LOSARTAN STADAFARMA 100 mg FILM-COATED TABLETS

1. What is Losartan Stadafarma 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 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 blood vessels to relax, thereby reducing blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.

Losartan is used

• to treat patients with high blood pressure (hypertension) in adults and in children and adolescents from 6 to 18 years old.
• to protect the kidneys in hypertensive patients with type 2 diabetes with clinical analyses indicating renal insufficiency and proteinuria ≥ 0.5 g per day (a disease in which the urine contains an abnormal amount of protein).
• to treat patients with chronic heart failure, when their doctor considers that treatment with specific medications called angiotensin-converting enzyme inhibitors (ACE inhibitors, medications used to lower high blood pressure) is not suitable. If your heart failure has been stabilized with an ACE inhibitor, you should not switch to losartan.
• in patients with high blood pressure and increased thickness of the left ventricle of the heart, losartan has been shown to reduce the risk of stroke (“LIFE indication”).

2. What you need to know before taking Losartan Stadafarma

Do not take losartan

• if you are allergic to losartan or any of the other ingredients of this medicine (listed in section 6),
• if you are pregnant for more than 3 months (it is also recommended to avoid losartan at the beginning of pregnancy - see Pregnancy),
• if your liver function is severely impaired,
• if you have diabetes or kidney insufficiency and are being treated with a blood pressure-lowering medication containing aliskiren.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Losartan Stadafarma.

You must inform your doctor if you think you are pregnant (or might be). Losartan is not recommended at the beginning of pregnancy, and it should not be taken if you are pregnant for more than 3 months, as it may cause serious harm to your baby if used during this period (see section Pregnancy).

It is essential to inform your doctor before taking losartan:

• if you have a history of angioedema (swelling of the face, lips, tongue, and/or throat) (see also section 4 “Possible side effects”),
• if you have excessive vomiting or diarrhea, which may cause excessive loss of fluid and/or salt from your body,
• if you are taking diuretics (medications that increase the amount of water that passes through your kidneys) or if you are on a low-salt diet that may cause excessive loss of fluids and salt in your body (see section 3 “Posology in special patient groups”),
• if you know you have narrowing or blockage of the blood vessels that supply your kidneys or if you have recently undergone a kidney transplant,
• if your liver function is impaired (see sections 2 “Do not take Losartan Stadafarma” and 3 “Posology in special patient groups”),
• if you have heart failure with or without kidney insufficiency or life-threatening cardiac arrhythmias. Special attention is necessary when being treated at the same time with a beta-blocker,
• if you have problems with the valves in your heart or with the heart muscle,
• if you have coronary heart disease (caused by reduced blood flow in the blood vessels of the heart) or cerebrovascular disease (caused by reduced blood circulation in the brain),
• if you have primary hyperaldosteronism (a syndrome associated with high secretion of the hormone aldosterone by the adrenal gland due to a disorder of this gland),
• if you are taking any of the following medications used to treat high blood pressure:
• • an angiotensin-converting enzyme inhibitor (ACE inhibitor) (e.g., enalapril, lisinopril, ramipril), especially if you have kidney problems related to diabetes
  • aliskiren.

Your doctor may need to monitor your kidney function, blood pressure, and blood electrolyte levels (e.g., potassium) at regular intervals.

See also the information under the heading “Do not take Losartan Stadafarma”.

• if you are taking other medications that may increase serum potassium levels (see section 2 “Other medications and Losartan Stadafarma”).

Consult your doctor if you experience abdominal pain, nausea, vomiting, or diarrhea after taking losartan. Your doctor will decide whether to continue treatment. Do not stop taking losartan on your own.

Children and adolescents

Losartan has been studied in children. For more information, talk to your doctor.

Losartan is not recommended for use in children with kidney or liver problems, as there is limited data available for these patient groups. Losartan is not recommended for use in children under 6 years old, as it has not been shown to be effective in this age group.

Other medications and Losartan Stadafarma

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medications.

Tell your doctor if you are taking potassium supplements, salt substitutes that contain potassium, or potassium-sparing medications such as certain diuretics (amiloride, triamterene, spironolactone) or other medications that may increase serum potassium levels (e.g., heparin, trimethoprim-containing medications), as combination with losartan is not recommended.

While being treated with losartan, be particularly cautious if you take any of the following medications:

• other medications that lower blood pressure, as they may cause additional blood pressure reduction. Blood pressure may also be lowered by some of the following medications/classes of medications: tricyclic antidepressants, antipsychotics, baclofen, amifostine,
• non-steroidal anti-inflammatory medications, such as indomethacin, including COX-2 inhibitors (medications that reduce inflammation and can be used to relieve pain), as they may reduce the blood pressure-lowering effect of losartan.

