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.
TNF-alpha antagonist; infliximab-abda is a chimeric IgG1kappa monoclonal antibody that neutralizes TNF-alpha by binding with high affinity to soluble and transmembrane forms of TNF-alpha, inhibiting receptor binding and suppressing downstream pro-inflammatory activity.
