Which statement about using calcium channel blockers is true?

• A. They are commonly used to treat hypertension
• B. They cure hypothyroidism
• C. They prevent diabetes
• D. They cause immediate weight loss

Answer: (A)

Calcium channel blockers lower blood pressure by blocking calcium entry into vascular smooth muscle, which causes vasodilation and reduced peripheral resistance. That mechanism makes them a common and effective option for treating hypertension. They’re not cures for other conditions—hypothyroidism is treated with thyroid hormone replacement, not blood pressure medication. They don’t prevent diabetes, and they don’t cause immediate weight loss; some people may experience edema or weight gain as a side effect, but weight loss is not expected. Clinically, they’re also used for angina and certain arrhythmias, depending on the specific drug class.
