1. What Losartan Potassium Tablets are and what they are 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 blood vessels to relax which in turn lowers the blood pressure. Losartan slows the decrease of kidneys function in patients with high blood pressure and type 2 diabetes. Losartan Potassium Tablets are used:

•    to treat patients with high blood pressure (hypertension) in adults, and in children and adolescents between 6 and 18 years of age

•    to protect the kidneys in hypertensive type 2 diabetic patients with laboratory evidence of impaired renal function and proteinuria > 0.5g per day (a condition in which the 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, medicines 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 Potassium Tablets

•    in patients with high blood pressure and a thickening of the left ventricle, Losartan Potassium Tablets have been shown to decrease the risk of stroke (“LIFE indication”).

2. What you need to know before you take Losartan Potassium Tablets

Do not take Losartan Potassium Tablets:

•    if you are allergic (hypersensitive) to losartan or to any other ingredients in this medicine (see section 6. Contents of the pack and other information)

•    if your liver function is severely impaired

•    if you are more than three months pregnant. (It is also better to avoid taking Losartan Potassium Tablets in early pregnancy - see also ‘Pregnancy and breastfeeding')

•    if you have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren.

Warnings and precautions

You must tell your doctor if you think you are (or might become) pregnant. Losartan Potassium Tablets are not recommended in early pregnancy, and must not be taken if you are more than three months pregnant, as it may cause serious harm to your baby if used at that stage (see ‘Pregnancy and breastfeeding')

It is important to tell your doctor before taking Losartan Potassium Tablets:

•    if you have had a history of angioedema (swelling of the face, lips, throat, and/or tongue (see also section 4 ‘Possible side effects').

•    if you suffer from excessive vomiting and/or diarrhoea leading to an extreme loss of fluid and/or salt in your body

•    if you take diuretics (water pills), medicines used to increase the amount of urine produced (see also section 3. How to take Losartan Potassium tablets) 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 your liver function is impaired (see also section above “Do not take Losartan Potassium tablets if you” and 3 ‘Dosage in special patient groups')

•    if you are known to have a narrowing or blockage of the blood vessels leading to your kidneys, or if you have had a kidney transplant recently

•    if you suffer from heart failure with or without kidney problems or concomitant severe life threatening irregular heartbeat. Special caution is necessary when you are treated with a beta-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 have 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-inh bitor (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 Tablets:”.

Other medicines and Losartan Tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those 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 Tablets:

•    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, baclofen, 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, [including amiloride, triamterene or 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 Losartan Tablets” and “Warnings and precautions”).

Losartan Potassium Tablets with food and drink

It is important to continue taking Losartan Potassium Tablets as long as your doctor prescribes them in order to maintain smooth control of your blood pressure.

Adult Patients with high blood pressure

The usual starting dose is one 50 mg tablet once a day. The maximal blood pressure lowering effect should be reached three to six weeks after beginning treatment. In some patients the dose may later be increased to 100mg losartan (two 50mg tablets) once daily. If you have the impression that the effect of losartan is too strong or weak, please talk to your doctor or pharmacist.

Use in Children or adolescents (6 to 18 years old)

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

Adult patients with high blood pressure and type 2 diabetes

The usual starting dose is one 50 mg tablet once a day. The dose may later be increased to two 50 mg tablet or one 100 mg tablet) once a day depending on your blood pressure response. Losartan may be administered with other blood pressure lowering medicines (e.g. diuretics, calcium channel blockers, alpha- or beta-blockers, and centrally acting agents) as well as with insulin and other commonly used medicines that decrease the level of glucose in the blood (e.g. sulfonylurease, glitazones and glucosidase inhibitors).

Adult Patients with heart failure

The usual starting dose is 12.5mg losartan once a day. Generally, the dose should be increased weekly step-by-step (i.e., 12.5mg daily during the first week, 25mg daily during the second week, 50mg daily during the third week, 100mg daily during the fourth week, 150mg daily during the fifth week) up to the maintenance dose as determined by your physician. A maximum dose of 150mg losartan (for example, three tablets of Losartan Potassium 50mg Tablets or one tablet each of Losartan Potassium 100mg Tablets and Losartan Potassium 50mg Tablets) once daily may be used.

Doses smaller than 25 mg cannot be obtained with these Losartan Potassium Tablets. For a dose not achievable with this medicine, other medicinal products containing losartan potassium should be used. In the treatment of heart failure, losartan is usually combined with a diuretic (medicine that increases the amount of water that you pass out through your kidneys) and/or digitalis (medicine that helps to make the heart stronger and more efficient) and/or a beta blocker.

Dosage in special patient groups

The doctor may advise a lower dose, especially when starting treatment in certain patients such as those treated with diuretics in high doses, in patients with liver impairment, or in patients over the age of 75 years. The use of losartan is not recommended in patients with severe hepatic impairment (see section ‘Do not take Losartan Potassium Tablets'). Administration

The tablets should be swallowed with a glass of water. You should try to take your daily dose at about the same time each day. It is important that you continue to take Losartan Potassium Tablets until your doctor tells you otherwise.

If you take more Losartan Potassium Tablets than you should

If you accidentally take too many tablets, contact your doctor or go to your nearest hospital casualty department immediately. Take this leaflet and any unused tablets with you to show the doctor. Symptoms of overdose include low blood pressure (feeling dizzy or light headed, especially when standing up) and either increased or decreased heartbeat.

If you forget to take Losartan Potassium Tablets

If you accidentally miss a daily dose, just take the next dose as normal. Do not take a double dose to make up for a forgotten tablet. If you have further questions on the use of this medicine, ask your doctor or pharmacist.
