1 RESULTS: Cytochrome P4503A (CYP3A) activity was reduced in all subjects by a mean level of 26% following clarithromycin treatment. Clarithromycin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 RESULTS: Cytochrome P4503A (CYP3A) activity was reduced in all subjects by a mean level of 26% following clarithromycin treatment. Clarithromycin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
3 CONCLUSIONS: As clarithromycin was shown to inhibit CYP3A activity in all subjects tested, we recommend that a high degree of caution be exercised when clarithromycin is administered to patients receiving cyclosporine therapy or other drugs known to be eliminated by CYP3A-mediated metabolism. Clarithromycin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
