Mechanism of action
Etanercept consists of the extracellular ligand-binding portion of the human TNF receptor II fused to the Fc region of human IgG1. It acts as a soluble TNF receptor that competitively binds TNF-alpha and TNF-beta, preventing their interaction with cell-surface TNF receptors and thereby suppressing the inflammatory cascade. This mechanism reduces the production of inflammatory mediators and decreases immune cell activation.
