Angiotensin receptor blockers (ARBs) are typically prescribed for which primary condition?

Angiotensin receptor blockers (ARBs) are primarily prescribed for hypertension, or high blood pressure. They work by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict and raise blood pressure. By inhibiting this action, ARBs help to relax blood vessels, leading to a decrease in blood pressure. This class of medication is particularly important in the management of patients with hypertension, as lowering blood pressure helps to reduce the risk of cardiovascular events such as heart attack and stroke.

While ARBs can also be used in certain cases related to heart failure and might have beneficial effects in diabetic patients by protecting kidney function, their primary indication remains the treatment of hypertension. ARBs are not indicated for respiratory issues, which may involve different types of medications and treatment approaches. Thus, the focus on hypertension accurately reflects the primary role of ARBs in clinical practice.
