Generic Name: galsulfase (gal SUL fase)
Brand Names: Naglazyme

What is Naglazyme?

Naglazyme (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 sugars and proteins. 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.

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

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