Iguratimod is an anti-inflammatory small molecule drug used for the treatment of rheumatoid arthritis, together with methotrexate in Japan and China.[1] As of 2015 the biological target was not known, but it prevents NF-κB activation and subsequently selectively inhibits COX-2 and several inflammatory cytokines.[1]

Adverse effects include elevated transaminases, nausea, vomiting, stomach pain; rashes, and itchiness.[1]

It is a derivative of 7-methanesulfonylamino-6-phenoxychromones and is a chromone with two amide groups; it was first published in 2000.[1][2] It was submitted for regulatory approval in Japan in 2003; the application was withdrawn in 2009, and it was resubmitted with additional data in 2011 and approved for marketing in Japan in 2012.[1] Eisai and Toyama Chemical market it in Japan.[3] Approval was obtained in China in 2011 by Simcere, independently of the Japanese originators.[1][4]

During discovery and development it was called T-614 and it is marketed under the names Careram and Kolbet.[5]
