What Is Monopril Used For?
How Does Monopril Work?Monopril is part of a class of drugs called ACE inhibitors. ACE stands for angiotensin-converting enzyme. Monopril helps to block the angiotensin-converting enzyme, which is normally part of a reaction in the body that causes blood vessels to narrow (constrict). By blocking this enzyme, Monopril causes blood vessels to relax, which can lower blood pressure.
By helping blood vessels relax, Monopril also increases the efficiency of the heart. This means that the heart does not have to work as hard and more blood can be pumped out to the rest of the body. Both of these effects are helpful for a person with congestive heart failure.
