Laronidase is used to treat a certain rare genetic problem (mucopolysaccharidosis-MPS I). It works by replacing a certain natural substance (lysosomal enzyme) that is missing in people with this genetic problem. This medication improves lung function and how far you can walk. Laronidase is not a cure and treatment must be continued for life.
