Conditions
Summary
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.
Eligibility
Inclusion Criteria8

- Individuals who, in the last month, have consumed at least the same amount of alcohol that will be administered in the laboratory procedure (i.e. to reach BrAC levels of 0.08g/dl, ~two drinks in one occasion)
- BrAC=0.00g/dL at each visit
- good health as confirmed by medical history, physical examination and lab tests
- willing to adhere to the study procedures
- understand informed consent and questionnaires in English at an 8th grade level
- willing to have glucose monitored by finger stick during the laboratory procedures

- use of medications that may interact with insulin and alcohol (by Micromedex database)
- hypersensitivity to insulin
- any nasal disease/congestion that may interfere with intranasal drug absorption;
- baseline hypoglycemia (blood glucose ≤65mg/dL) or hyperglycemia (blood glucose >200mg/dL) (by finger stick)
