Tolura 80 mg tablets

 

What is it and how is it used?

Tolura belongs to a class of medicines known as angiotensin II receptor antagonists. Angiotensin II is a substance produced in your body which causes your blood vessels to narrow, thus increasing your blood pressure. Tolura blocks the effect of angiotensin II so that the blood vessels relax, and your blood pressure is lowered.

Tolura is used to treat essential hypertension (high blood pressure). ‘Essential’ means that the high blood pressure is not caused by any other condition.

High blood pressure, if not treated, can damage blood vessels in several organs, which could lead sometimes to heart attack, heart or kidney failure, stroke, or blindness. There are usually no symptoms of high blood pressure before damage occurs. Thus it is important to regularly measure blood pressure to verify if it is within the normal range.

What do you have to consider before using it?

Do not take Tolura

  • if you are allergic (hypersensitive) to telmisartan or any other ingredients included in Tolura tablets (see section Further information for a list of other ingredients).
  • if you are more than 3 months pregnant. (It is also better to avoid Tolura in early pregnancy – see pregnancy section.)
  • if you have severe liver problems such as cholestasis or biliary obstruction (problems with the drainage of the bile from the liver and gall bladder) or any other severe liver disease.

If any of the above applies to you, tell your doctor or pharmacist before taking Tolura.

Take special care with Tolura

Please tell your doctor if you are suffering or have ever suffered from any of the following conditions or illnesses:

  • Kidney disease or kidney transplant.
  • Renal artery stenosis (narrowing of the blood vessels to one or both kidneys).
  • Liver disease.
  • Heart trouble.
  • Raised aldosterone levels (water and salt retention in the body along with imbalance of various blood minerals).
  • Low blood pressure (hypotension), likely to occur if you are dehydrated (excessive loss of body water) or have salt deficiency due to diuretic therapy ('water tablets'), low-salt diet, diarrhoea, or vomiting.
  • Elevated potassium levels in your blood.
  • Diabetes.

You must tell your doctor if you think you are (or might become) pregnant. Tolura 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).

In case of surgery or anaesthesia, you should tell your doctor that you are taking Tolura.

The use of Tolura in children and adolescents up to the age of 18 years is not recommended.

As with all other angiotensin II receptor antagonists, Tolura may be less effective in lowering the blood pressure in black patients.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. Your doctor may need to change the dose of these other medicines or take other precautions. In some cases you may have to stop taking one of the medicines. This applies especially to the medicines listed below taken at the same time with Tolura:

  • Lithium containing medicines to treat some types of depression.
  • Medicines that may increase blood potassium levels such as salt substitutes containing potassium, potassium-sparing diuretics (certain 'water tablets'), ACE inhibitors, angiotensin II receptor antagonists, NSAIDs (non steroidal anti-inflammatory medicines, e.g. aspirin or ibuprofen), heparin, immunosuppressives (e.g. cyclosporin or tacrolimus), and the antibiotic trimethoprim.
  • Diuretics ('water tablets'), especially if taken in high doses together with Tolura, may lead to excessive loss of body water and low blood pressure (hypotension).

As with other blood pressure lowering medicines, the effect of Tolura may be reduced when you take NSAIDs (non steroidal anti-inflammatory medicines, e.g. aspirin or ibuprofen) or corticosteroids.

Tolura may increase the blood pressure lowering effect of other medicines used to treat high blood pressure.

Taking Tolura with food and drink

You can take Tolura with or without food.

Pregnancy and breast-feeding

Pregnancy
You must tell your doctor if you think you are (or might become) pregnant. Your doctor will normally advise you to stop taking Tolura before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Tolura. Tolura 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.

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

Driving and using machines

No information is available on the effect of Tolura on the ability to drive or operate machinery. Some people feel dizzy or tired when they are treated for high blood pressure. If you feel dizzy or tired, do not drive or operate machinery.

Important information about some of the ingredients of Tolura

Tolura contains lactose and sorbitol (E420).
If you are intolerant to some sugars, consult your doctor before taking Tolura.

