Pharmacology
ASCENIV is an intravenous immunoglobulin replacement therapy that provides a broad spectrum of neutralizing IgG antibodies against bacterial and viral pathogens and their toxins; IgG antibodies act as opsonins to increase phagocytosis and elimination of pathogens from the circulation.
GAMUNEX-C supplies a broad spectrum of opsonic and neutralizing IgG antibodies against bacterial, viral, parasitic, and mycoplasmal agents and their toxins; the precise mechanisms of action in ITP and CIDP have not been fully elucidated.
