Pharmacology

Adalimumab-afzb is a recombinant human IgG1 monoclonal antibody TNF-alpha blocker that binds specifically to TNF-alpha and blocks its interaction with the p55 and p75 cell surface TNF receptors, reducing inflammation and modulating TNF-induced biological responses including leukocyte migration.

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.
