Galsulfase

Generic name: Galsulfase
Brand names: Naglazyme
Dosage form: intravenous solution (1 mg/mL)
Drug class: Lysosomal enzymes

Usage of Galsulfase

Galsulfase contains an enzyme that occurs naturally in the body in healthy people. Some people lack this enzyme because of a genetic disorder. Galsulfase helps replace this missing enzyme in such people.

Galsulfase is used to treat some of the symptoms of a genetic condition called mucopolysaccharidosis VI (MYOO-koe-pol-ee-SAK-a-rye-DOE-sis type 6), or MPS VI, also called Maroteaux-Lamy syndrome.

MPS VI is a metabolic disorder in which the body lacks the enzyme needed to break down certain natural substances. These substances can build up in the body, causing enlarged organs, abnormal bone structure, changes in facial features, breathing problems, heart problems, vision or hearing loss, and changes in mental or physical abilities.

Galsulfase may improve walking and stair-climbing ability in people with this condition. However, this medication is not a cure for MPS VI.

Galsulfase may also be used for purposes not listed in this medication guide.

Your name may need to be listed on an MPS IV Registry while you are using galsulfase.
