What is Naglazyme (Galsulfase)?

Galsulfase is used to treat some of the symptoms of a genetic condition called Maroteaux-Lamy syndrome. Maroteaux-Lamy syndrome is also called mucopolysaccharidosis (MYOO-koe-pol-ee-SAK-a-rye-DOE-sis).
Maroteaux-Lamy syndrome 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.
Galsulfase may improve walking and stair-climbing ability in people with this condition. However, this medication is not a cure for Maroteaux-Lamy syndrome.
