LORISTA
PolandThe medicine is used to treat high blood pressure in adults and children and adolescents (6–18 years), to protect the kidneys in patients with hypertension and type 2 diabetes, in the treatment of chronic heart failure, and in individuals with high blood pressure and thickening of the left ventricular wall, to reduce the risk of stroke.
Frequently asked questions
How should Lorista be taken?
Tablets should be swallowed with a glass of water. It is best to take the daily dose at the same time each day. The dosage is determined individually by a doctor depending on the patient's health status and age.
When should you not use this medicine?
Do not use the medicine if you are allergic to its ingredients, have severe liver dysfunction, or if the patient is taking aliskiren (in the case of diabetes or kidney disorders). The medicine must not be used after the 3rd month of pregnancy, and its use is not recommended during early pregnancy or while breastfeeding.
What are the possible side effects?
Dizziness, low blood pressure, weakness, fatigue, changes in kidney function, or excessively high potassium levels may occur frequently. Other possible symptoms include, among others, headache, drowsiness, shortness of breath, cough, nausea, or diarrhea. You must contact a doctor immediately if facial, lip, or throat swelling occurs (a severe allergic reaction).
Can Lorista be used with other preparations?
Particular caution should be exercised when using other blood pressure-lowering medicines, anti-inflammatory drugs (e.g., indomethacin), lithium, and potassium-sparing medicines. Simultaneous use with certain medicines that increase potassium levels (e.g., heparin) is not recommended. During treatment, avoid drinking grapefruit juice.
What should you do if you miss a dose or take too much of the medicine?
If you forget to take a dose, take it at the usual time, but do not take a double dose. In case of accidental ingestion of too many tablets, contact a doctor immediately, as this may cause excessively low blood pressure or heart rhythm problems.

1. What Lorista is and what it is used for
Lorista belongs to a group of medicines known as angiotensin II receptor antagonists.
Angiotensin II is a substance produced in the body that binds to receptors in blood vessel walls, causing them to constrict. This leads to increased blood pressure.
Losartan, the active substance in Lorista, prevents angiotensin II from binding to these receptors, resulting in blood vessel dilation and consequently lowering blood pressure.
Losartan slows down the deterioration of kidney function in patients with high blood pressure and type 2 diabetes.
Lorista is used:
- for the treatment of high blood pressure (hypertension) in adults and in children and adolescents aged 6 to 18 years;
- to protect the kidneys in patients with high blood pressure and type 2 diabetes, with laboratory-confirmed kidney dysfunction and proteinuria ≥0.5 g per day (a condition in which the urine contains an abnormal amount of protein);
- for the treatment of patients with chronic heart failure when treatment with certain medicines called angiotensin-converting enzyme (ACE) inhibitors is not considered appropriate by the doctor. If heart failure has been stabilized using an ACE inhibitor, the medication should not be switched to losartan;
- in patients with high blood pressure and left ventricular hypertrophy, because it has been shown that Lorista reduces the risk of stroke ("LIFE indication").
2. Important information before using Lorista
When not to use Lorista
CONFIDENTIAL
- if the patient is allergic to losartan or any of the other ingredients of this medicine (listed in section 6),
- during the third month of pregnancy (use of Lorista should also be avoided in early pregnancy – see section "Pregnancy and breastfeeding"),
- if the patient has severe liver function impairment,
- if the patient has diabetes or kidney problems and is being treated with a blood pressure-lowering medicine containing aliskiren.
Warnings and precautions
Before starting treatment with Lorista, discuss this with your doctor or pharmacist. Inform your doctor if you suspect (or are planning) pregnancy. Use of Lorista is not recommended during early pregnancy and must be avoided after the third month of pregnancy, as it may seriously harm the unborn child (see section "Pregnancy and breastfeeding"). It is important to inform your doctor before using Lorista:
- if the patient has ever experienced angioedema (swelling of the face, lips, throat, and/or tongue) (see also section 4 "Possible side effects"),
- if the patient is experiencing severe vomiting or diarrhoea leading to excessive loss of fluids and/or salts from the body,
- if the patient is taking diuretics (medicines that increase the amount of water excreted by the kidneys) or a low-salt diet, which may lead to excessive loss of fluids and salts from the body (see section 3 "Dosage in special patient groups"),
- if the patient has narrowing or blockage of the blood vessels leading to the kidneys or has recently undergone a kidney transplant,
- if the patient has liver function disorders (see sections 2 "When not to use Lorista" and 3 "Dosage in special patient groups"),
- if the patient has heart failure, with or without kidney problems, or severe, life-threatening cardiac arrhythmia. Particular caution is required when treating concomitantly with β-blockers,
- if the patient has heart valve or myocardial disorders,
- if the patient has ischemic heart disease (caused by reduced blood flow in the coronary blood vessels) or cerebrovascular disorders (caused by reduced blood circulation in the brain),
- if the patient has primary hyperaldosteronism (a syndrome caused by excessive aldosterone secretion from the adrenal glands due to adrenal abnormalities),
- if the patient is taking other medicines that may increase serum potassium levels (see section 2 "Lorista with other medicines"),
- if the patient is taking any of the following medicines used to treat high blood pressure:
- angiotensin-converting enzyme (ACE) inhibitors (e.g. enalapril, lisinopril, ramipril), particularly if the patient has kidney problems related to diabetes,
- aliskiren.
Your doctor may monitor kidney function, blood pressure, and serum electrolyte levels (e.g. potassium) at regular intervals. See also information under the heading "When not to use Lorista".
Children and adolescents
Studies on the use of losartan in children have been conducted. For additional information, please 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 efficacy has not been demonstrated in this age group.
