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.
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.
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.
40 mg subcutaneously every 2 weeks; may increase to 40 mg weekly if inadequate response.

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 approximately 2 weeks (12-16 days); supports every-2-week dosing in maintenance therapy.
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.
Renal: 0.1-0.5% as unchanged drug in urine; biliary/fecal: 70-90% as metabolites; mostly via reticuloendothelial system degradation.
