What this trial studies
This clinical trial is a randomized controlled, crossover, double-blind, placebo-controlled study involving non-treatment-seeking individuals with Alcohol Use Disorder (AUD). Participants will receive either intranasal insulin or a placebo in a controlled laboratory setting, followed by an alcohol challenge to assess the effects. The study aims to evaluate the safety, tolerability, and acceptability of intranasal insulin as a potential pharmacological intervention for AUD, as well as its interaction with alcohol. A total of 40 participants will be monitored for adverse events and physiological responses during the trial.
Why it matters
Potential benefit: If successful, this study could provide a novel pharmacological treatment option for individuals struggling with alcohol use disorder.
How similar studies have gone: While the approach of using intranasal insulin for AUD is novel, similar studies exploring pharmacological interventions for substance use disorders have shown promise.
