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 constrict. This leads to an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing blood vessels to dilate 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).
Before starting treatment with Losartan Hydrochlorothiazide Krka, the patient should discuss it with their doctor or pharmacist.
The patient should inform their doctor about pregnancy, suspected pregnancy or planned pregnancy. It is not recommended to take Losartan Hydrochlorothiazide Krka in early pregnancy and it should not be taken after the third month of pregnancy, as it may have a very harmful effect on the fetus if taken during this period of pregnancy (see "Pregnancy and breastfeeding").
The doctor may monitor kidney function, blood pressure and electrolyte levels (e.g. potassium) in the blood at regular intervals.
