losartan potassium + hydrochlorothiazide
Losartan Hydrochlorothiazide Krka 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 in blood vessels, causing them to narrow. This leads to an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing blood vessels to widen and blood pressure to decrease. Hydrochlorothiazide works by increasing the amount of water and salt excreted in the urine. This also helps to lower blood pressure. Losartan Hydrochlorothiazide Krka is indicated for the treatment of primary hypertension (high blood pressure).
