Psoriasis and psoriatic arthritis are debilitating inflammatory immunemediated diseases which are chronic in nature and often require lifelong attention. Traditional therapies used to combat these diseases lack sufficient long-term efficacy and are associated with a number of toxicities. Failing to adequately satisfy both patients and physicians, traditional therapies have proven insufficient and have left few options. Etanercept is a tumor necrosis factor (TNF) antagonist that reduces elevated TNF levels by competitively binding to both TNF-α and TNF-β and inhibiting the proinflammatory cascade. Providing a valuable treatment option alone, etanercept can also be effectively administered in conjunction with traditional treatments. Etanercept is self administered by subcutaneous (SC) injection, making treatment less of a burden for patients by eliminating the need for frequent office visits and laboratory testing. Etanercept is approved in the US for the treatment of psoriasis, psoriatic arthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, and ankylosing spondylitis.
