atc code b03 atc code b03 atc code b03 antianemic preparations 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 b03 is part of the anatomical group b blood and blood forming organs. atc codes b blood and blood forming organs b01 antithrombotic agents b02 antihemorrhagics b03 antianemic preparations b05 blood substitutes and perfusion solutions b06 other hematological agents 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, qb03. atcvet codes without corresponding human atc codes are cited with the leading q in the following list.national issues of the atc classification may include additional codes not present in this list, which follows the who version. b03a iron preparations b03aa iron bivalent, oral preparations b03aa01 ferrous glycine sulfate b03aa02 ferrous fumarate b03aa03 ferrous gluconate b03aa04 ferrous carbonate b03aa05 ferrous chloride b03aa06 ferrous succinate b03aa07 ferrous sulfate b03aa08 ferrous tartrate b03aa09 ferrous aspartate b03aa10 ferrous ascorbate b03aa11 ferrous iodine b03aa12 ferrous sodium citrate b03ab iron trivalent, oral preparations b03ab01 ferric sodium citrate b03ab02 saccharated iron oxide b03ab03 sodium feredetate b03ab04 ferric hydroxide b03ab05 ferric oxide polymaltose complexes b03ab07 chondroitin sulfate-iron complex b03ab08 ferric acetyl transferrin b03ab09 ferric proteinsuccinylate b03ab10 ferric maltol qb03ab90 iron dextran complexes b03ad iron in combination with folic acid b03ad01 ferrous amino acid complex and folic acid b03ad02 ferrous fumarate and folic acid b03ad03 ferrous sulfate and folic acid b03ad04 ferric oxide polymaltose complexes and folic acid b03ad05 ferrous gluconate and folic acid b03ae iron in other combinations b03ae01 iron, vitamin b12 and folic acid b03ae02 iron, multivitamins and folic acid b03ae03 iron and multivitamins b03ae04 iron, multivitamins and minerals b03ae10 various combinations b03b vitamin b12 and folic acid b03ba vitamin b12 (cyanocobalamin and analogues) b03ba01 cyanocobalamin b03ba02 cyanocobalamin tannin complex b03ba03 hydroxocobalamin b03ba04 cobamamide b03ba05 mecobalamin b03ba51 cyanocobalamin, combinations b03ba53 hydroxocobalamin, combinations b03bb folic acid and derivatives b03bb01 folic acid b03bb51 folic acid, combinations b03x other antianemic preparations b03xa other antianemic preparations b03xa01 erythropoietin b03xa02 darbepoetin alfa b03xa03 methoxy polyethylene glycol-epoetin beta b03xa04 peginesatide b03xa05 roxadustat b03xa06 luspatercept b03xa07 daprodustat b03xa08 vadadustat
