Agalsidase beta belongs to the group of medications known as enzyme replacement therapy. It is used as enzyme replacement therapy for people with Fabry disease, which is a genetic disorder where the levels of alpha-galactosidase (an enzyme that breaks down fats) is low or absent. With Fabry disease, globotriaosylceramide (or GL-3; a fat substance) is not removed from cells in the body and starts to accumulate in the walls of blood vessels and organs. By reducing GL-3 levels in the body, agalsidase beta slows the rate of progression of Fabry disease in the kidney, heart, and brain.
