About ALDURAZYME

What is this medication? Aldurazyme is a prescription medication used to treat patients with a rare genetic condition known as Mucopolysaccharidosis I, also referred to as MPS I. This disease is caused by a deficiency in an enzyme called alpha-L-iduronidase, which the body needs to break down certain complex sugars. Because these sugars cannot be processed correctly, they build up in the body's cells and cause damage to various organs and tissues. Aldurazyme acts as an enzyme replacement therapy by providing a supplemental version of the missing enzyme to help manage these symptoms.

The medication is specifically indicated for individuals with the Hurler, Hurler-Scheie, and Scheie forms of MPS I to help improve pulmonary function and physical mobility. It is administered through an intravenous infusion, typically by a healthcare professional in a clinical setting. By reducing the accumulation of harmful substances within the body, this therapy helps to address the underlying cause of the condition and may improve the quality of life for those living with the disorder.
