ACE Inhibitor

ACE inhibitors are a class of drugs used to treat high blood pressure, heart failure, diabetes, and some kidney diseases. ACE inhibitors work by blocking the action of an enzyme called angiotensin-converting enzyme (ACE). ACE is responsible for producing a hormone called angiotensin II, which causes blood vessels to narrow and increases blood pressure. By blocking the production of angiotensin II, ACE inhibitors relax the blood vessels and reduce blood pressure. This helps to prevent or delay the onset of serious medical conditions, such as stroke, heart attack, and kidney failure. ACE inhibitors are also sometimes used to treat other conditions, such as migraine headaches and some types of glaucoma.
