Patients with psoriatic arthritis who switched to a second anti-tumor necrosis factor inhibitor drug had lower drug-survival rates at three years compared with those who remained on their first medication, researchers in Norway found. Switchers also showed much poorer responses in factors such as Disease Activity Score-28 remission and American College of Rheumatology-50 response than non-switchers. The findings were published in the journal Annals of the Rheumatic Diseases.
