1 The objectives of this study were to characterize and compare the reversible inhibition and time-dependent inactivation of cytochromes P450 3A4 and 3A5 (CYP3A4 and CYP3A5) by erythromycin, diltiazem, and nicardipine. Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
2 In conclusion, erythromycin, diltiazem, and nicardipine were weaker inhibitors of CYP3A5 and inactivated the enzyme at a slower rate than their respective effects on CYP3A4. Diltiazem cytochrome P450 family 3 subfamily A member 5 Homo sapiens
