Losartán belongs to a group of medications called angiotensin II receptor antagonists.

Angiotensin II is a substance produced in the body that binds to receptors present in blood vessels, causing them to constrict. This results in an increase in blood pressure. Losartán prevents the binding of angiotensin II to these receptors, causing blood vessels to relax, which in turn reduces blood pressure. Losartán reduces the worsening of renal function in patients with high blood pressure and type 2 diabetes.

Losartán Kern Pharma is used for

• treatment of patients with elevated blood pressure (hypertension),
• protection of the kidney in hypertensive patients with type 2 diabetes and laboratory test results indicating renal insufficiency and proteinuria ≥ 0.5 g per day (a situation in which the urine contains an abnormal amount of proteins),
• treatment of patients with chronic heart failure, when their doctor considers that treatment with specific medications, called angiotensin-converting enzyme inhibitors (ACE inhibitors, medications used to reduce elevated blood pressure) are not suitable. If their heart failure has been stabilized with an ACE inhibitor, they should not switch to losartán,
• in patients with elevated blood pressure and left ventricular hypertrophy of the heart, losartán has demonstrated that it reduces the risk of stroke (LIFE indication).

Do not take Losartán Kern Pharma

• if you are allergic (hypersensitive) to losartan or any of the other components of Losartán Kern Pharma,
• if your liver function is severely impaired,
• if you are more than 3 months pregnant. (It is best to avoid Losartán Kern Pharma during the first months of pregnancy – see Pregnancy section)
• if you have diabetes or kidney failure and are being treated with a blood pressure medication that contains aliskirén

Be especially careful with Losartán Kern Pharma

Inform your doctor if you are pregnant (or if you suspect you may be). Losartán Kern Pharma is not recommended for use at the beginning of pregnancy, and in no case should it be administered if you are more than three months pregnant, as it may cause serious damage to your baby when administered from that point onwards (see Pregnancy section).

Before taking Losartán Kern Pharma, it is essential to inform your doctor:

• if you have had 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 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 following a low-sodium diet that causes excessive loss of fluids or salt from your body (see section 3. Dosage in special patient groups),
• if you know you have narrowing or blockage of the blood vessels leading to your kidneys or if you have recently undergone a kidney transplant,
• if your liver function is altered (see sections 2. Do not take Losartán Kern Pharma and 3. Dosage in special patient groups),
• if you have heart failure with or without kidney failure or potentially fatal cardiac arrhythmias. Special attention is required when being treated at the same time with a beta-blocker,
• if you have problems with your heart valves or heart muscle,
• if you have coronary heart disease (caused by reduced blood flow in the heart's blood vessels) or cerebrovascular disease (caused by reduced blood circulation in the brain),
• if you have primary aldosteronism (a syndrome associated with elevated secretion of the aldosterone hormone by the adrenal gland due to an alteration of this gland)
• if you are taking any of the following medications used to treat high blood pressure (hypertension):
• • a converting enzyme inhibitor (ACEI) (e.g. enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes.
  • aliskirén

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

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

Consult your doctor if you experience abdominal pain, nausea, vomiting, or diarrhea after taking Losartán Kern Pharma. Your doctor will decide whether to continue treatment. Do not stop taking Losartán Kern Pharma in monotherapy.

Use of other medications

Inform your doctor or pharmacist if you are taking or have recently taken other medications, including over-the-counter medications, herbal remedies, and natural products.

While taking Losartán Kern Pharma, be particularly cautious if you are taking any of the following medications:

• other medications that lower blood pressure, as they may produce additional blood pressure reduction. Blood pressure may also decrease with some of the following medications/classes of medications: tricyclic antidepressants, antipsychotics, baclofen, amifostine,
• medications that retain potassium or that may increase potassium levels (e.g. potassium supplements, salt substitutes containing potassium, or potassium-sparing medications such as certain diuretics [amiloride, triamterene, spironolactone] or heparin),
• nonsteroidal anti-inflammatory drugs (NSAIDs), such as indomethacin, including COX-2 inhibitors (medications that reduce inflammation and may be used to relieve pain), as they may reduce the blood pressure-lowering effect of losartan.

