Pharmacology

Rituximab is a chimeric murine/human IgG1 kappa monoclonal antibody that binds the CD20 antigen on pre-B and mature B-lymphocytes, mediating B-cell lysis via complement dependent cytotoxicity (CDC) and antibody dependent cell mediated cytotoxicity (ADCC).

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.
