Computational drug-drug interaction prediction mediated by CYP450 isoforms of Ilaprazole coadministered with clopidogrel.

Abstract

Ilaprazole due to its pharmacokinetic variability does not affect the clopidogrel efficacy during concomitant use. Methodology: Prediction of DDI for Clopidogrel and PPIs performed using (DDI-Pred) Way2Drug software. The probabilities ΔP, which estimate the potential DDIs resulting from interaction with CYP450 isoenzymes. Results: Positive ΔP-values for CYP2C19 (0.955) indicate that it is involved in the drug interaction of Ilaprazole and Clopidogrel. Discussion: Pantoprazole and Ilaprazole were found to have a low probability of CYP2C19 inhibition Conclusion: Compared with other PPIs, Pantoprazole and Ilaprazole were found to have a low probability of CYP2C19 inhibition; Since Ilaprazole has pharmacokinetic variability, further in vivo and in vitro studies are required on the ilaprazole and clopidogrel combination to assess the effect of drug-drug interaction.
