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-α) and blocks its interaction with p55 and p75 cell surface TNF receptors. It also modulates biological responses that are induced or regulated by TNF-α, including expression of adhesion molecules, chemotaxis, and pro-inflammatory cytokine release.
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.
Subcutaneous injection: 40 mg every other week; for patients with Crohn disease, an initial dose of 160 mg (given as four 40 mg injections in one day or two 40 mg injections per day for two consecutive days) followed by 80 mg at week 2 and 40 mg every other week starting at week 4.
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 is approximately 14 days (range 10-20 days) in patients receiving 40 mg every other week. This long half-life supports biweekly dosing.
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.
Adalimumab (AMJEVITA) is eliminated primarily via intracellular catabolism, with negligible renal or biliary excretion. No intact drug is excreted in urine. The Fe receptor-mediated recycling contributes to long half-life.
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.
