What class of medication is first-line for long-term hypertension control?

• A. Beta-blockers
• B. Calcium channel blockers
• C. Diuretics
• D. ACE inhibitors

Answer: (D)

The main idea is that a medication class chosen for long-term hypertension control is valued not only for lowering blood pressure but also for protecting organs, especially the heart and kidneys. ACE inhibitors work by blocking the enzyme that converts angiotensin I to angiotensin II, a hormone that causes blood vessels to narrow. With this block, blood vessels relax (vasodilation), aldosterone release is reduced, and sodium and water retention decrease. The combined effect lowers peripheral resistance and plasma volume, helping blood pressure stay controlled over time.

But the benefits go beyond just lowering numbers. By reducing angiotensin II, ACE inhibitors slow the progression of kidney disease in people with diabetes and provide cardiovascular protection, lowering risks of events like heart failure progression and stroke. This makes them particularly advantageous for patients who have diabetes, chronic kidney disease, or established heart failure with reduced ejection fraction.

Be mindful of common concerns: a persistent cough can occur due to bradykinin buildup, and a small risk of angioedema exists; they can also raise potassium levels. They're generally avoided in pregnancy. While other drugs can be used as first-line in some patients, the organ-protective effects and broad applicability often make ACE inhibitors a strong initial choice for long-term hypertension management.
