indication
For treatment of Fabry's disease (alpha-galactosidase A deficiency)
pharmacology
Used in the treatment of Fabry disease, an X-linked genetic disorder of glycosphingolipid metabolism. The disease is characterized by a deficiency of the lysosomal enzyme alpha-galactosidase A, which leads to progressive accumulation of glycosphingolipids, predominantly GL-3, in many body tissues. Clinical manifestations of Fabry disease include renal failure, cardiomyopathy, and cerebrovascular accidents. Fabrazyme is intended to provide an exogenous source of alpha-galactosidase A and to limit the accumulation of these glycolipids in the tissues. Studies show unconclusive evidence for the clinical efficacy of either agalasidase alfa or agalasidase beta in preventing morbidity.
mechanism of action
Alpha-galactosidase A catalyzes the hydrolysis of globotriaosylceramide (GL-3) and other a-galactyl-terminated neutral glycosphingolipids, such as galabiosylceramide and blood group B substances to ceramide dihexoside and galactose.
half life
