RT Journal Article SR Electronic A1 Lederman, Lynne T1 Concomitant DMARD Therapies Increase Adalimumab Serum Concentrations in Patients with Rheumatic Diseases JF MD Conference Express YR 2014 FD SAGE Publications VO 14 IS 17 SP 23 OP 23 DO 10.1177/155989771417015 UL http://mdc.sagepub.com/content/14/17/23.abstract AB Patients with rheumatoid arthritis (RA) who are treated with adalimumab plus methotrexate (MTX) have higher serum trough levels of adalimumab and a better clinical response to therapy than patients treated with adalimumab alone [Pouw MF et al. Ann Rheum Dis 2013]. This article discusses the effect on adalimumab serum concentrations in patients with RA or psoriatic arthritis taking concomitant MTX and concomitant disease-modifying antirheumatic drugs (DMARDs) other than MTX.
