To determine if clinically effective doses of the antihypertensive agent captopril affected the
neuronal release of norepinephrine or baroreflex sensitivity, changes in plasma …

Captopril was administrated to 12 essential hypertensive patients with low or normal plasma
renin activity in order to evaluate its effectiveness in decreasing blood pressure and to …

Captopril (50 mg orally) produced a significant fall in systolic and diastolic blood pressure in
six normotensive sodium replete subjects, without a rise in heart rate. On captopril, there …

Angiotensin converting enzyme inhibitors reduce blood pressure without reflex tachycardia,
possibly as a result of enhanced hypothesis that this results from the removal of the …

Angiotensin II is a potent vasoconstrictor and has profound effects on autonomic neural
mechanisms in experimental animals. Human carotid baroreflex control of arterial pressure …

Objectives. The purpose of this study was to examine the effects of short-term captopril
therapy during sodium restriction on several markers of the sympathetic nervous system …

Removal of the facilitating effect of angiotensin II on sympathetic cardiovascular influences
may enhance the antihypertensive effect of angiotensin converting enzyme (ACE) inhibitors …

The cardiovascular effects of electrical stimulation of the posterior hypothalamus,
intravenous administration of norepinephrine (NE), and direct sympathetic nerve stimulation …

Short‐term hypertensive and hormonal effects of Captopril were studied in 26 hypertensive
patients. Blood pressure (BP) and heart rate were recorded in subjects in the supine position …

1. The reflex effects of intravenous phenylephrine, sodium nitroprusside or acute
haemorrhage in rabbits were examined as indices of baroreceptors reflex function. 2. The …
