1 Induction of cytochrome P450 3A4 and P-glycoprotein by the isoxazolyl-penicillin antibiotic flucloxacillin. Floxacillin ATP binding cassette subfamily B member 1 Homo sapiens
2 However, incubation of human LS 180 colorectal adenocarcinoma cells with flucloxacillin led to a dose-dependent induction of MDR1 as well as of CYP3A4 mRNA, which was also confirmed in primary human hepatocytes. Floxacillin ATP binding cassette subfamily B member 1 Homo sapiens
3 These findings indicate that flucloxacillin has the potential to induce expression of both CYP3A4 as well as P-glycoprotein, most likely through activation of the nuclear hormone receptor PXR. Floxacillin ATP binding cassette subfamily B member 1 Homo sapiens
