What is another effective antihypertensive drug combination?

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

Answer: (D)

Pairing an ACE inhibitor or ARB with a thiazide diuretic is especially effective because it combines two complementary mechanisms: the RAAS blocker dilates vessels and reduces aldosterone-driven sodium retention, while the thiazide reduces plasma volume and peripheral resistance. Their effects add up to produce a greater and more reliable drop in blood pressure than either agent alone. They also balance electrolyte changes, since ACE inhibitors/ARBs can raise potassium while thiazides tend to lower it. This combination has strong, well-supported use in hypertension guidelines as a first-line option, making it a widely recommended and dependable choice. Other combinations can be useful in certain situations, but they’re not as broadly favored as a default first-line pair. A beta-blocker can be effective but is less commonly preferred for uncomplicated hypertension. A calcium channel blocker with an ACE inhibitor is also effective, but the ACE/ARB plus thiazide combination has particularly robust guideline support and long-standing use as a standard approach.
