Losartan and Hydrochlorothiazide (Systemic)
Brand Names : Hyzaar
CategoryDescriptionLosartan (lo-SAR-tan) and hydrochlorothiazide (hye-droe-klor-oh-THYE-a-zide) is a combination medicine that belongs to the class of
medicines called high blood pressure medicines (antihypertensives). It is
used to treat high blood pressure (hypertension).
High blood pressure adds to the workload 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 a substance in the body that causes blood vessels
to tighten. As a result, losartan relaxes blood vessels. This lowers blood
pressure and increases the supply of blood and oxygen to the heart. Hydrochlorothiazide
helps reduce the amount of salt and water in the body by acting on the kidneys
to increase the flow of urine; this also helps to lower blood pressure.
This combination also may be used for other conditions as determined by
your doctor.
