Predictors of Treatment Response to Fluoxetine in PTSD Following a Recent History of War Zone Stress Exposure

Status unconfirmed · Phase 4 · Has a placebo group

Conditions studied: Posttraumatic Stress Disorder, Combat-related

In brief

Three hundred (300) male or female outpatients, over 18 years of age, will be enrolled in this study to determine whether fluoxetine can be used as a treatment for Posttraumatic Stress Disorder in soldiers recently returning from combat exposure. There will be two phases to the study. In Phase I Fluoxetine + usual psychological care will be compared with Placebo + usual psychological care over a 12-week period. Subsequently, in Phase II all subjects will be offered the opportunity to enroll in a 20-week open-label trial on Fluoxetine. If response is inadequate, adjunctive treatment with either buspirone or bupropion will be offered. The investigational drugs are Fluoxetine, Buspirone and Bupropion. All are commercially available.
