The antihypertensive effect is caused by blocking angiotensin receptors. Angiotensin causes blood vessels to narrow , and the release of adosterone causes absorption of water and sodium and increases blood pressure. Therefore, blocking angiotensin 2 receptors counteracts all of the above and causes low blood pressure. 


This restricting effect results in a higher efficacy of the effect of angiotensin II on the heart and blood vessels, and fewer side effects than ACE inhibitors.
