change practice pending RCTs.
Does captopril alter hemodynamic, volume, and neurohumoral indices in patients with essential hypertension or renal arterial disease?
Captopril lowers blood pressure in hypertensive patients primarily by reducing total peripheral resistance without significantly altering cardiac output or heart rate.
Tarazi et al. (1980) studied this question.
