Angiotensin 2 receptor blockers are a type of medicine used to treat high blood pressure. Other names for this type of medicine are:

• Angiotensin receptor blockers.
• Angiotensin II receptor blockers.
• ARBs.

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

ARBs stop the action of angiotensin 2. So the veins and arteries in the body relax. This lowers blood pressure.

Several ARBs are available. Which one is best for you depends on your health and the condition being treated.

Examples of ARBs include:

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