Oxytocin could help treat alcohol use disorder -- ScienceDaily
Administering oxytocin can decrease consumption, withdrawal symptoms, and drug-seeking behavior associated with several drugs of abuse, and shows promise as a pharmacological approach to treat drug addiction. But first, researchers need to understand how oxytocin mediates these effects in animal models. To address this question, Tunstall and colleagues tested the hypothesis that oxytocin administration could normalize the maladaptive brain changes that occur in alcohol dependence and thereby reduce alcohol drinking in an established rat model of alcohol dependence. The authors investigated oxytocin's effects on dependence-induced alcohol consumption and altered signaling of the inhibitory neurotransmitter GABA in the central nucleus of the amygdala (CeA) -- a key brain region in the network affected by alcohol dependence.
