How does this medication work? What will it do for me?
Idursulfase belongs to the class of medications called enzyme replacement therapies (ERT). It is used to help improve walking capacity for people with Hunter syndrome, or mucopolysaccharidosis II (MPS II).
Hunter syndrome is a genetic condition where the body does not produce enough of the enzyme iduronate-2-sulfatase. This causes the buildup of substances called glycosaminoglycans (GAG) in cells and tissues. Idursulfase works by increasing the amounts of enzyme, which then helps to remove GAG and reduce the accumulation of GAG in the body.
