Read this leaflet carefully before you start taking this medicine because it contains important information for you.
Contents of the pack and other information:
Losartan/Hydrochlorothiazide SUN is a combination of an angiotensin II receptor antagonist (losartan) and a diuretic (hydrochlorothiazide).
Angiotensin II is a substance produced in the body that binds to receptors present in blood vessels, causing them to narrow. This leads to an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, which causes the blood vessels to relax, thereby decreasing blood pressure. Hydrochlorothiazide causes the kidneys to eliminate more water and salts. This also helps to reduce blood pressure.
Losartan/Hydrochlorothiazide is indicated for the treatment of essential hypertension (high blood pressure).
Do not take Losartan/Hydrochlorothiazide SUN:
