TLDR GABAergic steroid precursors reduce ethanol withdrawal symptoms in certain mice.
The study examined the impact of neuroactive steroids (NAS) on ethanol withdrawal symptoms in mice that had undergone adrenalectomy and gonadectomy (ADX/GDX). It was observed that the removal of adrenal and gonadal sources of NAS heightened withdrawal severity, indicated by handling-induced convulsions (HICs) after ethanol exposure. Administering progesterone (PROG) and deoxycorticosterone (DOC) to ADX/GDX mice restored their withdrawal profile to that of intact animals, an effect that was inhibited by finasteride (FIN), a 5α-reductase inhibitor. These results suggested that the absence of GABAergic NAS increased withdrawal severity, underscoring the role of endogenous NAS in managing ethanol withdrawal.
