Pharmacology
IL-6 receptor antagonist; sarilumab is a human recombinant IgG1 monoclonal antibody that binds to both soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R), inhibiting IL-6-mediated pro-inflammatory signaling involved in T-cell activation, acute phase protein synthesis, and joint inflammation.
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.