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

If you are taking an ACEI or aliskirén (see also the information under the headings “Do not take Losartan Kern Pharma” and “Be especially careful with Losartán Kern Pharma”).

If your renal function is impaired, the concomitant use of these medications may worsen renal function.

Lithium-containing medications should not be used in combination with losartan without your doctor's careful monitoring. It may be necessary to take special precautions (e.g. blood tests).

Taking Losartán Kern Pharma with food and beverages

Losartán Kern Pharma can be taken with or without food.

Pregnancy and breastfeeding

Pregnancy

You must inform your doctor if you are pregnant (or if you suspect you may be). Your doctor will usually recommend that you stop taking Losartán Kern Pharma before becoming pregnant or as soon as you know you are pregnant and will recommend that you take another medication instead of Losartán Kern Pharma. Losartán Kern Pharma is not recommended for use at the beginning of pregnancy, and in no case should it be administered if you are more than three months pregnant, as it may cause serious damage to your baby when administered from that point onwards.

Breastfeeding

Inform your doctor if you are breastfeeding or plan to start. Losartán Kern Pharma is not recommended for use during breastfeeding, and your doctor will choose another treatment for you if you wish to breastfeed, especially if your baby is newborn or premature.

Consult your doctor or pharmacist before using any medication.

Use in children and adolescents

Losartán has been studied in children. For more information, speak with your doctor.

Driving and operating machinery

No studies have been conducted on the effects on the ability to drive and operate machinery.

It is unlikely that Losartán Kern Pharma will affect your ability to drive or operate machinery. However, as 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 engaging in these activities.

Important information about some of the components of Losartán Kern Pharma

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

Follow exactly the administration instructions for Losartán Kern Pharma as indicated by your doctor.

Your doctor will decide the appropriate dose of Losartán Kern Pharma based on your condition and if you are taking other medications. It is essential to continue taking Losartán Kern Pharma as prescribed by your doctor to maintain consistent blood pressure control.

Patients with high blood pressure

Typically, treatment begins with 50 mg of losartan (one Losartán Kern Pharma 50 mg tablet) once a day. The maximum blood pressure-lowering effect is achieved within 3-6 weeks of starting treatment. Subsequently, in some patients, the dose may be increased to 100 mg of losartan (two Losartán Kern Pharma 50 mg tablets) once a day.

If you estimate that the action of Losartán Kern Pharma is too strong or too weak, please inform your doctor or pharmacist.

Patients with high blood pressure and type 2 diabetes

Typically, treatment begins with 50 mg of losartan (one Losartán Kern Pharma 50 mg tablet) once a day. The dose may then be increased to 100 mg of losartan (two Losartán Kern Pharma 50 mg tablets) once a day depending on your blood pressure response.

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

Patients with heart failure

Typically, treatment begins with 12.5 mg of losartan once a day. The dose is usually increased gradually, weekly (i.e., 12.5 mg per day for the first week, 25 mg per day for the second week, and 50 mg per day for the third week), to a maintenance dose of 50 mg of losartan (one Losartán Kern Pharma 50 mg tablet) once a day, as needed.

In the treatment of heart failure, losartan is usually 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.

Posology in special patient groups

Your doctor may recommend a lower dose, especially when starting treatment in certain patients, such as those treated with high doses of diuretics, patients with liver insufficiency, or patients over 75 years old. Losartan is not recommended for use in patients with severe liver insufficiency (see "Do not take Losartán Kern Pharma").

Administration

The tablets should be taken with a glass of water. Try to take your daily dose at approximately the same time each day. It is essential to continue taking Losartán Kern Pharma until your doctor tells you otherwise.
