Losartan potassium
Lorista belongs to a group of medicines called angiotensin II receptor antagonists.
Angiotensin II is a substance produced in the body that, by binding to receptors in blood vessel walls, causes them to narrow. This results in increased blood pressure.
Losartan, the active substance of Lorista, prevents angiotensin II from binding to these receptors, causing blood vessels to widen and, as a result, lowering blood pressure.
Losartan slows down the deterioration of kidney function in patients with high blood pressure and type 2 diabetes.
Lorista is used:
CONFIDENTIAL
Before starting to take Lorista, the patient should discuss it with their doctor or pharmacist.
The patient should inform their doctor about suspected or planned pregnancy. The doctor will usually recommend stopping Lorista before planned pregnancy or as soon as pregnancy is confirmed, and recommend taking a different medicine instead of Lorista. Lorista should not be taken in early pregnancy and must not be taken after the third month of pregnancy, as it may seriously harm the baby (see section "Pregnancy and breastfeeding").
It is essential to inform the doctor before taking Lorista:
Studies have been conducted on the use of losartan in children. For more information, patients should consult their doctor.
Losartan is not recommended for use in children and adolescents with kidney or liver function disorders due to limited data available for these patient groups. Losartan is not recommended for use in children under 6 years of age, as its efficacy has not been demonstrated in this age group.
CONFIDENTIAL
Patient should tell their doctor or pharmacist about all medicines they are taking, have recently taken, or might take.
Patient should tell their doctor about any potassium supplements, salt substitutes containing potassium, potassium-sparing diuretics (e.g., amiloride, triamterene, spironolactone), or other medicines that may increase potassium levels in the blood (e.g., heparin, trimethoprim-containing medicines), as co-administration with Lorista is not recommended.

Adult patients with high blood pressure

In case of feeling that the effect of losartan is too strong or too weak, patient should consult their doctor or pharmacist.

Treatment usually starts with a dose of 50 mg of losartan (one 50 mg Lorista tablet) once a day. The dose may be increased to 100 mg of losartan (two 50 mg Lorista tablets) once a day, depending on the blood pressure response.
Losartan can be taken with other blood pressure-lowering medicines (e.g., diuretics, calcium channel blockers, alpha- or beta-blockers) and with insulin and other commonly used medicines to lower blood glucose levels (e.g., sulfonylurea derivatives, glitazones, and glucosidase inhibitors).
Adult patients with heart failure
Treatment usually starts with a dose of 12.5 mg of losartan (half a 25 mg Lorista tablet) once a day. This dose is usually increased gradually at weekly intervals (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) until the maintenance dose is reached, as recommended by the doctor.
The maximum recommended dose is 150 mg of losartan (e.g., three 50 mg Lorista tablets or one 100 mg Lorista tablet and one 50 mg Lorista tablet) once a day.

In the treatment of heart failure, losartan is usually taken with diuretics (medicines that increase the amount of water excreted by the kidneys) and/or digitalis glycosides (medicines that strengthen the heart and improve its efficiency) and/or beta-blockers.
The doctor may recommend a lower dose, especially when starting treatment in certain patients, such as those taking high doses of diuretics, patients with liver function disorders, or patients over 75 years of age. Losartan should not be taken by patients with severe liver function disorders (see section "When not to take Lorista").
