Which of the following medications is NOT commonly used as a beta-blocker for hypertension?

The correct answer, Amlodipine, is not a beta-blocker; instead, it belongs to a class of medications known as calcium channel blockers. Amlodipine works by relaxing the blood vessels, which helps to lower blood pressure and improve blood flow. It is commonly used to treat hypertension and angina but does not affect the beta-adrenergic receptors, which is the mechanism by which beta-blockers operate.

In contrast, the other medications listed—Bystolic, Coreg, and Metoprolol—are all beta-blockers. These drugs work by blocking the effects of adrenaline on the beta-adrenergic receptors, leading to a decrease in heart rate and blood pressure. They are routinely prescribed for managing hypertension as well as various cardiac conditions.

Understanding the classifications and mechanisms of different antihypertensive medications is essential for managing patient care effectively in cardiovascular nursing practice.
