Brief Summary:
The purpose of this study is to determine whether prazosin will reduce the incidence of nightmares, sleep disturbance, and overall symptoms in combat trauma-exposed individuals with PTSD.
Detailed Description:
The combat stress-related nightmares and sleep disturbance that often follow exposure to military combat are distressing and frequently persistent symptoms that impair quality of life and both occupational and social (e.g., family) function. One of the most frequently reported and most troubling symptoms of PTSD is trauma-content nightmares. These nighttime symptoms have been notoriously resistant to treatment with psychotropic medications such as anxiolytics, the SSRIs, and sedating antihistamines such as cyproheptadine. The SSRIs sertraline (Zoloft®) and paroxetine (Paxil®) are the only drugs FDA approved for PTSD. This approval was based on modest overall PTSD improvement compared to placebo in large multicenter trials that enrolled almost exclusively noncombat trauma subjects. Placebo-controlled SSRI trials for PTSD in combat veterans have been negative or equivocal.
Neurobiologic data suggest that combat stress-related nightmares and sleep disturbance in PTSD are related to enhanced central nervous system (CNS) adrenergic activity, particularly at night. Prazosin is a CNS-active, non-sedating alpha-1 antagonist that has long been generically available for the treatment of hypertension and benign prostatic hypertrophy. We recently demonstrated in Vietnam combat veterans with chronic PTSD that prazosin is robustly effective for previously treatment refractory combat trauma related nightmares, sleep disturbance and overall PTSD severity and functional impairment.
The goal of this study is to evaluate the efficacy and tolerability of prazosin compared to placebo for combat stress-related nightmares, sleep disturbance and overall function in combat-trauma exposed persons with PTSD.
Primary outcome measures will be Clinical Global Impression of Change, Recurrent Distressing Dreams and Difficulty Falling and Staying Asleep items of the CAPS, total CAPS (exclusive of the dreams and sleep items), and the Pittsburgh Sleep Quality Index. Depression and quality of life also will be assessed.
