About this trial
This is a randomized controlled trial (RCT), within-subject, crossover, double-blind, placebo-controlled in non-treatment-seeking individuals with Alcohol Use Disorder (AUD) (N=40, 50% female) randomized to IN insulin or placebo. In a bar laboratory setting, randomized participants will receive a single dose of IN insulin (80IU) or an IN matched placebo (0.9% Saline). Participants will undergo a cue-reactivity paradigm followed by an alcohol challenge that includes an alcohol drink designed to raise the breath alcohol content (BrAC) to 0.08g/dL.
