Recently

Canadian scientists published an article warning that long-term use of angiotensin converting enzyme inhibitor（ACEIs）

a commonly used first-line antihypertensive drug

will increase the risk of lung cancer. The relationship between long-term chronic drug use of ACEIs and tumorigenesis has been paid much attention

and the literature shows that there is a risk of lung cancer. In this paper

we systematically review the potential risk of lung cancer of ACEIs drugs

and find that there is still much controversy at present. It is still necessary to conduct a retrospective study on more people who take ACEIs for a long time

and to carry out more indepth basic research to further clarify the mechanism of ACEIs on the occurrence of lung cancer. To provide reference for the safe use and pharmaceutical care of this kind of drugs.
