Does Lisinopril Lower Blood Pressure?



A cardiologist put me on Lisinopril. How does this medicine lower blood pressure? How long should I take this medicine? Thanks.


Lisinopril is a drug called an ACE inhibitor. ACE stands for angiotensin converting enzyme and ACE is found in your blood vessels. ACE enzyme helps to make chemicals (angiotensin) which cause your blood vessels to constrict or tighten, raising your blood pressure. The ACE inhibitors like lisinopril block the production of angiotensin so your blood vessels do not tighten. The ACE inhibitors also stimulate other chemicals in your body which open up your blood vessels.  

Lisinopril will lower blood pressure but does not cure high blood pressure. You may continue to take this drug as long as you have hypertension.
