Alcohol and Cigarette Craving During Oxytocin Treatment

Phase 1

Completed

• Conditions: Alcohol Use Disorder; Smoking
• Interventions: Drug: Oxytocin nasal spray; Drug: Placebo

• Registration Number: NCT04071119
• Lead Sponsor: Brown University

Brief Summary

This proposed research seeks to examine the behavioral and neural substrates of intranasal oxytocin compared to placebo on alcohol cue-induced alcohol and cigarette craving smokers with an alcohol use disorder (AUD). Non treatment-seeking smokers with an AUD will be recruited to participate in a between-subjects, placebo-controlled, randomized pilot functional magnetic resonance imaging (fMRI) study. Participants will undergo an fMRI scan in conjunction with an alcohol-olfactory cue-reactivity task. Secondary assessments will include alcohol and cigarette craving, alcohol and cigarette consumption, physiological measures (heart rate and blood pressure) and mood measures.
