1. WHAT IS PRESARTAN AND WHAT IS IT USED FOR
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 the blood vessel walls, causing them to narrow, which in turn increases blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing the blood vessels to relax, which in turn lowers blood pressure. Losartan slows down the deterioration of kidney function in patients with high blood pressure and type 2 diabetes.
Presartan is used:
- to treat patients with high blood pressure (hypertension)
- to protect the kidneys in patients with high blood pressure and type 2 diabetes with laboratory-confirmed kidney function impairment and proteinuria ≥ 0.5 g/day (a condition in which the urine contains an excessive amount of protein)
- to treat patients with chronic heart failure, when treatment with certain medicines called angiotensin-converting enzyme inhibitors (ACE inhibitors, medicines used to lower high blood pressure) is not considered appropriate by the doctor. If heart failure has been stabilized with an ACE inhibitor, it should not be replaced with losartan
- in patients with high blood pressure and thickening of the left ventricular wall, as losartan has been shown to reduce the risk of stroke (the "LIFE indication").
2. IMPORTANT INFORMATION BEFORE TAKING PRESARTAN
When not to take Presartan
- If the patient is allergic to losartan or any of the other ingredients of this medicine (listed in section 6).
- If the patient has severe liver function disorders.
- After the 3rd month of pregnancy (it is also recommended to avoid taking Presartan in early pregnancy - see "Pregnancy and breastfeeding").
- If the patient has diabetes or kidney function disorders and is being treated with a blood pressure-lowering medicine containing aliskiren.
Warnings and precautions
Before starting treatment with Presartan, the patient should discuss it with their doctor.
The patient should inform their doctor:
- if they have ever had angioedema - swelling of the face, lips, throat, and/or tongue (see also section 4 "Possible side effects");
- if they experience abdominal pain, nausea, vomiting, or diarrhea after taking Presartan, they should discuss it with their doctor. The doctor will decide on further treatment. The patient should not stop taking Presartan on their own;
- if they are taking diuretics (medicines that increase the amount of water excreted by the kidneys) or a low-salt diet leading to excessive fluid and salt loss from the body (see section 3 "Dosage in special patient groups");
- if they have narrowing or blockage of the blood vessels leading to the kidneys or if they have recently undergone a kidney transplant;
- if they have liver function disorders (see sections 2 "When not to take Presartan" and 3 "Dosage in special patient groups");
- if they have heart failure with or without kidney function disorders or co-existing severe life-threatening heart rhythm disorders. Particular caution is required when treating with beta-adrenolityki;
- if they have diseases of the heart valves or heart muscle;
- if they have coronary heart disease (caused by reduced blood flow in the heart's blood vessels) or cerebral vascular disease (caused by reduced blood circulation in the brain);
- if they have primary hyperaldosteronism (a syndrome associated with increased aldosterone hormone excretion by the adrenal glands, caused by adrenal gland disorders);
- if they are taking any of the following blood pressure-lowering medicines:
- angiotensin-converting enzyme inhibitor (ACE), such as enalapril, lisinopril, ramipril, especially if the patient has kidney function disorders associated with diabetes,
- aliskiren;
- if the patient is pregnant, suspects she may be pregnant, or plans to become pregnant. Presartan should not be taken during pregnancy, especially after the 3rd month, as it may seriously harm the fetus (see "Pregnancy and breastfeeding").
The doctor may monitor kidney function, blood pressure, and electrolyte levels (e.g., potassium) in the blood at regular intervals.
See also the information under the heading "When not to take Presartan".
Presartan and other medicines
The patient should tell their doctor or pharmacist about all medicines they are taking or have recently taken, as well as any medicines they plan to take.
Particular caution is required when taking the following medicines during treatment with Presartan:
- other blood pressure-lowering medicines, as they may further lower blood pressure. If another blood pressure-lowering medicine is added to losartan, the doctor may decide to monitor kidney function. Blood pressure may also be lowered by the following medicines/groups of medicines: tricyclic antidepressants, antipsychotics, baclofen, amifostine,
- potassium-sparing medicines or those that may increase potassium levels in the blood [e.g., potassium supplements, salt substitutes containing potassium, or potassium-sparing diuretics (such as amiloride, triamterene, spironolactone, eplerenone) or heparin],
- non-steroidal anti-inflammatory medicines such as indomethacin, including COX-2 inhibitors (medicines that reduce inflammation and may be used to reduce pain), as they may weaken the blood pressure-lowering effect of losartan. In patients with kidney function disorders, concomitant use of these medicines may lead to worsening of kidney function. Without close medical supervision, it is not recommended to take lithium-containing medicines in combination with losartan. It may be necessary to take special precautions (e.g., blood tests).
