    Olmesartan Uses:

  • To control high blood pressure, enalapril is used alone or in conjunction with other drugs. It's also used to treat heart failure in conjunction with other drugs. Enalapril belongs to the angiotensin-converting enzyme (ACE) inhibitor class of drugs. It works by lowering certain chemicals that tighten blood vessels, allowing blood to circulate more freely and the heart to pump blood more efficiently. High blood pressure is a common disorder that can damage the brain, heart, blood vessels, kidneys, and other body organs if left untreated. Heart disease, a heart attack, heart failure, stroke, renal failure, vision loss, and other complications may also be caused by damage to these organs. Making lifestyle changes, in addition to taking medicine, can help you regulate your blood pressure.
