Pharmacology
Dupilumab is a human monoclonal IgG4 antibody that inhibits IL-4 and IL-13 signaling by binding to the IL-4Ra subunit shared by the IL-4 and IL-13 receptor complexes, blocking cytokine-induced inflammatory responses including release of proinflammatory cytokines, chemokines, nitric oxide, and IgE.
Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
