In this update on etanercept (ETN) in psoriatic arthritis (PsA) we analyze this drug's mechanism of action, clinical efficacy/effectiveness, optimal dosage, disease-modifying antirheumatic drugs (DMARD) association, radiological progression, safety, switching aspects, and pharmacoeconomy. The efficacy/effectiveness of ETN in PsA has been demonstrated in randomized placebo-controlled trials as well as in observational studies representing routine clinical practice. At 1 and 2 years, ETN inhibited radiographic disease progression, assessed by the modified total Sharp score. ETN (generally at a dosage of 50 mg/weekly) can be used either in monotherapy or in combination with DMARD such as methotrexate. A systematic search of randomized, placebo-controlled trials of ETN to treat adults with plaque psoriasis or PsA suggests that the short-term risk/benefit ratio is favorable. Longterm studies, such as observational studies, confirmed this safety profile of ETN. A variable percentage of patients withdrew anti-tumor necrosis factor-α (TNF-α) inhibitor treatment owing to inefficacy or poor tolerability. Observational studies showed that in the case of treatment failure with 1 agent, switching to the other agent may also be useful in patients with PsA because of the different molecular structures and targets of available TNF-α blockers. The clinical effect of ETN is associated with favorable pharmacoeconomic considerations. The Journal of Rheumatology
