What initial effects does Enalapril Maleate have on blood pressure in hypertensive patients?

• A. Increases peripheral resistance
• B. Reduces total peripheral resistance
• C. Increases sodium retention
• D. Blocks renin secretion

Answer: (B)

Enalapril Maleate, an angiotensin-converting enzyme (ACE) inhibitor, works primarily by reducing total peripheral resistance, which is essential in its role as an antihypertensive agent. When administered to hypertensive patients, enalapril leads to vasodilation, which effectively lowers blood pressure. This occurs because the drug inhibits the conversion of angiotensin I to angiotensin II, a peptide that normally causes blood vessels to constrict. By blocking this process, enalapril helps to relax the blood vessels, decreasing overall vascular resistance and thereby lowering blood pressure. The reduction in total peripheral resistance is crucial for the management of hypertension, as it allows the heart to pump blood more easily, leading to improved cardiovascular health. The other options relate to mechanisms that do not accurately describe the primary effect of Enalapril Maleate in controlling blood pressure, making the choice of reducing total peripheral resistance the most appropriate outcome associated with its initial effects.
