What Is Lisinopril 20mg?
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor that relaxes blood vessels so blood flows more easily and the heart works less hard. It is FDA-approved to treat high blood pressure in adults and children 6 and older, as an add-on treatment for heart failure, and to improve survival after a heart attack. Because people often compare lisinopril vs amlodipine, it helps to know they work differently — lisinopril blocks a hormone pathway, while amlodipine is a calcium channel blocker — and doctors sometimes prescribe lisinopril and amlodipine together. Lisinopril 20mg tablets are taken once daily and are available only with a prescription.
