Mechanism of action

Etanercept is a soluble TNF receptor (p75) fused to the Fc portion of human IgG1 that acts as a TNF antagonist. By binding circulating TNF-α and TNF-β, it prevents these cytokines from engaging cell-surface TNF receptors and triggering inflammatory cascades. This reduces the pathogenic immune response in autoimmune and inflammatory conditions.
