What is the classification of Captopril?

Captopril is classified as an angiotensin-converting enzyme (ACE) inhibitor. This class of medications functions by inhibiting the enzyme that converts angiotensin I into angiotensin II, a potent vasoconstrictor. By blocking the formation of angiotensin II, Captopril promotes vasodilation, reduces blood pressure, and decreases the workload on the heart. This mechanism makes ACE inhibitors particularly useful in the management of hypertension and heart failure.

While other classifications exist for blood pressure medications, Captopril specifically acts by targeting the renin-angiotensin-aldosterone system (RAAS), which is a crucial pathway in regulating blood pressure and fluid balance. Understanding the role of Captopril as an ACE inhibitor aids in recognizing its therapeutic applications and how it differs from other classes such as beta-blockers, aldosterone inhibitors, and loop diuretics, which work through different mechanisms.
