Enalapril Uses

Congestive Heart Failure
Congestive heart failure (CHF) is a condition in which the heart cannot pump enough blood throughout the body. It does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way that it should.
 
For people with congestive heart failure, enalapril decreases blood pressure which makes the heart more efficient and allows more blood to be pumped from the heart. These effects of enalapril may cause a decrease in the symptoms of congestive heart failure -- including shortness of breath, fatigue, and swelling -- along with improved exercise tolerance and decreased hospitalizations. Enalapril is not a cure for congestive heart failure.
 
Left Ventricular Dysfunction
A heart attack or other chronic condition can damage the left side of the heart and cause it to pump blood less efficiently. This is called left ventricular dysfunction. With left ventricular dysfunction, a person does not necessarily have symptoms. This condition will often lead to heart failure.
 
For people who develop left ventricular dysfunction, taking enalapril on a daily basis can decrease the chances of developing CHF symptoms by 32 percent and decrease the chance of being hospitalized for chronic heart failure.
 

How Does Enalapril Work?

Enalapril is part of a class of drugs called angiotensin-converting enzyme inhibitors, or ACE inhibitors. Enalapril helps to block the angiotensin-converting enzyme, which is normally part of a reaction in the body that causes blood vessels to narrow (constrict). By blocking this enzyme, enalapril causes blood vessels to relax, which can lower blood pressure.
 
By helping blood vessels relax, enalapril also increases the efficiency of the heart. This means that the heart does not have to work as hard and more blood can be pumped out to the rest of the body. Both of these are helpful for a person with congestive heart failure.
