Detailed Description:

The primary treatment objective is to assess the global efficacy of nepicastat in the treatment of hyper-arousal in Post Traumatic Stress Disorder (PTSD) in conflict or combat zone experienced veterans, in comparison to placebo. The secondary treatment objectives are to assess the ability of nepicastat to induce PTSD remission; treat PTSD and other PTSD symptom clusters and improve quality of life and overall functioning. A medical safety objective is to assess the tolerability and side effects of nepicastat in the treatment of PTSD in veterans who served in conflict zones at least one time between 1990 -2008 [includes Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF), Afghanistan, Gulf War, etc .

This is a 6-week study with the long-term objective is to define the best approach to treating PTSD and enhancing the quality of life in patients. Results from this pilot study will assist clinicians in treating active military service members or veterans with PTSD by developing new treatment algorithms for future larger studies.
