Aldurazyme

Generic Name: laronidase (lah RAH nih daze)
Brand Names: Aldurazyme

What is Aldurazyme?

Aldurazyme (laronidase) is used to treat some of the symptoms of a genetic condition called Hurler syndrome, also called mucopolysaccharidosis, or MPS I. Forms of MPS I include Hurler syndrome, Hurler-Scheie syndrome, and Scheie syndrome.

MPS I 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.

Aldurazyme may improve breathing and walking ability in people with this condition. However, this medication is not a cure for MPS I.

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