Pharmacology
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.
TSLP blocker; tezepelumab-ekko is a human monoclonal antibody (IgG2lambda) that binds human thymic stromal lymphopoietin (TSLP) and blocks its interaction with the heterodimeric TSLP receptor, thereby reducing inflammatory biomarkers including blood eosinophils, IgE, FeNO, IL-5, and IL-13.
