Which of the following is a cardiovascular medication class used to lower blood pressure?

• A. Antihypertensives
• B. Cardiac glycoside
• C. Anticholesteral agents
• D. Beta blockers

Answer: (A)

Antihypertensives are the medicines designed to lower blood pressure. They work in разные ways—diuretics reduce blood volume, vasodilators widen blood vessels, ACE inhibitors and ARBs relax vessels, calcium channel blockers reduce vessel tension, and beta blockers lower heart rate and output. Among the options, this broad class is the one whose primary purpose is to lower blood pressure. Cardiac glycosides, like digoxin, mainly improve heart pumping in heart failure and some arrhythmias, not to reduce blood pressure. Anticholesteral (lipid-lowering) agents reduce cholesterol, not blood pressure. While beta blockers can lower blood pressure, they are a subtype of antihypertensives, so the best answer is the broad class that encompasses all methods to lower BP.
