Angiotensin II receptor blockers

Angiotensin II receptor blockers (ARBs) are used to treat conditions such as high blood pressure and heart failure. Find out more about this class of medication.

By Mayo Clinic Staff

Angiotensin II receptor blockers (ARBs) help relax your blood vessels, which lowers your blood pressure and makes it easier for your heart to pump blood.

Angiotensin is a chemical in your body that affects your cardiovascular system in various ways, including narrowing your blood vessels. This narrowing can increase your blood pressure and force your heart to work harder.

Angiotensin II receptor blockers block the action of angiotensin II, allowing blood vessels to widen (dilate).

Examples of angiotensin II receptor blockers

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

Examples of angiotensin II receptor blockers include:

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