Abstract: | An effect of enalapril maleate on the activity of renin-angiotensin-aldosterone system and sympathetic reactivity, erythrocyte prostaglandin and sodium levels as well as blood beta-endorphin was investigated in 28 patients with the essential arterial blood hypertension. It was found that enalapril maleate significantly increased plasma renin activity, decreased plasma norepinephrine and its 24-hour excretion, and decreased erythrocyte beta-endorphin and sodium levels. Blood epinephrine and aldosterone levels and their daily excretion remained unchanged similarly to prostaglandins. The above results suggest that a decrease in sympathetic system activity and intracellular sodium concentration may play a role in the hypotensive action of enalapril maleate related to the inhibition of angiotensin II formation. |
