Effect of omeprazole on the pharmacokinetics of sustained-release carbamazepine in healthy male volunteers

Methods Find Exp Clin Pharmacol. Jan-Feb 2001;23(1):37-9. doi: 10.1358/mf.2001.23.1.619178.


The present study shows the effect of omeprazole administration on the pharmacokinetics of a sustained-release preparation of carbamazepine in healthy male volunteers. Multiple dose administration of omeprazole increased the Cmax, AUC0-infinity and elimination half life (t1/2e) of carbamazepine. The results suggest that drug monitoring should be carried out when carbamazepine is coadministered with omeprazole.
