Angiotensin is a peptide hormone that causes vasoconstriction and a subsequent increase in blood pressure. It is part of the renin-angiotensin system, which is a major target for drugs that lower blood pressure. Angiotensin also stimulates the release of aldosterone, another hormone, from the adrenal cortex.
Angiotensin II also triggers a hormone that makes your body retain water. Having more fluid in your body, in a restricted space, will cause your blood pressure to rise. ACE inhibitors lower your blood pressure by reducing angiotensin II in your body. This allows your blood vessels to relax and widen, making it easier for blood to flow through. It also lowers the amount of water your body retains, which lowers your blood pressure.
