Angiotensin 2 receptor blockers are a type of medicine used to treat high blood pressure. This type of medicine also may be called angiotensin II receptor blockers.

Angiotensin is a chemical in the body that narrows the blood vessels. When blood vessels are narrow, blood pressure can go up.

Angiotensin 2 receptor blockers stop the action of angiotensin 2. As a result, the medicine helps relax the veins and arteries in the body, lowering blood pressure.

Several angiotensin 2 receptor blockers are available. Which one is best for you depends on your health and the condition being treated.

Examples of angiotensin 2 receptor blockers include:

• Azilsartan (Edarbi).
• Candesartan (Atacand).
• Irbesartan (Avapro).
• Losartan (Cozaar).
• Olmesartan (Benicar).
• Telmisartan (Micardis).
• Valsartan (Diovan).
