GABA and Lorazepam: what the published research says
PubMed indexes 3 records that name GABA and Lorazepam together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to GABA and Lorazepam. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
3 studies naming GABA and Lorazepam.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
Journal of the Academy of Consultation-Liaison Psychiatry · 2025 · PMID 39522949
Systematic ReviewHuman subjects
“An 80% positive response rate for zolpidem in lysing catatonia is encouraging but may be an overestimate due to reporting bias of case-level data. Results may be explained by zolpidem's selectivity for the α1 subunit of the GABAA receptor. Thus, zolpidem may be an underutilized catatonia treatment and prove useful in situations when benzodiazepines fail or when electroconvulsive therapy access is limited.”
Names GABA and Lorazepam together in an interaction, co-administration, or pharmacokinetic context.
“Baclofen significantly reduced SIHI and LIHI while lorazepam had no effect. These findings advance our understanding of the pharmacological basis of transcallosal inhibition in humans.”

“These results support similar though not identical mechanisms for the effects of alcohol and benzodiazepines on brain glucose metabolism. The fact that lorazepam, but not alcohol, reduced thalamic metabolism, an effect associated with sleepiness, could explain the higher sedative effects of lorazepam than of alcohol.”

Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers GABA, Lorazepam, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
