Losartán belongs to a group of medications known as angiotensin II receptor antagonists. Angiotensin II is a substance produced in the body that binds to receptors present in blood vessels, causing them to constrict. This results in an increase in blood pressure. Losartán prevents the binding of angiotensin II to these receptors, causing blood vessels to relax, which in turn reduces blood pressure. Losartán reduces the impairment of renal function in patients with high blood pressure and type 2 diabetes.rament of the function renal in patients with high blood pressure and type 2 diabetes.

Adult patients with high blood pressure
Typically, treatment begins with 50 mg of losartan (one losartan 50 mg tablet) once a day. The maximum blood pressure-lowering effect should be achieved within 3-6 weeks of starting treatment. Subsequently, in some patients, the dose may be increased to 100 mg of losartan (two losartan 50 mg tablets or one losartan 100 mg tablet) once a day.
If you estimate that the losartan effect is too strong or too weak, inform your doctor or pharmacist.

Other pharmaceutical forms of this medication may be more suitable for children; ask your doctor or pharmacist.
Adult patients with high blood pressure and type 2 diabetes
Typically, treatment begins with 50 mg of losartan (one losartan 50 mg tablet) once a day. Subsequently, the dose may be increased to 100 mg of losartan (two losartan 50 mg tablets or one losartan 100 mg tablet) once a day, depending on your blood pressure response.
Losartan can be administered with other medications that lower blood pressure (e.g., diuretics, calcium channel blockers, alpha or beta blockers, and central-acting medications), as well as with insulin and other medications frequently used to decrease blood glucose levels (e.g., sulfonylureas, glitazones, and glucosidase inhibitors).
Adult patients with heart failure
Typically, treatment begins with 12.5 mg of losartan (one losartan 12.5 mg tablet) once a day. Typically, the dose should be increased gradually, weekly (i.e., 12.5 mg per day during the first week, 25 mg per day during the second week, 50 mg per day during the third week, 100 mg per day during the fourth week, 150 mg per day during the fifth week), to a maintenance dose determined by your doctor. A maximum dose of 150 mg of losartan (e.g., three losartan 50 mg tablets or one losartan 100 mg tablet and one losartan 50 mg tablet) once a day may be used.
In heart failure treatment, losartan is typically combined with a diuretic (a medication that increases the amount of water that passes through your kidneys) and/or digitalis (a medication that helps your heart be stronger and more efficient) and/or a beta blocker.
Posology in special patient groups
Your doctor may recommend a lower dose, especially when starting treatment in certain patients, such as those treated with high doses of diuretics, patients with severe liver insufficiency, or patients over 75 years old.
