Which type of medication is works by blocking the action of an enzyme that contracts blood vessels?

Medications that block the action of an enzyme responsible for contracting blood vessels are typically known as ACE inhibitors (Angiotensin-Converting Enzyme inhibitors). These drugs, such as lisinopril and ramipril, help lower blood pressure by preventing the formation of angiotensin II, a substance that narrows blood vessels. This action leads to vasodilation, reducing the workload on the heart and improving blood flow.
