Pharmacological treatments for co-occurring PTSD and substance use disorders: A systematic review.

Introduction: Post-traumatic stress disorder and substance use disorders commonly co-occur and are associated with worse health outcomes. Currently, only psychosocial therapies are specifically recommended for use in the co-occurring population, but these come with numerous barriers to access and engagement. This study aims to identify potential pharmacological treatments to enhance treatment options and outcomes for this population.

Methods: This systematic review identified studies on pharmacological treatment of co-occurring PTSD and SUD in humans, using validated outcome measurements, with study design of RCT, observational study, case control study or cohort study.

Results: 29 studies were identified for inclusion, looking at a range of 16 pharmacotherapies. A majority concentrated on alcohol use disorders and males, with many focused on the veteran population.

Conclusions: This is an area for further research, inclusive of more SUDs, genders and civilians. Future studies utilizing consistent dosing, populations and measurement outcomes will allow for future meta-analysis.
