ACEI: ACE inhibitor.

Definition of ACE (angiotensin converting enzyme)

ACE (angiotensin converting enzyme): The
angiotensins are peptides (substances smaller than proteins) that act
as vasoconstricting agents (causing blood vessels to narrow).
Narrowing the diameter of the blood vessels sends up the blood
pressure.
ACE converts angiotensin to its activated form (called angiotensin
II) enabling it to function.
The ACE inhibitors are drugs that inhibit the formation of
angiotensin II and are used for blood pressure control and
congestive heart failure. The ACE inhibitors include
benazepril (brand name: Lotensin), captopril (brand name: Capoten),
lisinopril (brand names: Zestril and Prinivil), quinapril (brand
name: Accupril), and ramipril (brand name: Altace).
