What is Galsulfase?
In healthy individuals, the enzyme galsulfase is naturally present in their bodies. AGenetic disorders may make some individuals lack this enzyme; galsulfase supplements provide replacement of what's missing for these people. Galsulfase can help treat some symptoms associated with mucopolysaccharidosis VI (pronounced MYOO-koe-pol-ee-SAK-a-rye-DOE-sis type 6), more commonly referred to as Maroteaux-Lamy syndrome or MPS VI. MPS VI is a metabolic disorder where the body does not have the enzymes required to break down some natural substances. These substances can accumulate in the body and cause enlarged organs or abnormal bone structure. They may also lead to breathing problems, heart issues, vision problems, or loss of hearing. Galsulfase can improve the ability to walk and climb stairs in those with this condition. This medication is not a treatment for MPS VI. This medication guide does not list all possible uses of galsulfase.
