Resumen:
Taurine is a non-essential ß sulfonated amino acid involved in a plethora of biological functions in the mammalian central nervous system. Taurine is easily accessible in energy drinks for human consumption. Previous preclinical and clinical reports suggest that acute systemic administration of taurine could inhibit some of the behavioral and metabolic effects of alcohol use disorder. Overall, both in rodent and human studies, acute taurine administration reduced voluntary alcohol intake. This study aimed to assess the pharmacological effects of taurine (intracerebroventricular; i.c.v.) on ethanol intake/preference of rats either control (i.e., alcohol naïve) or forced ethanol intake (since juvenile age with a chronic intermittent access model). In addition, to explore anxiety-like behavior (through defensive burying behavior test) as pharmacological control of taurine. We found that acute (i.c.v.) taurine reduced alcohol consumption, i.e., taurine significantly decreased both alcohol intake and preference in adult male Wistar rats. Moreover, taurine elicits an anxiolytic-like effect in all administered groups independently of previous alcohol exposure. © 2024 Elsevier B.V.
