Angiotensin Receptor Blocker

Angiotensin receptor blockers (ARBs), also known as angiotensin II receptor antagonists, AT1-receptor antagonists are a class of antihypertensive drug that modulates the renin–angiotensin system.

Angiotensin receptor blocker medication

These drugs block the angiotensin, which causes narrowing of the arteries. Angiotensin needs a receptor to constrict the blood vessel. ARBs block these receptors, thus blood vessels stays open and blood pressure drops.

Commonly prescribed ARBs on the market, include:

  1. Candesartan (brand name: Atacand)
  2. Eprosartan mesylate (brand name: Teveten)
  3. Irbesartan (brand name: Avapro)
  4. Losartan potassium (brand name: Cozaar)
  5. Telmisartan (brand name: Micardis)
  6. Valsartan (brand name: Diovan)
  7. Olmesartan (brand name: Benicar)
  8. Azilsartan medoxomil (brand name: Edarbi)

For what conditions ARBs can be useful?

Angiotensin receptor blocker (ARB) are the drugs of choice for patients with hypertension, heart failure, chronic kidney failure, heart attack (myocardial infarction that weakens the heart muscle), and prevent kidney failure in people with diabetes or hypertension. ARBs may prevent diabetes and reduce stroke risk in patients with hypertension and an enlarged heart. ARBs may prevent recurrence atrial fibrillation.
