Losartan and hydrochlorothiazide combination is also used to reduce the risk of stroke in patients with high blood pressure and enlargement of the heart.

Losartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes the blood vessels to tighten. Losartan relaxes the blood vessels and lowers the blood pressure. A lower blood pressure will increase the supply of blood and oxygen to the heart.