CONFIDENTIAL
Lorista with other medicines
Inform your doctor or pharmacist about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take.
Inform your doctor if the patient is taking potassium supplements, salt substitutes containing potassium, potassium-sparing agents such as certain diuretics (amiloride, triamterene, spironolactone), or other medicines that may increase serum potassium levels (e.g. heparin, trimethoprim-containing medicines), as concomitant use with Lorista is not recommended.
Exercise particular caution when using the following medicines during treatment with Lorista:
- other medicines that lower blood pressure, as they may additionally reduce blood pressure. The following medicines/groups of medicines may also reduce blood pressure: tricyclic antidepressants, antipsychotics, baclofen, amifostine,
- non-steroidal anti-inflammatory drugs (NSAIDs), such as indomethacin, including COX-2 inhibitors (medicines that reduce inflammation and are used to relieve pain), as they may weaken the blood pressure-lowering effect of losartan. In patients with impaired kidney function, concomitant use of these medicines may lead to worsening of kidney function.
Concomitant use of lithium-containing medicines with losartan should not be undertaken without strict medical supervision. Special precautions (e.g. periodic blood tests) may be necessary. Your doctor may need to adjust the dose and/or take other precautionary measures:
- if the patient is taking an ACE inhibitor or aliskiren (see also information under the headings "When not to use Lorista" and "Warnings and precautions").
Taking Lorista with food and drink
Lorista may be taken independently of meals. Grapefruit juice should be avoided during treatment with Lorista.
Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or plans to become pregnant, she should consult her doctor or pharmacist before using this medicine.
Pregnancy
Inform your doctor if you suspect (or are planning) pregnancy. Your doctor will usually recommend discontinuing Lorista before planned pregnancy or immediately after pregnancy is confirmed and will recommend an alternative medicine. Use of Lorista is not recommended during early pregnancy and must be avoided after the third month of pregnancy, as it may seriously harm the unborn child.
Breastfeeding
Inform your doctor if you are breastfeeding or intend to breastfeed. Use of Lorista is not recommended during breastfeeding, especially when breastfeeding a newborn or premature infant. Your doctor may recommend an alternative medicine.
Driving and operating machinery
No studies on the effect on the ability to drive and operate machinery have been performed. It is unlikely that Lorista affects the ability to drive and operate machinery. However, as with many medicines used to treat high blood pressure, losartan may cause dizziness or
CONFIDENTIAL
drowsiness in some individuals. If dizziness or drowsiness occurs, consult your doctor before engaging in such activities.
Lorista contains lactose monohydrate
If the patient has been previously diagnosed with intolerance to certain sugars, the patient should consult their doctor before taking this medicine.
3. How to use Lorista
This medicine should always be used as directed by the physician or pharmacist. If in doubt,
consult your doctor or pharmacist.
Your doctor will determine the appropriate dose of Lorista based on your condition and other
medicines you are taking. It is important to continue taking Lorista for as long as your doctor
has instructed, in order to maintain consistent control of blood pressure.
Adult patients with high blood pressure
Treatment usually starts with a dose of 50 mg losartan (one tablet of Lorista 50 mg) once
daily. 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
losartan (two tablets of Lorista 50 mg) once daily.
If you feel that the effect of losartan is too strong or too weak, consult your
doctor or pharmacist.
Use in children and adolescents
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 aged 6 to 18 years
The recommended initial dose for patients weighing between 20 kg and 50 kg is 0.7 mg losartan per
kg body weight, given once daily (up to 25 mg of Lorista). Your 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 losartan (one tablet of Lorista 50 mg) once
daily. The dose may then be increased to 100 mg losartan (two tablets of Lorista 50
mg) once daily, depending on the blood pressure response achieved.
Losartan may be used concomitantly with other antihypertensive medicines (e.g. diuretics, calcium channel blockers, alpha- or beta-blockers, and centrally acting agents), as well as with insulin and other commonly used glucose-lowering medicines (e.g. sulfonylureas, glitazones, and alpha-glucosidase inhibitors).
Adult patients with heart failure
Treatment usually starts with a dose of 12.5 mg losartan (half a tablet of Lorista 25 mg) once
daily. This dose should usually be gradually increased at weekly intervals (i.e. 12.5 mg
daily during the first week, 25 mg daily during the second week, 50 mg daily during the third week, 100 mg daily during the fourth week, 150 mg daily during the fifth week) until the maintenance dose is reached, as directed by your doctor.
A maximum dose of 150 mg losartan (e.g. three tablets of Lorista 50 mg or one tablet of Lorista 100 mg and one tablet of Lorista 50 mg) once daily may be used.
In the treatment of heart failure, losartan is usually used in combination with diuretics (medicines
that increase the amount of water excreted by the kidneys) and/or digitalis glycosides (medicines that strengthen, increase the force of heart contractions and improve heart function) and/or beta-blockers.
Dosage in special patient groups
Your doctor may recommend a lower dose, especially when starting treatment in certain
patients, such as those taking high-dose diuretics, patients with impaired liver function, or patients over 75 years of age. Losartan should not be used in patients with severe liver impairment (see section "When not to use Lorista").
Method of administration
Tablets should be swallowed with a glass of water. Try to take your daily dose at the same time each day. It is important to continue taking Lorista for as long as your doctor has instructed.
Taking more Lorista than prescribed
If you accidentally take too many tablets, contact your doctor immediately. Symptoms of overdose include low blood pressure, rapid heartbeat, or possibly slow heartbeat.
Missed dose of Lorista
If you miss a dose, take the next dose at your usual time. Do not take a double dose to make up for a missed dose.
If you have any further questions about the use of this medicine, consult your doctor or pharmacist.
