Long information

What is it and how is it used?

Aldurazyme is used to treat patients with MPS I disease (Mucopolysaccharidosis I). It is given to treat the non-neurological manifestations of the disease.

People with MPS I disease have either a low level or no level of an enzyme called ?-L-iduronidase, which breaks down specific substances (glycosaminoglycans) in the body. As a result, these substances do not get broken down and processed by the body as they should. They accumulate in many tissues in the body, which causes the symptoms of MPS I.

Aldurazyme is an artificial enzyme called laronidase. This can replace the natural enzyme which is lacking in MPS I disease.

What do you have to consider before using it?

Do not use Aldurazyme
If you are allergic (hypersensitive) to any of the ingredients of Aldurazyme or if you have experienced a severe allergic reaction to laronidase.

Take special care with Aldurazyme

If you are treated with Aldurazyme, you may develop infusion-associated reactions. An infusion-associated reaction is any side effect occurring during the infusion or until the end of the infusion day (see 4 ?Possible Side Effects?). Some of these reactions may be severe. When you experience such a reaction, you should immediately contact your doctor.

If these reactions occur, the Aldurazyme infusion should be stopped immediately and appropriate treatment will be started by your doctor.
These reactions may be particularly severe if you have a pre-existing MPS I-related upper airway obstruction.
You may be given additional medication such as antihistamines and paracetamol to help prevent allergic-type reactions.

Using other medicines
Please inform your doctor if you use medicines containing chloroquine or procaine, due to a possible risk of decreasing the action of Aldurazyme.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Pregnancy and breast-feeding

There is not enough experience of the use of Aldurazyme in pregnant women. Aldurazyme should not be used during pregnancy unless clearly necessary. Ask your doctor or pharmacist for advice before taking any medicine.

It is not known whether Aldurazyme appears in breast milk. It is recommended to stop breast-feeding during treatment with Aldurazyme. Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines
The effects on the ability to drive and to use machines have not been studied.

<-------------------------------------------------------------------------------------------------------------------------- The following information is intended for medical or healthcare professionals only:

Each vial of Aldurazyme is intended for single use only. The concentrate for solution for infusion has to be diluted with sodium chloride 9 mg/ml (0.9%) solution for infusion using aseptic technique. It is recommended that the diluted Aldurazyme solution be administered to patients using an infusion set equipped with an 0.2 µm in-line filter.

From a microbiological safety point of view, the product should be used immediately. If not used immediately, in-use storage should not be longer than 24 hours at 2°C - 8°C provided that dilution has taken place under controlled and validated aseptic conditions.

Aldurazyme should not be mixed with other medicinal products in the same infusion.

Preparation of the Aldurazyme Infusion (Use Aseptic Technique)

Determine the number of vials to be diluted based on the individual patient's weight. Remove the required vials from the refrigerator approximately 20 minutes in advance in order to allow them to reach room temperature (below 30-C).
Before dilution, visually inspect each vial for particulate matter and discoloration. The clear to slightly opalescent and colourless to pale yellow solution should be free of visible particles. Do not use vials exhibiting particles or discoloration.
Determine the total volume of infusion based on the individual patient's weight, either 100 ml (if bodyweight is less or equal than 20 kg) or 250 ml (if bodyweight is more than 20 kg) of 0.9% sodium chloride intravenous solution.
Withdraw and discard a volume of sodium chloride 9 mg/ml (0.9%) solution for infusion from the infusion bag equal to the total volume of Aldurazyme to be added.
Withdraw the required volume from the Aldurazyme vials and combine the withdrawn volumes. Add the combined volumes of Aldurazyme to the sodium chloride 9 mg/ml (0.9%) solution for infusion.
Mix the solution for infusion gently.
Prior to use visually inspect the solution for particulate matter. Only clear and colourless solutions without visible particles should be used.

Any unused product or waste material should be disposed of in accordance with local requirements.
