Alcohol and Pregnenolone: what the published research says

PubMed indexes 8 records that name Alcohol and Pregnenolone 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.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Alcohol and Pregnenolone. 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.

The research

8 studies naming Alcohol and Pregnenolone.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Pregnenolone effects on provoked alcohol craving, anxiety, HPA axis, and autonomic arousal in individuals with alcohol use disorder.

Psychopharmacology · 2023 · PMID 36445398

Randomized Controlled Trial

“Findings indicate that pregnenolone decreases stress- and alcohol cue-provoked craving and normalizes HPA axis and autonomic arousal in individuals with AUD, thereby supporting the need for further assessment of pregnenolone in the treatment of AUD.”

Milivojevic et al. · Authors' conclusion

Names both Alcohol and Pregnenolone in its title.

Differential hypothalamic-pituitary-adrenal activation of the neuroactive steroids pregnenolone sulfate and deoxycorticosterone in healthy controls and alcohol-dependent subjects.

Psychoneuroendocrinology · 2008 · PMID 18096321

Comparative StudyResearch Support, N.I.H., ExtramuralResearch Support, U.S. Gov't, Non-P.H.S.Human subjects

“These results indicate that plasma PREG-S and deoxycorticosterone levels are differentially regulated by HPA axis modulation in human plasma. Further, alcohol-dependent patients show a blunted PREG-S response to adrenal stimulation and a delayed deoxycorticosterone response to oCRH challenge.”

Porcu et al. · From the abstract

Names both Alcohol and Pregnenolone in its title.

Pregnenolone and pregnenolone sulfate, alone and with ethanol, in mice on the plus-maze.

Pharmacology, biochemistry, and behavior · 1994 · PMID 7972293

Comparative StudyResearch Support, U.S. Gov't, Non-P.H.S.Animal study

“However, all doses of pregnenolone tested blocked the anxiolytic effect of ethanol on the plus-maze while one dose of pregnenolone sulfate, 1.0 microgram/kg, attenuated the response to ethanol. These results support the suggestion that these neurosteroids could play a role in the initial response to stress and indicate that further work needs to be done to determine the mechanism for the interaction with ethanol.”

Melchior et al. · From the abstract

Names both Alcohol and Pregnenolone in its title.

Effects of the neuroactive steroid precursor pregnenolone on stress- and alcohol cue-provoked pain responses in individuals with alcohol use disorder.

Experimental and clinical psychopharmacology · 2026 · PMID 42258258

“PREG dose specifically reduced stress-provoked pain responses and affected concurrent pain and craving and anxiety associations, warranting further examination of PREG effects on pain and alcohol use outcomes in AUD. (PsycInfo Database Record (c) 2026 APA, all rights reserved).”

Quinlan et al. · From the abstract

Names both Alcohol and Pregnenolone in its title.

Alcohol and pregnenolone interaction on cerebral arteries through targeting of vascular smooth muscle Ca2+- and voltage-gated K(+) channels of big conductance.

Advances in drug and alcohol research · 2023 · PMID 37846408

“Moreover, cell-free recordings of BK channel activity in cerebral artery myocyte membranes showed that 10 μM pregnenolone and pregnenolone +50 mM ethanol reduced channel activity to an identical extent, suggesting that these drugs inhibit cerebrovascular BK channels via a common mechanism or mechanisms. Indeed, pregnenolone was found to disrupt allosteric coupling to Ca2+-driven gating, as previously reported for ethanol.”

North et al. · From the abstract

Names both Alcohol and Pregnenolone in its title.

Assessment of pregnenolone effects on alcohol intake and preference in male alcohol preferring (P) rats.

European journal of pharmacology · 2014 · PMID 25016089

Research Support, N.I.H., ExtramuralAnimal study

“acutely and significantly reduced alcohol intake and preference, the fact that chronic treatment did not show an effect diminishes its promise to be considered for the treatment of alcoholism. However, its profile of effects might be different in human alcoholics.”

Rezvani et al. · From the abstract

Names both Alcohol and Pregnenolone in its title.

Pregnenolone and ganaxolone reduce operant ethanol self-administration in alcohol-preferring p rats.

Alcoholism, clinical and experimental research · 2010 · PMID 20946297

Research Support, N.I.H., ExtramuralAnimal study

“These results indicate that pregnenolone dose-dependently reduces operant ethanol self-administration in P rats without locomotor impairment, suggesting that it may have potential as a novel therapeutic for reducing chronic alcohol drinking in individuals that abuse alcohol.”

Besheer et al. · Authors' conclusion

Names both Alcohol and Pregnenolone in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

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 Alcohol, Pregnenolone, 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.
