Interaction Effect
Reduced zolpidem exposure
Interaction Summary
Concomitant use of zolpidem and a CYP3A4 inducer may result in decreased zolpidem exposure and is not recommended. In a drug-interaction study in female subjects, coadministration of rifAMPin and zolpidem significantly reduced the exposure of zolpidem and its pharmacodynamic effects.
Severity
Major
Onset
Unspecified
Evidence
Probable
How To Manage Interaction
Concomitant use of zolpidem (a CYP3A4 substrate) and a CYP3A4 inducer may result in decreased zolpidem exposure and is not recommended.
Mechanism Of Interaction
Induction of CYP3A4-mediated zolpidem metabolism
Literature Reports
A) In a drug-interaction study in female subjects, coadministration of a single zolpidem tartrate 10 mg dose and rifAMPin 600 mg at steady-state resulted in significant reductions in the AUC (-73%), Cmax (-58%), and t(1/2) (-36%) of zolpidem and significant reductions in its pharmacodynamic effects .
Zolpidem Overview
-
Zolpidem is used to treat insomnia (difficulty falling asleep or staying asleep). Zolpidem belongs to a class of medications called sedative-hypnotics. It works by slowing activity in the brain to allow sleep.
Oxcarbazepine Overview
