Official Title: A Double-Blind, Placebo-Controlled, Flexible-Dose Pilot Clinical Trial of Once-Daily Extended-Release Tramadol for the Treatment of PTSD
Brief Summary: This is a six-week pilot study testing the efficacy of tramadol extended-release (ER) for posttraumatic stress disorder (PTSD). Men and women aged 21-55 years with combat-related PTSD (n = more than 20) or PTSD resulting from a civilian trauma (n = fewer than 20) will be recruited. Blinded tramadol ER will begin with a 100 mg daily dose for the first week, with an option to increase to 200 mg/day for the 2nd week. Dose adjustments, using a range of 100-300 mg tramadol ER per day (or 1 to 3 placebo tabs), are permitted thereafter. The primary hypothesis is that tramadol ER 100 to 300 mg every morning for 6 weeks will reduce the symptoms of PTSD relative to placebo. The primary outcome measures will be PTSD symptoms as rated by the Clinician-Administered PTSD Scale (CAPS) and Clinicians Global Impressions scale at baseline and weeks one, two, four, and six. Assignment to blinded medication arms will be stratified to ensure equivalence of the two arms (men and women, military and civilian trauma).
