CHEITIO

1. what losartan potassium is and what it is used for

Losartan belongs to a group of medicines known as angiotensin-II receptor antagonists.

Angiotensin-II is a substance produced in the body which binds to receptors in blood vessels, causing them to tighten. This results in an increase in blood pressure. Losartan prevents the binding of angiotensin-II to these receptors, causing the blood vessels to relax which in turn lowers the blood pressure. Losartan slows the decrease of kidney function in patients with high blood pressure and type 2 diabetes.

Losartan potassium is used

• to treat patients with high blood pressure (hypertension) in adults and in children and adolescents 6 – 18 years of age.
• to protect the kidney in hypertensive type 2 diabetic patients with laboratory evidence of impaired renal function and proteinuria > 0.5 g per day (a condition in which urine contains an abnormal amount of protein).
• to treat patients with chronic heart failure when therapy with specific medicines called angiotensin-converting-enzyme inhibitors (ACE inhibitors, medicine used to lower high blood pressure) is not considered suitable by your doctor. If your heart failure has been stabilised with an ACE inhibitor you should not be switched to losartan.
• in patients with high blood pressure and a thickening of the left ventricle, Losartan potassium has been shown to decrease the risk of stroke (“LIFE indication”).

2. what you need to know before you take losartan potassiumdo not take losartan potassium if you are allergic to losartan or any of the other ingredients of this medicine (listed in section 6),

• if your liver function is severely impaired,
• if you are more than 3 months pregnant (It is also better to avoid losartan potassium in early pregnancy – see “Pregnancy and breast-feeding”),
• if you have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren.

Warning and precautions

Talk to your doctor or pharmacist before taking Losartan potassium.

You must tell your doctor if you think you are (or might become) pregnant. Losartan potassium is not recommended in early pregnancy, and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used at that stage (see pregnancy section).

It is important to tell your doctor before taking Losartan potassium:

• if you have had a history of angiooedema (swelling of the face, lips, throat, and/or tongue) (see also section 4 ‘Possible side effects’),
• if you suffer from excessive vomiting or diarrhoea leading to an extreme loss of fluid and/or salt in your body,
• if you receive diuretics (medicines that increase the amount of water that you pass out through your kidneys)

or are under dietary salt restriction leading to an extreme loss of fluid and salt in your body (see section 3 ‘Dosage in special patient groups’),

• if you are known to have narrowing or blockage of the blood vessels leading to your kidneys or if you have received a kidney transplant recently,
• if your liver function is impaired (see sections 2 „Do not take Losartan“ and 3 ‘Dosage in special patient groups’),
• if you suffer from heart failure with or without renal impairment or concomitant severe life threatening cardiac

arrhythmias. Special caution is necessary when you are treated with a B-blocker concomitantly,

• if you have problems with your heart valves or heart muscle,
• if you suffer from coronary heart disease (caused by a reduced blood flow in the blood vessels of the heart) or from cerebrovascular disease (caused by a reduced blood circulation in the brain),
• if you suffer from primary hyperaldosteronism (a syndrome associated with increased secretion of the hormone

aldosterone by the adrenal gland, caused by an abnormality within the gland),

• if you are taking any of the following medicines used to treat high blood pressure:

• – an ACE-inhibitor (for example enalapril, lisinopril, ramipril), in particular if you have diabetes-related kidney problems.

• – aliskiren

Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (e.g. potassium) in your blood at regular intervals,

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

Children and adolescents

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

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

Other medicines and Losartan potassium

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

Take particular care if you are taking the following medicines while under treatment with Losartan potassium :

• other blood pressure lowering medicines as they may additionally reduce your blood pressure. Blood pressure may also be lowered by one of the following drugs/ class of drugs: tricyclic antidepressants, antipsychotics, baclofene, amifostine,
• medicines which retain potassium or may increase potassium levels (e.g. potassium supplements, potassium-containing salt substitutes or potassium-sparing medicines such as certain diuretics [amiloride, triamteren, spironolactone] or heparin),
• non-steroidal anti-inflammatory drugs such as indometacin, including cox-2-inhibitors (medicines that reduce

inflammation, and can be used to help relieve pain) as they may reduce the blood pressure lowering effect of losartan.

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

Lithium containing medicines should not be taken in combination with losartan without close supervision by your doctor. Special precautionary measures (e.g. blood tests) may be appropriate.

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

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

Losartan potassium with food and drink

Losartan potassium may be taken with or without food.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

You must tell your doctor if you think you are (or might become) pregnant. Your doctor will normally advise you to stop taking Losartan potassium before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Losartan potassium. Losartan potassium is not recommended in early pregnancy, and must not be taken when more than 3 months pregnant, as it may cause serious harm to your baby if used after the third month of pregnancy.

Breastfeeding

Tell your doctor if you are breast-feeding or about to start breast-feeding. Losartan potassium is not recommended for mothers who are breast-feeding, and your doctor may choose another treatment for you if you wish to breastfeed, especially if your baby is newborn, or was born prematurely.

Driving and using machines

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

Losartan potassium is unlikely to affect your ability to drive or use machines. However, as with many other medicines used to treat high blood pressure, losartan may cause dizziness or drowsiness in some people. If you experience dizziness or drowsiness, you should consult your doctor before attempting such activities.

Losartan potassium contains lactose

Losartan potassium contains lactose monohydrate. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

3. how to take losartan potassium

Always take this medicine exactly as your doctor has told you. Check with your doctor if you are not sure. Your doctor will decide on the appropriate dose of Losartan potassium, depending on your condition and whether you are taking other medicines. It is important to continue taking Losartan potassium for as long as your doctor prescribes it in order to maintain smooth control of your blood pressure.

Adult patients with High Blood Pressure

Treatment usually starts with 50 mg losartan once a day. The maximal blood pressure lowering effect should be reached 3–6 weeks after beginning treatment. In some patients the dose may later be increased to 100 mg losartan once daily.

If you have the impression that the effect of losartan is too strong or too weak, please talk to your doctor or pharmacist.
