Official title
Defining Factors Responsible for Temporal Changes in CYP3A4-Mediated Drug Metabolism During Pregnancy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The objectives of this application are to provide mechanistic understanding of altered drug metabolism by hepatic cytochrome CYP3A4 and to translate the findings to human pregnancy. A drug metabolized by CYP3A4, Quetiapine, will be the drug of choice mechanism to understand the enzyme's induction. Pregnant women currently on Quetiapine will be recruited. If the women enroll, the women will participate in four pharmacokinetic (PK) studies (one per trimester, and one postpartum).
