Possible Interaction: Ethanol and Pregnanolone



Research Papers that Mention the Interaction

When administered with ethanol , 1 and 3.2 mg/kg of pregnanolone enhanced the discriminative stimulus effects of small ethanol doses more in saline-treated adolescents than in ethanol-treated adolescents.

Acute ethanol administration induces a dose- and time-dependent increase in brain concentration of the neuroactive steroid allopregnanolone.
Brain Research Reviews  •  2003  |  View Paper
Chronic exposure to ethanol resulted in a decrease in muscimol-stimulated 36Cl- flux and a decrease in modulation of that flux by ethanol, flunitrazepam, methyl-6,7-4-dimethoxy-4-ethyl-beta-carboline-3-carboxylate and pregnanolone without any change in the modulation by pentobarbital or zinc.

Finally, under the multiple schedule, noncontingent injections of ethanol (0.32-1.8 g/kg), DHEA (10-100 mg/kg), and pregnanolone (1.8-32 mg/kg) dose-dependently decreased food- and ethanol-maintained responding and the dose of ethanol presented.
Further, we have shown that two neurosteroids, dehydroepiandrosterone (DHEA) and pregnanolone , can readily decrease ethanol self-administration in males.

BACKGROUND Ethanol (EtOH) administration increases brain allopregnanolone levels in rats, and this increase contributes to sensitivity to EtOH's behavioral effects.

LTP block was enhanced at lower ethanol concentrations in the presence of (3α5α)‐3‐hydroxypregnan‐20‐one , a GABAAR‐potentiating neurosteroid, suggesting that neurosteroids may be important contributors to the effects of ethanol on LTP.

The ability of epiallopregnanolone to antagonize the discriminative stimulus or rate-altering effects of ethanol or alphaxalone was also assessed.

Consumption of ethanol significantly increased brain allopregnanolone levels in male but not female mice, compared with animals drinking water, but did not alter plasma corticosterone levels.

Similarly, the GABA(A) receptor positive modulators, pregnanolone , chlordiazepoxide, and pentobarbital exhibited TD(50)s of 20.8, 4.6, and 29.7 mg/kg, respectively, when administered alone and 2.7, 0.3, and 11.4 mg/kg, respectively, when administered in the presence of ethanol.

PE, PS, DHEA, DHEAS, and PA were also capable of blocking the memory-impairing effect of 0.5 g/kg ethanol.
