Losartan Potassium is a non-peptide angiotensin II receptor antagonist that shows antihypertensive activity. This component binds to the angiotensin II receptor and blocks the binding of angiotensin II to the receptor. Thus, it promotes vasodilatation and counteracting the effects of aldosterone. Angiotensin II stimulates the adrenal cortex to secrete aldosterone that decreases the sodium excretion and increases potassium excretion, which acts as a vasoconstrictor in vascular smooth muscle.
