Pharmacology & Mechanism of Action
Losartan Potassium is the first non-peptide orally active angiotensin II receptor blocker. It binds to the AT1 receptor found in many tissues (e.g. vascular smooth muscle, adrenal gland, kidneys and the heart) and reduces several important biological actions including vasoconstriction and the release of aldosterone responsible for hypertension.
