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 is a recombinant human IgG1 monoclonal antibody that binds specifically to TNF-alpha, blocking its interaction with the p55 and p75 cell surface TNF receptors and inhibiting TNF-mediated inflammatory and immune responses, including modulation of adhesion molecules responsible for leukocyte migration.
