What is Monopril?

Return to top

Monopril is a type of blood pressure-lowering medication known as an ACE inhibitor. It stops a chemical in your blood called angiotensin I from becoming a more powerful chemical that raises your blood pressure by making your blood vessels narrower and causing your body to retain salt and water. Monopril is used to lower your blood pressure when taken alone or in combination with other medications.

Monopril is also prescribed to help manage heart failure in combination with conventional therapy, including diuretics with or without digitalis.
