Erythromycin 77-89 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 93-99 8894516-10 1996 These studies in hepatic microsomes demonstrate that fluoroquinolones can decrease CYP3A- and CYP1A-mediated biotransformation by competitive inhibition and that they have the potential to cause drug interactions with agents metabolized by these enzymes. Fluoroquinolones 53-69 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 83-88
