Forasartan selectively competes with angiotensin II for the binding of the angiotensin II (AT1) receptor subtype 1 in vascular smooth muscle, thereby blocking angiotensin II-mediated vasoconstriction resulting in vascular dilatation. In addition, the antagonistic effect on AT1 in the adrenal gland, prevents angiotensin II-induced stimulation of aldosterone synthesis and secretion by the adrenal cortex. This blocks the effects of aldosterone leading to an increase in sodium excretion and water and eventually a reduction in plasma volume and blood pressure."}]
