What this trial studies

This study investigates the effects of pioglitazone, a medication typically used for diabetes, on stress-induced relapse risk and alcohol cravings in individuals with Alcohol Use Disorder. Participants will be treated with either pioglitazone or a placebo while their drinking behaviors, stress levels, and anxiety are monitored in both controlled laboratory settings and natural environments. The study aims to understand how this medication may help reduce cravings and improve stress management in those seeking treatment for alcohol use issues.

Who should consider this trial

Good fit: Ideal candidates are treatment-seeking individuals diagnosed with Alcohol Use Disorder who experience mild to moderate anxiety and increased stress reactivity.

Not a fit: Patients with severe anxiety, PTSD, or those not seeking treatment for Alcohol Use Disorder may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic approach to help individuals with Alcohol Use Disorder manage cravings and reduce relapse risk.

How similar studies have performed: While the use of pioglitazone for this purpose is novel, similar studies exploring pharmacological interventions for alcohol cravings have shown promise.
