Forasartan, a specific angiotensin II antagonist, is used alone or with other antihypertensive agents to treat hypertension. Forasartan competes with angiotensin II for binding at the AT1 receptor subtype. As angiotensin II is a vasoconstrictor which also stimulates the synthesis and release of aldosterone, blockage of its effects results in a decreases in systemic vascular resistance. (en)
Forasartan competes with angiotensin II for binding at the AT<sub>1</sub> receptor subtype. As angiotensin II is a vasoconstrictor which also stimulates the synthesis and release of aldosterone, blockage of its effects results in a decreases in systemic vascular resistance. Also, since angiotensin causes vasoconstriction, the inhibition of this receptor decreases vasoconstriction, which consequently also decreases vascular resistnace. (en)
