Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adalimumab is a recombinant human IgG1 monoclonal antibody that binds specifically to tumor necrosis factor alpha (TNF-alpha) and neutralizes its biological activity by blocking its interaction with the p55 and p75 cell surface TNF receptors. It also modulates biological responses induced or regulated by TNF, including changes in adhesion molecules and apoptosis.
Infliximab is a chimeric monoclonal IgG1 antibody that binds with high affinity to tumor necrosis factor alpha (TNFα), neutralizing its pro-inflammatory cytokine activity by preventing its interaction with p55 and p75 cell surface TNF receptors.
40 mg subcutaneously every 2 weeks; may increase to 40 mg weekly if inadequate response.
5 mg/kg IV at weeks 0, 2, and 6, then every 8 weeks thereafter; for rheumatoid arthritis, may increase to 10 mg/kg every 8 weeks if needed.

Terminal elimination half-life approximately 2 weeks (12-16 days); supports every-2-week dosing in maintenance therapy.
Terminal elimination half-life is approximately 7.7 to 9.5 days (range 7-12 days). The prolonged half-life supports every-8-week dosing; may be shorter in patients with high tumor burden or immunogenicity.
Renal: 0.1-0.5% as unchanged drug in urine; biliary/fecal: 70-90% as metabolites; mostly via reticuloendothelial system degradation.
Infliximab is eliminated primarily via the reticuloendothelial system. No significant renal or biliary excretion; less than 0.1% of dose excreted unchanged in urine. Clearance is mainly through proteolytic catabolism.
