Angiotensin II is a very potent chemical that causes the muscles surrounding blood vessels to contract, thereby narrowing the blood vessels. Narrowing of blood vessels increases the pressure within the blood vessels and may lead to high blood pressure (hypertension). Reducing the binding and activity of angiotensin II leads to widening (dilation) of blood vessels and reduces blood pressure.
