About Losartan PotassiumAn angiotensin II receptor antagonist, Antihypertensive.Mechanism of Action of Losartan PotassiumIt is a competitive antagonist of angiotensin-2 at AT-1 receptor. It decreases peripheral resistance and lowers BP in hypertensive individuals. It blocks all overt actions of angiotensin-2 such as: - 1. Vasoconstriction, 2. Central & Peripheral sympathetic stimulus, 3. Release of aldosterone and adrenaline, 4. Salt and water reabsorption, 5. Central actions like thirst, vasopressin release, and growth promoting actions on heart and blood vessels.Pharmacokinets of Losartan PotassiumAbsorption: Well absorbed orally, but bioavailability is about 33% due to first pass metabolism.
Distribution: Distributed in to the body in a protein bound form, but there is no brain penetration.
Metabolism: Metabolized in the liver in to active carboxylic acid metabolite and other metabolites.
Excretion: Excreted through faeces and urine.
