Summary

Etanercept is an anti-inflammatory drug used to treat rheumatoid arthritis and other inflammatory conditions. Etanercept works by inhibiting TNF signaling, by acting as a decoy receptor for TNF. The resulting decrease in TNF signaling has potent anti-inflammatory effects. Clinically, etanercept is used to treat autoimmune diseases like rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis. Since etanercept is immunosuppressive, it comes with a risk of reactivating latent TB.
