简要总结
The purpose of the study is to evaluate if the drug prazosin:
- will decrease alcohol use in active duty members of the military who served in Iraq and/or Afghanistan and
- determine if presence or absence of posttraumatic stress disorder affects treatment.
详细描述
The proposed study is a 19-week, titration to stable dose, randomized, two-group parallel-design, double-blind, placebo-controlled trial to evaluate the efficacy of prazosin for decreasing alcohol use in 200 active duty Service Members who served in the conflicts in Iraq and/or Afghanistan who are receiving standard outpatient treatment for alcohol use disorders at Joint Base Lewis-McChord. Treatment groups will be stratified by presence or absence of posttraumatic stress disorder (PTSD) and by assignment to the 6-week or 12-week Army Substance Abuse Program. The hypotheses are that: 1) prazosin is more effective than placebo for alcohol use disorders in these Service Members; and 2) that prazosin effect size will be greater in Service Members with PTSD than without PTSD.

结局指标
主要结局
Change in Penn Alcohol Craving Scale Score
时间窗: Change at Week 13 from Baseline
Penn Alcohol Craving Scale (PACS) The PACS is a self-report paper-and-pencil instrument. This five-item, self-report measure includes questions about the frequency, intensity, and duration of craving, the ability to resist drinking, and asks for an overall rating of craving for alcohol for the previous week. Each question is scaled from 0 to 6. Total scores are 0 to 30. Lower scores indicate less alcohol craving. Higher scores indicate more alcohol craving.
