Advances in the neurobiology of alcohol dependence have highlighted an association between hyperactivation of stress systems in the CNS and drinking relapse risk during protracted withdrawal. A pharmacological strategy that facilitates homeostasis in stress systems dysregulated by drinking cessation may offer new treatment options for AUD. Screening such drug candidates in a validated human laboratory model of protracted withdrawal may increase the likelihood of selecting drugs that show efficacy in clinical trials. Data in support of the predictive validity of a human lab model of protracted withdrawal will be presented from a human lab study and an independent clinical trial of gabapentin, and a human lab study with post-treatment drinking data of a glucocorticoid antagonist (mifepristone) in volunteers with alcohol dependence. Data from these studies provide clinical validation of hyperactivation of central stress systems as a pharmacological treatment target, and support the predictive validity of a human lab model of risk factors for drinking relapse during protracted withdrawal in alcohol dependence.
