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

Summary

The primary study objective is to determine the efficacy of pregabalin administered orally for a period of 12 weeks in reducing risky drinking and symptoms of posttraumatic stress disorder who have selected genotypes at the gamma-amino butyric acid transporter and receptor genes. The secondary objective is to assess the safety and tolerability of pregabalin in participants with alcohol use disorder and co-occurring posttraumatic stress disorder who have selected genotypes at the gamma-amino butyric acid transporter and receptor genes. The investigators will utilize a sample of African-Americans that includes both genders and individuals with different types of trauma.