Your doctor may need to adjust your dose and/or take other precautions:

If you are taking an angiotensin-converting enzyme inhibitor (ACE inhibitor) or aliskiren (see also the information under the headings “Do not take Losartan Stadafarma” and “Warnings and precautions”).

If your kidney function is impaired, concomitant use of these medications may lead to worsening of kidney function.

Medications containing lithium should not be taken in combination with losartan without close monitoring by your doctor. Special precautions may be necessary (e.g., blood tests).

Taking Losartan Stadafarma with food and drinks

Losartan can be taken with or without food.

Pregnancy and breastfeeding

If you are pregnant, breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Pregnancy

You must inform your doctor if you think you are pregnant (or might be). Normally, your doctor will advise you to stop taking losartan before becoming pregnant or as soon as you know you are pregnant and will advise you to take another medication instead of losartan. Losartan is not recommended at the beginning of pregnancy, and it should not be taken if you are pregnant for more than 3 months, as it may cause serious harm to your baby if used from the third month of pregnancy.

Breastfeeding

Tell your doctor if you are breastfeeding or about to start breastfeeding. Losartan is not recommended for breastfeeding mothers, and your doctor may choose another treatment if you wish to continue breastfeeding. Especially if your child is a newborn or premature.

Driving and using machines

No studies have been conducted on the effects on the ability to drive and use machines.

It is unlikely that losartan will affect your ability to drive or use machines. However, like many medications used to treat high blood pressure, losartan may cause dizziness or drowsiness in some people. If you experience dizziness or drowsiness, consult your doctor before performing these activities.

Losartan Stadafarma contains lactose

This medication contains lactose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.

3. How to take Losartan Stadafarma

Follow the instructions for administration of this medication exactly as indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again. Your doctor will decide the appropriate dose of losartan, depending on your condition and whether you are taking other medications. It is essential to continue taking losartan as prescribed by your doctor to maintain constant blood pressure control.

Adult patients with high blood pressure

Normally, treatment starts with 50 mg of losartan (one losartan 50 mg tablet) once a day. The maximum blood pressure-lowering effect should be achieved within 3-6 weeks of starting treatment. Afterward, in some patients, the dose may be increased to 100 mg of losartan (two losartan 50 mg tablets or one losartan 100 mg tablet) once a day.

If you think the effect of losartan is too strong or too weak, inform your doctor or pharmacist.

Use in children and adolescents

Children under 6 years old

Losartan is not recommended for use in children under 6 years old, as it has not been shown to be effective in this age group.

Children between 6-18 years old

The recommended starting dose in patients weighing between 20 and 50 kg is 0.7 mg of losartan per kg of body weight, administered once a day (up to 25 mg of losartan). Your doctor may increase the dose if blood pressure is not controlled.

Other pharmaceutical forms of this medication may be more suitable for children; ask your doctor or pharmacist.

Adult patients with high blood pressure and type 2 diabetes

Normally, treatment starts with 50 mg of losartan (one losartan 50 mg tablet) once a day. Afterward, the dose may be increased to 100 mg of losartan (two losartan 50 mg tablets or one losartan 100 mg tablet) once a day, depending on the response of your blood pressure.

Losartan can be administered with other medications that lower blood pressure (e.g., diuretics, calcium antagonists, alpha or beta blockers, and centrally acting medications), as well as with insulin and other medications frequently used to lower blood glucose levels (e.g., sulfonylureas, glitazones, and glucosidase inhibitors).

Adult patients with heart failure

Normally, treatment starts with 12.5 mg of losartan (one losartan 12.5 mg tablet) once a day. Normally, the dose should be gradually increased, weekly (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), up to a maintenance dose determined by your doctor. A maximum dose of 150 mg of losartan (e.g., three losartan 50 mg tablets or one losartan 100 mg tablet and one losartan 50 mg tablet) once a day can be used.

In the treatment of heart failure, losartan is normally 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 insufficiency, or patients over 75 years old. Losartan is not recommended for use in patients with severe liver insufficiency (see section “Do not take Losartan Stadafarma”).

Administration

The tablets should be swallowed whole with a glass of water. You should try to take your daily dose at approximately the same time each day. It is essential to continue taking losartan as prescribed by your doctor.

The Losartan Stadafarma 50 mg tablet can be divided into equal doses.

If you take more Losartan Stadafarma than you should

If you accidentally take too many tablets, contact your doctor immediately. The symptoms of overdose are low blood pressure, increased heart rate, and possibly decreased heart rate.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medication and the amount ingested.

If you forget to take Losartan Stadafarma

If you accidentally miss a dose, simply take the next dose as usual. Do not take a double dose to make up for missed doses. If you have any other questions about the use of this medication, ask your doctor, pharmacist, or nurse.
