A and B Overall Study Design (1A) - Randomized, double-blind, triple dummy, crossover study conducted in adult men and women with and without histories of alcohol dependence. The 82 randomized participants received each of 3 separate challenge tests (i.e., placebo, citalopram stimulation test [Citalopram, 2 mg/unit BMI], and the combined dexamethasone [1.5 mg]/corticotropin-releasing factor [1 μ/kg] [DEX/CRF] stimulation test) in counterbalanced order as detailed in 1.B. Outcomes from the 3-month follow-up visit assessing relapse versus continued abstinence are presented in other manuscripts.
