What are -sartans used to treat?

-sartans, also known as angiotensin II receptor antagonists, are primarily used to treat high blood pressure, also referred to as hypertension. These medications work by blocking the action of angiotensin II, a hormone that constricts blood vessels, leading to decreased blood pressure. By inhibiting this hormone's effect, -sartans promote blood vessel relaxation and expansion, which helps to lower blood pressure effectively.

Additionally, these medications can also offer renal protection in patients with diabetes and can be beneficial in managing heart failure, but their main indication remains the treatment of high blood pressure. Thus, the correct association of -sartans primarily relates to their function in managing hypertension.
