Contents of the Package Leaflet
Losartán belongs to a group of medications called angiotensin II receptor antagonists.
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.
Losartán prevents angiotensin II from binding to these receptors, which causes the blood vessels to relax, thereby reducing blood pressure. Losartán reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.

Adult patients with high blood pressure
Normally, treatment starts with 50 mg of losartán (one losartán cinfa 50 mg tablet) once a day. The maximum blood pressure-lowering effect is achieved within 3-6 weeks of starting treatment.

Losartán can be administered with other medications that lower blood pressure (e.g., diuretics, calcium antagonists, alpha or beta blockers, and centrally acting medications), as well as with insulin and other medications frequently used to lower blood glucose levels (e.g., sulfonylureas, glitazones, and glucosidase inhibitors).
Adult patients with heart failure
Normally, treatment starts with 12.5 mg of losartán (one losartán cinfa 12.5 mg starting tablet) once a day. Normally, the dose is gradually increased 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), up to a maintenance dose determined by your doctor.

In the treatment of heart failure, losartán is normally 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.
Dosage in special patient groups
Your doctor may recommend a lower dose, especially when starting treatment in certain patients, such as those treated with high-dose diuretics, patients with liver failure, or patients over 75 years of age.
