Which drugs belong to the Angiotensin II receptor blockers (ARBs) class?

Angiotensin II receptor blockers (ARBs) are a class of medications that work by blocking the action of angiotensin II, a hormone that narrows blood vessels and increases blood pressure. By inhibiting this hormone, ARBs help to relax blood vessels, lower blood pressure, and provide other cardiovascular benefits.

Losartan, Olmesartan, and Valsartan are well-known examples of ARBs. Each of these drugs specifically targets the angiotensin II receptors, leading to their therapeutic effects in managing hypertension and other cardiovascular conditions. These medications are particularly useful for patients who cannot tolerate ACE inhibitors, another class of drugs that also modulate the renin-angiotensin system.

The other options listed consist of different categories of drugs that do not function as ARBs. For instance, the first option includes vasodilators like Hydralazine, which act through different mechanisms to lower blood pressure. The second option features alpha-1 adrenergic antagonists, which are primarily used for treating symptoms of benign prostatic hyperplasia and hypertension but do not target the angiotensin II receptors. Finally, the third option consists of beta-blockers, which primarily affect the heart and blood vessels but are distinct from ARBs in their mode of action
