atc code l04 atc code l04 atc code l04 immunosuppressants is a therapeutic subgroup of the anatomical therapeutic chemical classification system, a system of alphanumeric codes developed by the world health organization (who) for the classification of drugs and other medical products. subgroup l04 is part of the anatomical group l antineoplastic and immunomodulating agents. atc codes l antineoplastic and immunomodulating agents l01 antineoplastic agents l02 endocrine therapy l03 immunostimulants l04 immunosuppressants a b c d g h qi j l m n p r s v codes for veterinary use (atcvet codes) can be created by placing the letter q in front of the human atc code: for example, ql04. national issues of the atc classification may include additional codes not present in this list, which follows the who version. l04a immunosuppressants l04aa selective immunosuppressants l04aa02 muromonab-cd3 l04aa03 antilymphocyte immunoglobulin (horse) l04aa04 antithymocyte immunoglobulin (rabbit) l04aa06 mycophenolic acid l04aa10 sirolimus l04aa13 leflunomide l04aa15 alefacept l04aa18 everolimus l04aa19 gusperimus l04aa21 efalizumab l04aa22 abetimus l04aa23 natalizumab l04aa24 abatacept l04aa25 eculizumab l04aa26 belimumab l04aa27 fingolimod l04aa28 belatacept l04aa29 tofacitinib l04aa31 teriflunomide l04aa32 apremilast l04aa33 vedolizumab l04aa34 alemtuzumab l04aa35 begelomab l04aa36 ocrelizumab l04aa37 baricitinib l04aa38 ozanimod l04aa39 emapalumab l04aa40 cladribine l04aa41 imlifidase l04aa42 siponimod l04aa43 ravulizumab l04aa44 upadacitinib l04aa45 filgotinib l04aa46 itacitinib l04aa47 inebilizumab l04aa48 belumosudil l04aa49 peficitinib l04aa50 ponesimod l04aa51 anifrolumab l04aa52 ofatumumab l04aa53 teprotumumab l04aa54 pegcetacoplan l04aa55 sutimlimab l04aa56 deucravacitinib l04aa57 ublituximab l04aa58 efgartigimod alfa l04aa59 avacopan l04ab tumor necrosis factor alpha (tnf-α) inhibitors l04ab01 etanercept l04ab02 infliximab l04ab03 afelimomab l04ab04 adalimumab l04ab05 certolizumab pegol l04ab06 golimumab l04ab07 opinercept l04ac interleukin inhibitors l04ac01 daclizumab l04ac02 basiliximab l04ac03 anakinra l04ac04 rilonacept l04ac05 ustekinumab l04ac07 tocilizumab l04ac08 canakinumab l04ac09 briakinumab l04ac10 secukinumab l04ac11 siltuximab l04ac12 brodalumab l04ac13 ixekizumab l04ac14 sarilumab l04ac15 sirukumab l04ac16 guselkumab l04ac17 tildrakizumab l04ac18 risankizumab l04ac19 satralizumab l04ac20 netakimab l04ac21 bimekizumab l04ac22 spesolimab l04ac23 olokizumab l04ad calcineurin inhibitors l04ad01 ciclosporin l04ad02 tacrolimus l04ad03 voclosporin l04ax other immunosuppressants l04ax01 azathioprine l04ax02 thalidomide l04ax03 methotrexate l04ax04 lenalidomide l04ax05 pirfenidone l04ax06 pomalidomide l04ax07 dimethyl fumarate l04ax08 darvadstrocel l04ax09 diroximel fumarate
