1 Mibefradil but not isradipine substantially elevates the plasma concentrations of the CYP3A4 substrate triazolam. Mibefradil cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 BACKGROUND: The calcium channel blockers mibefradil and isradipine inhibit CYP3A4 in vitro. Mibefradil cytochrome P450 family 3 subfamily A member 4 Homo sapiens
3 CONCLUSION: Mibefradil but not isradipine markedly increases the plasma concentrations of triazolam and thereby enhances and prolongs its pharmacodynamic effects, consistent with potent inhibition of CYP3A4. Mibefradil cytochrome P450 family 3 subfamily A member 4 Homo sapiens