How is it used?

Always take Tolura exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

The usual dose of Tolura is one tablet a day. Try to take the tablet at the same time each day. You can take Tolura with or without food. The tablets should be swallowed with some water or other non-alcoholic drink. It is important that you take Tolura every day until your doctor tells you otherwise. If you have the impression that the effect of Tolura is too strong or too weak, talk to your doctor or pharmacist.

The usual dose of Tolura for most patients is one 40 mg tablet once a day to control blood pressure over the 24 hour period. However, sometimes your doctor may recommend a lower dose of 20 mg or a higher dose of 80 mg. Tolura may also be used in combination with diuretics ('water tablets') such as hydrochlorothiazide which has been shown to have an additive blood pressure lowering effect with Tolura.

If your liver is not working properly, the usual dose should not exceed 40 mg once daily.

If you take more Tolura than you should

If you accidentally take too many tablets, contact your doctor, pharmacist, or your nearest hospital emergency department immediately.

If you forget to take Tolura

If you forget to take a dose, do not worry. Take it as soon as you remember then carry on as before. If you do not take your tablet on one day, take your normal dose on the next day. Do not take a double dose to make up for forgotten individual doses.

If you have any further questions on the use of this product, ask your doctor or pharmacist.

If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your doctor or pharmacist.

How should it be stored?

Keep out of the reach and sight of children.

Do not use Tolura after the expiry date which is stated on the carton and blister after “EXP”. The expiry date refers to the last day of that month.

Store in the original package in order to protect from light.

Medicines should not be disposed of via wastewater or household waste. Ask your pharmacist how to dispose of medicines no longer required. These measures will help to protect the environment.

What is it?

Tolura is a medicine that contains the active substance telmisartan. It is available as white tablets (round: 20 mg; oval: 40 mg; capsule-shaped: 80 mg).

Tolura is a ‘generic medicine’. This means that Tolura is similar to a ‘reference medicine’ already authorised in the European Union (EU) called Micardis. For more information on generic medicines, see the question-and-answer document here.

What is it used for?

Tolura is used to treat essential hypertension (high blood pressure) in adults. ‘Essential’ means that the hypertension has no obvious cause.

The medicine can only be obtained with a prescription.

How is it used?

The recommended dose of Tolura is 40 mg once a day, but some patients may benefit from using a 20-mg dose. If the target blood pressure is not reached, the dose can be increased to 80 mg, or another medicine for hypertension can be added, such as hydrochlorothiazide.

How does it work?

The active substance in Tolura, telmisartan, is an ‘angiotensin II receptor antagonist’, which means that it blocks the action of a hormone in the body called angiotensin II. Angiotensin II is a powerful vasoconstrictor (a substance that narrows blood vessels). By blocking the receptors to which angiotensin II normally attaches, telmisartan stops the hormone having an effect, allowing the blood vessels to widen. This allows the blood pressure to drop, reducing the risks associated with high blood pressure, such as having a heart attack or stroke.

How has it been studied?

Because Tolura is a generic medicine, studies in patients have been limited to tests to determine that it is bioequivalent to the reference medicine, Micardis. Two medicines are bioequivalent when they produce the same levels of the active substance in the body.

What benefits has it shown during the studies?

Because Tolura is a generic medicine and is bioequivalent to the reference medicine, its benefit and risk are taken as being the same as the reference medicine’s.

What is the risk associated?

Because Tolura is a generic medicine and is bioequivalent to the reference medicine, its benefit and risk are taken as being the same as the reference medicine’s.

Why has it been approved?

The CHMP concluded that, in accordance with EU requirements, Tolura has been shown to have comparable quality and to be bioequivalent to Micardis. Therefore, the CHMP’s view was that, as for Micardis, the benefit outweighs the identified risk. The Committee recommended that Tolura be given marketing authorisation.

Further information

The European Commission granted a marketing authorisation valid throughout the EU for Tolura to Krka, d.d., Novo mesto on 4 June 2010. The marketing authorisation is valid for five years, after which it can be renewed.
