Last updated
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Pentobarbital can lower zolpidem exposure by inducing its hepatic metabolism, which may reduce hypnotic effect. Both drugs are also sedatives, so additive central nervous system depression is possible.
What this interaction means in plain words
Pentobarbital and Zolpidem can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Barbiturate induction of CYP3A4 increases zolpidem clearance, and both agents add pharmacodynamic CNS depression.
What to do
Avoid combining sedative-hypnotics where possible; if used together, monitor for loss of hypnotic efficacy and for excess sedation or psychomotor impairment.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
