Clonidine 34-43 renin Homo sapiens 140-145 6822130-2 1983 In patients with essential hypertension studied in a clinical research center, clonidine-induced decreases in diastolic blood pressure and in plasma renin activity (PRA) correlated closely after one day of treatment, but not thereafter. Clonidine 79-88 renin Homo sapiens 149-154 6822130-3 1983 Moreover, high-renin patients experienced significantly greater blood pressure decrements than low-renin patients during the first day of treatment, but subsequent blood pressure decreases were equal in the two groups, confirming that the sympathoinhibitory action of clonidine is probably independent of the renin-angiotensin system. Clonidine 268-277 renin Homo sapiens 15-20 6822130-7 1983 Thus, clonidine appears to have two separate actions on the renin-aldosterone axis: an early antirenin action primarily in high-renin patients, and a longer-term suppressive effect on aldosterone. Clonidine 6-15 renin Homo sapiens 60-65 6822130-7 1983 Thus, clonidine appears to have two separate actions on the renin-aldosterone axis: an early antirenin action primarily in high-renin patients, and a longer-term suppressive effect on aldosterone. Clonidine 6-15 renin Homo sapiens 97-102
