What class of medication does Eplerenone (Inspra) belong to?

Aldosterone blocker
Beta-blocker
Calcium channel blocker
Angiotensin-converting enzyme inhibitor

The correct answer is: Aldosterone blocker

Eplerenone (Inspra) belongs to the class of medications known as aldosterone blockers. This class of medication works by blocking the effects of aldosterone, a hormone that can cause edema and increase blood pressure. This is different from beta-blockers (B), which work by blocking the effects of adrenaline and reducing heart rate and blood pressure; calcium channel blockers (C), which prevent calcium from entering the cells of the heart and blood vessel walls, causing them to relax and lower blood pressure; and angiotensin-converting enzyme inhibitors (D), which inhibit the conversion of angiotensin I to angiotensin II, a hormone that can raise blood pressure. Thus, options B, C, and D are incorrect as they do not belong to the same class as Eplerenone.
