WHAT LOSARTAN POTASSIUM / HYDROCHLOROTHIAZIDE IS
AND WHAT IT IS USED FOR
Losartan Potassium / Hydrochlorothiazide is a combination of an angiotensin II receptor
antagonist (losartan) and a diuretic (hydrochlorothiazide).
Angiotensin II is a substance produced in the body which binds to receptors in blood vessels,
causing them to tighten. This results in an increase in blood pressure. Losartan prevents the
binding of angiotensin II to these receptors, causing the blood vessels to relax which in turn
lowers the blood pressure. Hydrochlorothiazide works by making the kidneys pass more water
and salt. This also helps to reduce blood pressure.
It is indicated for the treatment of essential hypertension (high blood pressure).
