Naglazyme is used to treat patients with MPS VI disease (Mucopolysaccharidosis VI). People with MPS VI disease have either a low level, or no level, of an enzyme called N-acetylgalactosamine 4-sulfatase, 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 VI.
Naglazyme contains an artificial enzyme called galsulfase. This can replace the natural enzyme which is lacking in MPS VI disease.

<------------------------------------------------------------------------------------------------------------------------> The following information is intended for medical or healthcare professionals only:
Naglazyme should not be mixed with other medicinal products in the same infusion, except for those mentioned below.
Each vial of Naglazyme 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 Naglazyme solution be administered to patients using an infusion set equipped with a 0.2 µm in-line filter.
Any unused product or waste material is to be disposed of in accordance with local requirements.
Preparation of the Naglazyme Infusion (Use Aseptic Technique)
The number of vials to be diluted based on the individual patient's weight must be determined and removed from the refrigerator approximately 20 minutes in advance in order to allow them to reach room temperature.
Before dilution, each vial is to be inspected for particulate matter and discolouration. The clear to slightly opalescent and colourless to pale yellow solution must be free of visible particles.
A volume of the sodium chloride 9 mg/ml (0.9%) solution for infusion is to be withdrawn and discarded from a 250 ml infusion bag equal to the total volume of Naglazyme to be added. 100 ml infusion bags should be considered for patients who are susceptible to fluid volume overload and weigh less than 20 kg; in this case the infusion rate (ml/min) should be decreased so that the total duration remains no less than 4 hours. When using 100 ml bags, the volume of Naglazyme may be added directly to the infusion bag.
The volume of Naglazyme is to be slowly added to the sodium chloride 9 mg/ml (0.9%) solution for infusion.
The solution is to be mixed gently for infusion.
The solution is to be visually inspected for particulate matter prior to use. Clear and colourless solutions without visible particles should be used.
