The angiotensin receptor blockers (ARBs) are very effective and safe antihypertensive drugs. They exert their antihypertensive effect through blockage of the angiotensin II, type 1 receptor and quite possibly through stimulation by angiotensin II of the unoccupied type 2 receptor. Besides hypertension, the ARBs have been found recently to be of value in the treatment of heart failure and diabetic nephropathy. In addition, ARBs have emerged lately as being very effective and perhaps superior to other antihypertensive drugs in the prevention of de novo or recurrent strokes. Other actions that may account for their stroke-protective effects include their antiatherogenic, antidiabetic, antiplatelet aggregating, hypouricemic, and atrial antifibrillatory actions. All these actions make the ARBs a true pleiotropic class of drugs. Each of the foregoing effects will be discussed briefly in this concise review.
血管紧张素受体阻滞剂（ARBs）是非常有效且安全的抗高血压药物。它们通过阻断血管紧张素II 1型受体发挥抗高血压作用，很可能还通过血管紧张素II对未被占据的2型受体的刺激作用来实现。除高血压外，最近发现ARBs在治疗心力衰竭和糖尿病肾病方面具有价值。此外，ARBs最近已成为预防新发或复发性中风非常有效且可能优于其他抗高血压药物的药物。其他可能解释其对中风保护作用的作用包括其抗动脉粥样硬化、抗糖尿病、抗血小板聚集、降尿酸和心房抗纤颤作用。所有这些作用使ARBs成为一类真正具有多效性的药物。在这篇简要综述中将简要讨论上述每种作用。
