Interaktioner i forbindelse med disse metaboliserende enzymer in vivo anses derfor for at være usandsynlige.
Based on in vitro data, azacitidine metabolism does not appear to be mediated by cytochrome P450 isoenzymes (CYPs), UDP-glucuronosyltransferases (UGTs), sulfotransferases (SULTs), and glutathione transferases (GSTs); interactions related to these metabolizing enzymes in vivo are therefore considered unlikely.
