An Introduction to Medicines Containing Lisinopril

Lisinopril is the compound name for several medicines used to treat problems affecting the blood vessels and heart. Brand-name versions include Zestril^® (manufactured by AstraZeneca) and Prinivil^® (manufactured by Merck). Lisinopril is also available in generic form, sold under the name Lisinopril tablets.

Lisinopril is part of a class of drugs called angiotensin-converting enzyme inhibitors, or ACE inhibitors for short.

What Is Lisinopril Used For?

Lisinopril is licensed to treat a number of conditions, including:

High blood pressure (hypertension).
Congestive heart failure. Lisinopril is used as an add-on when treating people with congestive heart failure who are not reaching their goals with diuretics ("water pills") and digoxin (Digitek^®, Lanoxin^®) or digitoxin.
Acute heart attack. Lisinopril can be given to people within 24 hours of having a heart attack to increase chances of survival.

How Does This Drug Work?

As mentioned, lisinopril is part of a class of drugs called ACE inhibitors. ACE stands for angiotensin-converting enzyme. Lisinopril helps to block this enzyme, which is normally part of a reaction in the body that causes the blood vessels to narrow (constrict). By blocking this enzyme, lisinopril causes blood vessels to relax, which lowers blood pressure.
