About
The proposed project aims to:
PRIMARY HYPOTHESIS: Topiramate treatment combined with Medical Management alcohol counseling will be associated with a significant decrease in percent drinking days from baseline to end of treatment.
SECONDARY HYPOTHESIS: There will be significantly less percent drinking days in the topiramate treatment group compared to the placebo group.
Full description
The goal of the proposed project is to improve the treatment of veterans with co-occurring Post Traumatic Stress Disorder (PTSD) and alcohol dependence. Exposure to the stresses of combat is known to be associated with risk for both PTSD and alcohol and other substance use. PTSD and alcohol use disorders occur frequently among returning OEF/OIF veterans. Alcohol and substance use are risk factors for the development of PTSD, moderators of PTSD symptom severity, and potential consequences of PTSD. Alcohol is by far the most common substance of abuse in patients with PTSD, and its use may represent an attempt by PTSD patients to "self-medicate" symptoms such as hyperarousal. However, to date there has been little research to develop pharmacotherapies that would, ideally, reduce both alcohol use and PTSD symptoms.
Topiramate is one of the few medications for alcohol dependence that has also been tested as a potential medication to treat PTSD. Topiramate's efficacy in alcohol dependence has been shown in two recent large controlled trials. Several open trials have suggested that topiramate may be effective in reducing PTSD symptoms while the results of two small controlled trials have been mixed.
A clinical trial of topiramate is therefore indicated in order to achieve the following specific aims:
The primary aim is to obtain a preliminary assessment of the efficacy of topiramate in increasing the percent of days abstinent from alcohol use from baseline to the end of treatment in veterans with PTSD and alcohol abuse/dependence who are drinking heavily.
The secondary aim is to obtain a preliminary assessment of the efficacy of topiramate in increasing the percent of days abstinent from alcohol as compared to placebo.
Additional aims include the following:
To achieve these aims, we will conduct a prospective, parallel groups, randomized, double-blind, placebo-controlled flexible-dose pilot clinical trial of topiramate in veterans with PTSD and alcohol abuse/dependence who are already receiving standard treatment for PTSD but still drink heavily. The primary treatment outcome will be percent days abstinent from alcohol; secondary outcomes will include other alcohol use measures, PTSD symptom severity, adverse effects, recruitment and retention rates.
