Package Leaflet: Information for the User
Losartan Pensa 12.5 mg Start coated tablets EFG
Read the package leaflet carefully before starting to take the medicine.
Contents of the package leaflet:
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 leads to an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, which causes the blood vessels to relax, resulting in a decrease in blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.

Patients with high blood pressure
Normally, treatment starts with 50 mg of losartan (one Losartan Pensa 50 mg tablet) once a day. The maximum blood pressure-lowering effect is achieved within 3-6 weeks of starting treatment. Afterward, in some patients, the dose may be increased to 100 mg of losartan (two Losartan Pensa 50 mg tablets) once a day.
If you think the effect of Losartan is too strong or too weak, please inform your doctor or pharmacist.

Losartan tablets can be administered with other blood pressure-lowering medications (e.g., diuretics, calcium antagonists, alpha or beta blockers, and centrally acting agents), as well as with insulin and other medications commonly used to lower blood sugar levels (e.g., sulfonylureas, glitazones, and glucosidase inhibitors).
Patients with heart failure
Normally, treatment starts with 12.5 mg of losartan (one Losartan Pensa 12.5 mg Start 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, and 50 mg per day during the third week), up to a maintenance dose of 50 mg of losartan (one Losartan Pensa 50 mg tablet) once a day, depending on your condition.
In the treatment of heart failure, losartan is usually 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 old. The use of losartan is not recommended in patients with severe liver failure (see section "Do not take Losartan Pensa").
