Package Leaflet: Information for the User
Losartan TecniGen 50 mg film-coated tablets EFG
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you:
Contents of the pack:
Losartan belongs to a group of medicines called angiotensin II receptor antagonists.
Angiotensin II is a substance produced in the body that binds to receptors in blood vessels, causing them to narrow. This results in an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing the blood vessels to relax, which in turn lowers blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.

It is not recommended to take Losartan TecniGen at the start of pregnancy, and in no case should it be taken after the third month of pregnancy, as it may cause serious harm to your baby when taken from that time on.

Patient with high blood pressure
Normally, treatment starts with 50 mg of losartan (one Losartan TecniGen 50 mg tablet) once a day. The maximum blood pressure-lowering effect is achieved within 3-6 weeks of starting treatment. After that, in some patients, the dose may be increased to 100 mg of losartan (2 Losartan TecniGen 50 mg tablets or 1 Losartan TecniGen 100 mg tablet) once a day.

Losartan tablets can be taken with other medicines that lower blood pressure (e.g., diuretics, calcium antagonists, alpha or beta blockers, and centrally acting agents), as well as with insulin and other medicines commonly used to lower blood sugar levels (e.g., sulfonylureas, glitazones, and glucosidase inhibitors).
Patient with heart failure
Normally, treatment starts with 12.5 mg of losartan 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, and 50 mg per day during the third week), up to a maintenance dose of 50 mg of losartan (1 Losartan TecniGen 50 mg tablet) once a day, depending on your condition.
In the treatment of heart failure, losartan is normally combined with a diuretic (a medicine that increases the amount of water that passes through your kidneys) and/or digitalis (a medicine 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 insufficiency, or patients over 75 years of age. It is not recommended to use losartan in patients with severe liver insufficiency (see section "Do not take Losartan TecniGen").
