Angiotensin-converting enzyme inhibitors angioedema with

Angiotensin antagonists (Angiotensin-converting enzyme inhibitors) and ACE inhibitors lower blood pressure and are used to treat heart failure by causing the excretion of sodium and water. ACE inhibitors block the release of aldosterone. Aldosterone causes the retention of sodium. Cardiac output and heart rate remain unchanged. ACE inhibitors are administered to patients with elevated serum rennin levels. ACE inhibitors can cause angioedema in which the mouth, throat, lips, eyelids, hands, and feet swell.
