Research on Medications to Reduce Heavy Drinking in People Who Have Experienced Trauma

Pharmacogenetic Treatment with Anti-Glutaminergic Agents for Comorbid PTSD & AUD

The goal of this 14-week research study is to determine the impact of a medication called pregabalin in reducing heavy drinking and symptoms of post-traumatic stress disorder (PTSD). The study will also look at the safety and tolerability of pregabalin in participants with alcohol-use disorder and co-occurring PTSD.

Participants will have a screening visit to see if they are eligible. Those who are eligible are asked to complete weekly study visits for an additional 12 weeks that include taking study medication, providing information about drinking and PTSD symptoms, and completing a brief educational meeting. Bankole Johnson, MD, pictured at right on top, and Melanie Bennett, MD, are co-principal investigators.
