Description

Lisinopril is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the work load of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys resulting in a stroke, heart failure, or kidney failure. Hypertension may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled .

Lisinopril works by blocking an enzyme in the body that is necessary to produce a substance that causes blood vessels to tighten. As a result, the blood vessels relax. This lowers blood pressure and increases the supply of blood and oxygen to the heart .

Lisinopril is also used in some patients after a heart attack. After a heart attack, some of the heart muscle is damaged and weakened. The heart muscle may continue to weaken as time goes by. This makes it more difficult for the heart to pump blood. Lisinopril may be started within 24 hours after a heart attack to increase survival rate .

In addition, lisinopril is used to treat congestive heart failure or may be used for other conditions as determined by your doctor .

This medicine is available only with your doctor’s prescription .
