What are ARBs commonly used to treat?

Angiotensin II receptor blockers (ARBs) are commonly used in the treatment of hypertension. They function by blocking the effects of angiotensin II, a hormone that causes blood vessels to constrict, which leads to increased blood pressure. By inhibiting this action, ARBs help to relax blood vessels, lowering blood pressure and reducing the workload on the heart.

In addition to hypertension, these medications may also be used for other conditions such as heart failure, to protect the kidneys in diabetic patients, and in cases of chronic kidney disease. However, their primary and most recognized indication remains the management of high blood pressure, making this choice the correct response.

Other options are specific to conditions that ARBs do not primarily treat. Diabetes manages blood sugar levels but is not directly treated with ARBs. Asthma is primarily treated with bronchodilators and anti-inflammatory medications, while hyperlipidemia involves managing cholesterol levels, typically through statins or other lipid-lowering agents, rather than ARBs.
