Mechanism of action

These drugs work by either blocking the enzyme ACE (angiotensin-converting enzyme) that produces angiotensin II, or by directly antagonizing the angiotensin II type 1 receptor (AT1). By reducing angiotensin II signaling, they cause vasodilation, decrease aldosterone secretion, and reduce sodium and water retention, leading to lower blood pressure and improved cardiac function.
