Question 9

Which of the following is the primary mechanism of action of Angiotensin-Converting Enzyme (ACE) inhibitors in treating hypertension?

Accepted Answer

C. Inhibiting the conversion of angiotensin I to angiotensin II — ACE inhibitors prevent the enzyme ACE from converting inactive angiotensin I to the potent vasoconstrictor angiotensin II. This leads to vasodilation and reduced aldosterone secretion, thus lowering blood pressure. Blocking beta-adrenergic receptors is the mechanism of beta-blockers, and direct vasodilation is characteristic of direct vasodilators. While they can lead to increased sodium/water excretion indirectly, it's not their primary mechanism.