The doctor may need to adjust the dose and/or take other precautions if the patient is taking an ACE inhibitor or aliskiren (see also the information under the headings "When not to take Presartan" and "Warnings and precautions").
Presartan with food and drink
Presartan can be taken with or without food.
Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, thinks she may be pregnant, or plans to have a child, she should consult her doctor or pharmacist before taking this medicine.
Pregnancy
The patient should inform their doctor about suspected (or planned) pregnancy. The doctor will usually recommend stopping Presartan before planned pregnancy or as soon as pregnancy is confirmed and recommend taking another medicine instead of Presartan. Presartan should not be taken during pregnancy, especially after the 3rd month, as it may seriously harm the fetus.
Breastfeeding
The patient should inform their doctor about breastfeeding or intending to breastfeed. Presartan should not be taken during breastfeeding, especially in the case of breastfeeding a newborn or premature baby. The doctor may recommend taking another medicine.
Children and adolescents
No studies have been conducted on the use of losartan in children. For further information, the patient should consult their doctor.
Driving and using machines
No studies have been conducted on the effect of the medicine on the ability to drive vehicles and operate machinery. It is unlikely that Presartan will affect the ability to drive vehicles and operate machinery. However, as with many blood pressure-lowering medicines, losartan may cause dizziness or drowsiness.
In case of dizziness or drowsiness, the patient should consult their doctor before performing such activities.
Presartan contains lactose monohydrate
If the patient has been diagnosed with intolerance to some sugars, they should contact their doctor before taking the medicine.
Presartan contains sodium
The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means it is considered "sodium-free".
3. HOW TO TAKE PRESARTAN
This medicine should always be taken exactly as prescribed by the doctor. In case of doubts, the patient should consult their doctor or pharmacist.
The doctor will decide on the appropriate dose of Presartan, depending on the patient's condition and other medicines being taken. To maintain consistent blood pressure control, it is essential to continue taking Presartan as long as the doctor recommends.
Patient with high blood pressure
Treatment usually starts with a dose of 50 mg of losartan (e.g., one tablet of Presartan 50 mg) once a day. The maximum blood pressure-lowering effect should occur 3 to 6 weeks after starting treatment. In some patients, the dose may be increased to 100 mg of losartan (e.g., two tablets of Presartan 50 mg or one tablet of Presartan 100 mg) once a day.
Patient with high blood pressure and type 2 diabetes
Treatment usually starts with a dose of 50 mg of losartan (e.g., one tablet of Presartan 50 mg) once a day. The dose may be increased to 100 mg of losartan (e.g., two tablets of Presartan 50 mg or one tablet of Presartan 100 mg) once a day, depending on blood pressure changes.
Tablets containing losartan can be taken together with other blood pressure-lowering medicines (e.g., diuretics, calcium channel blockers, alpha- or beta-adrenolityki) and with insulin and other commonly used hypoglycemic medicines (e.g., sulfonylurea derivatives, glitazones, and glucosidase inhibitors).
Patient with heart failure
Treatment usually starts with a dose of 12.5 mg of losartan once a day. This dose is usually increased gradually at weekly intervals (i.e., 12.5 mg/day during the first week, 25 mg/day during the second week, 50 mg/day during the third week) until the usual maintenance dose of 50 mg (e.g., one tablet of Presartan 50 mg) once a day is reached, depending on the patient's condition.
In the treatment of heart failure, losartan is usually combined with diuretics (medicines that increase the amount of water excreted by the kidneys) and/or digitalis glycosides (medicines that strengthen the heart and increase its efficiency) and/or beta-adrenolityki.
Reducing the risk of stroke in patients with high blood pressure and left ventricular hypertrophy confirmed by ECG
Treatment usually starts with a dose of 50 mg of losartan once a day. Depending on blood pressure changes, hydrochlorothiazide may be added in a low dose and/or the dose of losartan may be increased to 100 mg once a day.
Dosage in special patient groups
In some patients, such as those taking high doses of diuretics, patients with liver function disorders, or patients over 75 years of age, the doctor may recommend reducing the dose, especially during the initial treatment phase. Losartan should not be taken by patients with severe liver function disorders (see "When not to take Presartan").
Administration
Tablets should be swallowed with a glass of water. The patient should try to take their daily dose of Presartan at the same time every day. It is essential to continue taking Presartan unless the doctor recommends otherwise.
Taking a higher dose of Presartan than recommended
In case of accidental ingestion of too many tablets or swallowing of several tablets by a child, the patient should immediately contact their doctor. Symptoms of overdose are low blood pressure, increased heart rate (decreased heart rate is possible).
Missing a dose of Presartan
If the patient has accidentally missed a daily dose, they should take the next dose as usual. The patient should not take a double dose to make up for the missed tablet.
Stopping treatment with Presartan
In case of any further doubts about taking this medicine, the patient should consult their doctor or pharmacist.
