Hong Kong – Researchers have now claimed that medications commonly prescribed to treat high blood pressure may also reduce patients’ colorectal cancer risk.
Angiotensin converting enzyme inhibitor (ACE-i) or angiotensin II receptor blocker (ARB) medications are prescribed for conditions such as heart failure, high blood pressure or heart disease. These medications inhibit or block angiotensin, a chemical that causes arteries to become narrow, the researchers said.
Doctors commonly prescribe these medications to people with high blood pressure to relax and open blood vessels, thereby lowering blood pressure.
The current study, published in the Hypertension, an American Heart Association journal, revealed that taking these medications may also reduce colorectal cancer risk.
“Our results provide new insights on a potential role of these medications for colorectal cancer prevention,” said study author Wai K Leung from the University of Hong Kong in Hong Kong.
“This is the first study to show the potential beneficial effects of ACE inhibitors and ARBs on colorectal cancer development, based on a large group of patients who were colorectal cancer-free at the beginning of the study,” Leung added.
