Learning About ARBs

Introduction

ARBs (angiotensin II receptor blockers) block a hormone that makes blood vessels narrow. As a result, the blood vessels relax and widen. This lowers blood pressure. ARBs also put more water and salt into the urine. This also lowers blood pressure.

ARBs can treat:

• High blood pressure.

• Coronary artery disease.

• Heart failure.

They also may be used to help your kidneys when you have diabetes.

Examples

• candesartan (Atacand)

• irbesartan (Avapro)

• losartan (Cozaar)

• olmesartan (Benicar)

• valsartan (Diovan)

This is not a complete list of all ARBs.
