What class of drug is Carvedilol (Coreg)?

  1. Alpha blocker only

  2. Beta blocker only

  3. Alpha and beta blocker

  4. Diuretic

The correct answer is: Alpha and beta blocker

Carvedilol (Coreg) is classified as an alpha and beta blocker, meaning it blocks both alpha and beta receptors in the body. This allows it to lower blood pressure and improve heart function by reducing the effects of stress hormones, making it useful in treating conditions such as high blood pressure and heart failure. Option A is incorrect because carvedilol does block alpha receptors. Option B is incorrect because carvedilol does block beta receptors. Option D is incorrect because carvedilol is not a diuretic, which is a class of drugs that increase urine production.
