Potassium losartan
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 the walls of blood vessels, causes them to narrow. This results in an increase in 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, reducing 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, you should discuss it with your doctor or pharmacist.
You should inform your doctor if you suspect (or plan) pregnancy. The doctor will usually recommend stopping Lorista before planned pregnancy or immediately after confirming pregnancy and recommend taking another medicine instead of Lorista. Lorista should not be taken in early pregnancy and should not be taken after the 3rd month of pregnancy, as it may seriously harm the fetus (see section "Pregnancy and breastfeeding").
It is important to inform your doctor before taking Lorista:
Studies have been conducted on the use of losartan in children. For more information, you should consult your 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
You should tell your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take.
You should tell your 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 concomitant use with Lorista is not recommended.
Special caution is required when taking the following medicines during treatment with Lorista:
Lorista can be taken with or without food.
You should avoid drinking grapefruit juice while taking Lorista.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, you should ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
You should inform your doctor if you suspect (or plan) pregnancy. The doctor will usually recommend stopping Lorista before planned pregnancy or immediately after confirming pregnancy and recommend taking another medicine instead of Lorista. Lorista should not be taken in early pregnancy and should not be taken after the 3rd month of pregnancy, as it may seriously harm the fetus.
Breastfeeding
You should inform your doctor if you are breastfeeding or planning to breastfeed. Lorista is not recommended during breastfeeding, especially in newborns or premature babies. The doctor may recommend taking another medicine.
No studies have been conducted on the effects on the ability to drive and use machines. It is unlikely that Lorista will affect the ability to drive and use machines. However, as with many medicines used to treat high blood pressure, losartan may cause dizziness or drowsiness.
CONFIDENTIAL
In case of dizziness or drowsiness, you should consult your doctor before performing such activities.
If you have been diagnosed with an intolerance to some sugars, you should contact your doctor before taking this medicine.
This medicine should always be taken exactly as prescribed by your doctor or pharmacist. If you are unsure, you should ask your doctor or pharmacist.
The doctor will determine the appropriate dose of Lorista, depending on your condition and the other medicines you are taking. It is important to take Lorista for as long as the doctor has prescribed it, in order to maintain constant blood pressure control.
Adult patients with high blood pressure
Treatment usually starts with a dose of 50 mg of losartan (one 50 mg Lorista tablet) once a day. The maximum blood pressure-lowering effect should occur within 3 to 6 weeks after starting treatment. In some patients, the dose may then be increased to 100 mg of losartan (two 50 mg Lorista tablets) once a day.
If you feel that the effect of losartan is too strong or too weak, you should consult your doctor or pharmacist.
Children under 6 years of age
Lorista is not recommended for use in children under 6 years of age, as its efficacy has not been demonstrated in this age group.
Children from 6 to 18 years of age
The recommended initial dose in patients with a body weight of 20 kg to 50 kg is 0.7 mg of losartan per kg of body weight, given once a day (up to 25 mg of Lorista). The doctor may increase the dose if blood pressure is not well controlled.
Adult patients with high blood pressure and type 2 diabetes
Treatment usually starts with a dose of 50 mg of losartan (one 50 mg Lorista tablet) once a day. The dose may then be increased to 100 mg of losartan (two 50 mg Lorista tablets) once a day, depending on the achieved change in blood pressure.
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 that lower blood sugar levels (e.g. sulfonylurea derivatives, glitazones, and glucose 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 prescribed by the doctor.
A maximum dose of 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 is allowed.
CONFIDENTIAL
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").
The tablets should be swallowed with a glass of water. You should try to take your daily dose of Lorista at the same time every day. It is important to take Lorista for as long as the doctor has prescribed it.
In case of accidental ingestion of too many tablets, you should immediately contact your doctor. Symptoms of overdose are low blood pressure, rapid heart rate, and possibly slow heart rate.
In case of a missed dose, you should take the next dose at the usual time. You should not take a double dose to make up for a missed dose.
If you have any further questions about taking this medicine, you should ask your doctor or pharmacist.
Like all medicines, Lorista can cause side effects, although not everybody gets them.
In case of the following side effects, you should stop taking losartan and immediately consult your doctor or go to the emergency department of the nearest hospital:
