Pharmacology
IL-1 receptor antagonist; anakinra is a recombinant human IL-1Ra that competitively inhibits IL-1alpha and IL-1beta binding to the interleukin-1 type I receptor (IL-1RI), blocking downstream inflammatory and immunological responses including cartilage degradation and bone resorption.
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.
