The influence of multiple-dose oxcarbazepine on the metabolism of single-dose quetiapine. In vivo experiment in rats

Objective: Psychiatric and neurologic disorders are susceptible to polypharmacy having a higher risk of developing drug-drug interactions. Quetiapine, a frequently used atypical antipsychotic, is extensively metabolized by cytochrome P450 3A4 isoenzyme, while oxcarbazepine, an antiepileptic drug, an...

Description
Summary:Objective: Psychiatric and neurologic disorders are susceptible to polypharmacy having a higher risk of developing drug-drug interactions. Quetiapine, a frequently used atypical antipsychotic, is extensively metabolized by cytochrome P450 3A4 isoenzyme, while oxcarbazepine, an antiepileptic drug, analog of carbamazepine, is a mild-to-moderate inducer of the same isoenzyme. This study aimed to evaluate the pharmacokinetic interaction between a single dose of quetiapine and multiple doses of oxcarbazepine, as pretreatment, compared to quetiapine single-dose alone in rats.
