DescriptionLosartan (loe-SAR-tan) is used 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. High blood pressure may also
increase the risk of heart attacks. These problems may be less likely to occur
if blood pressure is controlled.
Losartan works by blocking the action of a substance in the body that causes
blood vessels to tighten. As a result, losartan relaxes blood vessels. This
lowers blood pressure.
