1. What is LOSARTAN SILANES 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 results in an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, which causes the blood vessels to relax, resulting in a decrease in blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.

Losartan Silanes is used

• to treat patients with high blood pressure (hypertension).
• to protect the kidneys in hypertensive patients with type 2 diabetes and laboratory test results indicating kidney failure and proteinuria ≥ 0.5 g per day (a condition in which the urine contains an abnormal amount of protein).
• to treat patients with chronic heart failure, when your 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).

You should consult a doctor if it worsens or does not improve

2. BEFORE TAKING LOSARTÁN SILANES

Do not take Losartán Silanes

• if you are allergic (hypersensitive) to losartan or any of the other ingredients of Losartán Silanes,
• if your liver function is severely impaired,
• if you are pregnant for more than 3 months. (It is also best to avoid Losartán Silanes during the first months of pregnancy – see section Pregnancy).
• if you have diabetes or kidney failure and are being treated with a blood pressure-lowering medication containing aliskiren.

Warnings and precautions

Tell your doctor if you are pregnant (or if you think you may be pregnant). Your doctor will generally advise you to stop taking Losartán Silanes before you become pregnant or as soon as you know you are pregnant and will recommend that you take another medication instead of Losartán Silanes. Losartán Silanes is not recommended during the first trimester of pregnancy, and in no case should it be administered after the third month of pregnancy, as it may cause serious harm to your baby when administered from that time on.

Consult your doctor before starting to take Losartán Silanes:

• 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 causes 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 causes excessive loss of fluids or salt in your body (see section 3. Dosage in special patient groups),
• if you know you have narrowing or blockage of the blood vessels that go 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 Silanes and 3. Dosage in special patient groups),
• if you have heart failure with or without kidney failure or potentially life-threatening heart rhythm disorders. 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 an alteration of this gland).
• if you are taking any of the following medications 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 Silanes”.

Use of Losartán Silanes with other medications

Tell your doctor or pharmacist if you are taking or have recently taken any other medications, including those obtained without a prescription, herbal medicines, and natural products.

While being treated with Losartán Silanes, 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,
• medications that retain potassium or may increase potassium levels (e.g., potassium supplements, salt substitutes containing potassium, or potassium-sparing diuretics [e.g., amiloride, triamterene, spironolactone] or heparin),
• non-steroidal anti-inflammatory medications, 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.

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

Medications containing lithium should not be used in combination with losartan without your doctor performing careful monitoring. It may be appropriate to take special precautions (e.g., blood tests).

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 Losartán Silanes” and “Warnings and precautions”)

Taking Losartán Silanes with food and drinks

Losartán Silanes can be taken with or without food.

Pregnancy and breastfeeding

Losartán Silanes is not recommended during the first trimester of pregnancy, and in no case should it be administered after the third month of pregnancy, as it may cause serious harm to your baby when administered from that time on.

Breastfeeding

Tell your doctor if you are breastfeeding or plan to start breastfeeding. Losartán Silanes is not recommended during breastfeeding, and your doctor will choose another treatment for you if you want to breastfeed, especially if your baby is newborn or premature.

Consult your doctor or pharmacist before using any medication.

If you experience dizziness or drowsiness, consult your doctor before performing these activities.

3. HOW TO TAKE LOSARTÁN SILANES

Follow exactly the administration instructions of Losartán Silanes indicated by your doctor. In case of doubt, consult your doctor again.

Follow exactly the administration instructions of Losartán Silanes indicated by your doctor.

Your doctor will decide the appropriate dose of Losartán Silanes, depending on your condition and whether you are taking other medications. It is important to continue taking Losartán Silanes as long as your doctor prescribes it to maintain constant control of your blood pressure.

Patient with high blood pressure

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

If you think the action of Losartán is too strong or too weak, please inform your doctor or pharmacist.

Patient with high blood pressure and type 2 diabetes

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

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

Patient with heart failure

Normally, treatment starts with 12.5 mg of losartan once a day. Normally, the dose is gradually increased weekly (i.e., 12.5 mg per day during the first week, 25 mg per day during the second week, and 50 mg per day during the third week), up to a maintenance dose of 50 mg of losartan (one Losartán Silanes 50 mg tablet) once a day, depending on your condition.

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 failure, or patients over 75 years old. Losartan is not recommended in patients with severe liver failure (see section "Do not take Losartán Silanes").

Administration

Follow exactly the administration instructions of the medication contained in this leaflet or as indicated by your doctor. In case of doubt, consult your doctor.

The tablets should be taken with a glass of water. You should try to take your daily dose at approximately the same time every day. It is important that you continue taking Losartán Silanes until your doctor tells you otherwise.
