1. What Losartán Kern Pharma is and what it is 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 present in blood vessels, causing them to narrow. This leads to an increase in blood pressure. Losartan blocks the binding of angiotensin II to these receptors, resulting in relaxation of the blood vessels, which in turn lowers blood pressure. Losartan slows the progression of renal impairment in patients with high blood pressure and type 2 diabetes.

Losartán Kern Pharma is used

• to treat patients with high blood pressure (hypertension),
• to protect the kidney in hypertensive patients with type 2 diabetes and laboratory test results indicating renal insufficiency and proteinuria ≥ 0.5 g per day (a condition in which the urine contains an abnormally high amount of protein),
• to treat patients with chronic heart failure, when your doctor considers that treatment with specific medicines called angiotensin-converting enzyme (ACE) inhibitors (medicines used to reduce 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 thickening of the left ventricle of the heart, losartan has been shown to reduce the risk of stroke (LIFE indication).

2. Before taking Losartán Kern Pharma

Do not take Losartán Kern Pharma

• if you are allergic (hypersensitive) to losartan or any of the other ingredients 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-lowering medicine containing aliskiren

Take special care with Losartán Kern Pharma

Tell your doctor if you are pregnant (or suspect you might be pregnant). Use of Losartán Kern Pharma is not recommended during early pregnancy, and must not be used after the third month of pregnancy, as it may cause serious harm to your baby when used from that stage onward (see Pregnancy section).

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

• if you have previously had angioedema (swelling of the face, lips, tongue, and/or throat) (see also section 4. Possible adverse effects),
• if you are experiencing excessive vomiting or diarrhea, which may cause excessive loss of fluid and/or salt from your body,
• if you are taking diuretics (medicines that increase the amount of fluid passing through your kidneys) or are on a low-salt diet that may lead to excessive loss of fluid 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 supplying your kidneys or if you have recently undergone a kidney transplant,
• if you have impaired liver function (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 life-threatening concomitant cardiac arrhythmias. Special attention is required if you are also being treated with a beta-blocker,
• if you have heart valve problems or heart muscle disorders,
• 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 hyperaldosteronism (a syndrome associated with excessive secretion of the hormone aldosterone by the adrenal gland due to adrenal dysfunction),
• if you are taking any of the following medicines used to treat high blood pressure (hypertension):
  • an angiotensin-converting enzyme inhibitor (ACE inhibitor) (e.g., enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes,
  • aliskiren.

Your doctor may 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 Losartán 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 as monotherapy without medical advice.

Use of other medicines

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

While being treated with Losartán Kern Pharma, take particular care if you are taking any of the following medicines:

• other medicines that lower blood pressure, as they may cause an additional decrease in blood pressure. Blood pressure may also be lowered by some of the following medicines/classes of medicines: tricyclic antidepressants, antipsychotics, baclofen, amifostine,
• medicines that retain potassium or may increase potassium levels (e.g., potassium supplements, potassium-containing salt substitutes, or potassium-sparing medicines such as certain diuretics [amiloride, triamterene, spironolactone] or heparin),
• non-steroidal anti-inflammatory drugs (NSAIDs), such as indomethacin, including COX-2 inhibitors (medicines 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 dose and/or take other precautions:

If you are taking an angiotensin-converting enzyme inhibitor (ACE inhibitor) or aliskiren (see also information under the headings “Do not take Losartán Kern Pharma” and “Take special care with Losartán Kern Pharma”).

If you have impaired kidney function, concomitant use of these medicines may lead to worsening of kidney function.

Medicines containing lithium should not be used in combination with losartan unless your doctor performs careful monitoring. Special precautionary measures (e.g., blood tests) may be appropriate.

Taking Losartán Kern Pharma with food and drink

Losartán Kern Pharma may be taken with or without food.

Pregnancy and breastfeeding

Pregnancy

Inform your doctor if you are pregnant (or suspect you might be pregnant). Your doctor will usually advise you to stop taking Losartán Kern Pharma before becoming pregnant or as soon as you know you are pregnant and will recommend an alternative medicine instead of Losartán Kern Pharma. Use of Losartán Kern Pharma is not recommended during early pregnancy, and must not be administered from the third month of pregnancy onward, as it may cause serious harm to your baby from that stage.

Breastfeeding

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

Consult your doctor or pharmacist before using any medicine.

Use in children and adolescents

3. How to take Losartán Kern Pharma

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

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

Patients with high blood pressure

Treatment usually starts with 50 mg of losartan (one tablet of Losartán Kern Pharma 50 mg) once daily. The maximum blood pressure-lowering effect is reached within 3 to 6 weeks after starting treatment. Afterwards, in some patients, the dose may be increased to 100 mg of losartan (two tablets of Losartán Kern Pharma 50 mg) once daily.

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

Treatment usually starts with 50 mg of losartan (one tablet of Losartán Kern Pharma 50 mg) once daily. Afterwards, the dose may be increased to 100 mg of losartan (two tablets of Losartán Kern Pharma 50 mg) once daily, depending on your blood pressure response.

Losartan tablets may be taken together with other blood pressure-lowering medicines (e.g. diuretics, calcium antagonists, alpha or beta blockers, and centrally acting agents), as well as with insulin and other medicines commonly used to reduce blood glucose levels (e.g. sulfonylureas, glitazones, and glucosidase inhibitors).

Patients with heart failure

Treatment usually starts with 12.5 mg of losartan once daily. The dose is usually gradually increased on a weekly basis (i.e., 12.5 mg daily during the first week, 25 mg daily during the second week, and 50 mg daily during the third week) up to a maintenance dose of 50 mg of losartan (one tablet of Losartán Kern Pharma 50 mg) once daily, depending on your condition.

In the treatment of heart failure, losartan is usually combined with a diuretic (a medicine that increases the amount of water passing through your kidneys) and/or digitalis (a medicine that helps your heart become 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 hepatic impairment, or patients over 75 years of age. The use of losartan is not recommended in patients with severe hepatic impairment (see section "Do not take Losartán Kern Pharma").
