Angiotensin II receptor blockers (ARBs)

Mode of action. Source: Wikipedia

These substances are AT1-receptor antagonists – that is, they block the activation of angiotensin II AT1 receptors. Blockade of AT1 receptors directly causes vasodilation, reduces secretion of vasopressin, reduces production and secretion of aldosterone, amongst other actions – the combined effect of which is reduction of blood pressure.

List of agents

Losartan (Cozaar)

Irbesartan ( Aprovel, Karvea, and Avapro)

Olmesartan (Benicar, Olmetec)

Candesartan (Blopress, Atacand, Amias, and Ratacand)

Valsartan (Diovan, Valtan, Valtan)
