What is a first-line antihypertensive drug combination?

• A. An ACE inhibitor or ARB combined with a beta-blocker
• B. A calcium channel blocker with a thiazide diuretic
• C. A beta-blocker with a thiazide diuretic
• D. An ACE inhibitor or ARB combined with a calcium channel blocker

Answer: (D)

Two drugs from different, proven first-line classes with complementary actions make a strong initial combination for hypertension. An ACE inhibitor or an ARB lowers BP by blocking the renin-angiotensin system, reducing vasoconstriction and aldosterone-mediated salt and water retention. A calcium channel blocker then relaxes vascular smooth muscle by inhibiting calcium entry, providing additional vasodilation. Using these together gives additive blood pressure reduction, excellent tolerability, and robust cardiovascular risk reduction shown in large trials. This pairing also offers practical advantages: ACE inhibitors and ARBs help protect kidney function and metabolic health in many patients, and they can lessen the edema that sometimes occurs with calcium channel blockers when used alone. Other common two-drug combos, like beta-blocker with a diuretic or a dihydropyridine CCB with a diuretic, are used in various scenarios but are not as universally endorsed as a first-line pairing for uncomplicated hypertension.
