ACE Inhibitors- How do they



ACE Inhibitors- How do they work? Angiotensin II is a very potent chemical that causes the blood vessels to contract, thereby narrowing the vessels. This increases the pressure within the vessels causing high blood pressure (hypertension). Angiotensin II is formed from angiotensin I in the blood by the enzyme angiotensin converting enzyme (ACE). ACE inhibitors are medications that slow (inhibit) the activity of the enzyme ACE, which decreases the production of angiotensin II. As a result,
