Medical Uses
Aldurazyme (laronidase) is a hydrolytic lysosomal glycosaminoglycan (GAG)-specific enzyme used for the treatment and management of adult and pediatric patients with Hurler and Hurler-Scheie forms of Mucopolysaccharidosis I (MPS I). The medicine is also used for patients with the Scheie form of MPS I with moderate to severe signs and symptoms.
Limitations of Use: The risks and benefits of treating patients with the mild Scheie form remain uncertain. Additionally, the impact of this medicine on central nervous system symptoms associated with the disorder has not been thoroughly studied.
Recommended Dosage: The recommended dosage of Aldurazyme injection is 0.58 mg/kg (body weight) administered via weekly intravenous (IV) infusion. Dilute with 0.9% Sodium Chloride to 50 mL for those weighing 2 kg to 4 kg, 100 mL for 4 kg to 20 kg, and 250 mL for over 20 kg. For those with cardiac or respiratory complications weighing up to 30 kg, a 100 mL dilution with a reduced infusion rate may be considered. Start infusion at 10 mcg/kg/hr, gradually increasing every 15 minutes to a maximum of 200 mcg/kg/hr, maintained for 2 to 3 hours. Resume missed doses promptly. Maintain the weekly schedule. Never double a dose to compensate for missed treatment.
