Angiotensin II is a very potent chemical produced by the body that causes the muscles surrounding blood vessels to contract, thereby narrowing the vessels. The narrowing of the vessels increases the pressure within the vessels causing
increases in 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, the blood vessels enlarge or dilate, and blood pressure is reduced. This lower blood pressure makes it easier for the heart to pump blood and can improve the function of a failing heart. In addition, the progression of kidney disease due to high blood pressure or diabetes is slowed.
What are some examples of ACE inhibitors
The following is a list of the ACE inhibitors that are available in the United
ACE inhibitors are used for controlling high blood pressure, treating heart failure, preventing strokes, and preventing kidney damage in people with hypertension or diabetes. They also improve survival after heart attacks. In studies, individuals with hypertension, heart failure, or prior heart attacks who were treated with an ACE inhibitor lived longer than patients who did not take an ACE inhibitor. Because they prevent early death resulting from hypertension, heart failure or heart attacks, ACE inhibitors are
an important group of drugs. Some individuals with hypertension do not respond sufficiently to ACE inhibitors alone. In these cases, other drugs often are used in combination with ACE inhibitors.
Are there any differences among the different types of ACE inhibitors?
ACE inhibitors are very similar. However, they differ in how they are eliminated from the body and their doses. Some ACE inhibitors need to be converted into an active form in the body before they work. In addition, some ACE inhibitors may work more on ACE that is found in tissues than on ACE that is present in the blood. The importance of this difference or whether one ACE inhibitor is better than another has not been determined.
