Zolpidem Interactions

Zolpidem (Ambien) and alcohol both potentiate GABA-A receptor activity at the alpha-1 subunit, producing additive sedation, profound impairment of psychomotor performance, and significantly elevated risk of complex sleep behaviors, falls, respiratory depression, and motor vehicle crashes. Alcohol also increases zolpidem absorption and peak concentrations.

Combining the Z-drug hypnotic zolpidem with melatonin can produce additive next-day drowsiness, impaired thinking, and reduced motor coordination, with the risk most pronounced in older adults. The interaction is primarily pharmacodynamic.

Zolpidem is a Z-drug hypnotic that selectively binds the GABA-A receptor's alpha-1 subunit. Valerian's valerenic acid also modulates GABA-A receptors, producing additive sedation and a documented delay in next-morning psychomotor recovery when the two are combined.
