<unk>  is an angiotensin II receptor blocker this class of drug competes with angiotensin II for the angiotensin type I (AT1) receptors located throughout the body. Angiotensin II is a key component of the renin-angiotensin-aldosterone system which is responsible for vasoconstriction of blood vessels and promotes release of vasopressin from the posterior pituitary gland of the hypothalamus which helps promote water retention. Aldosterone is also released by the adrenal gland in response to angiotensin II which helps to reabsorb sodium which leads to water reabsorption that results in a rise in blood pressure. Blocking angiotensin II from binding to AT1 receptors will in turn prevent it from raising blood pressure which is why angiotensin II receptor blockers are useful medications in the treatment of blood pressure.<unk>  inhibits the NaCl co-transporters in the distal convoluted tubule of the nephrons located in the kidneys which are responsible for the excretion of sodium and chloride in exchange for reabsorption of calcium. Inhibition of the NaCl co-transporters result in water excretion which is believed to be the mechanism of action in diuresis and lowering blood pressure.
