What this trial studies

This study aims to compare the effectiveness of Prolonged Exposure (PE) therapy, pharmacotherapy with paroxetine or venlafaxine, and their combination for treating Posttraumatic Stress Disorder (PTSD) in military veterans. A randomized trial will involve 300 veterans recruited from six Veterans Affairs Medical Centers across the United States. Participants will undergo baseline assessments followed by up to 14 treatment sessions, which can be conducted in person or via telehealth to enhance accessibility. The study seeks to fill the gap in comparative effectiveness data for PTSD treatments, providing valuable insights for clinical decision-making.

Who should consider this trial

Good fit: Ideal candidates for this study are military veterans diagnosed with PTSD who are fluent in English and willing to participate in the treatment options provided.

Not a fit: Patients with recent suicidal ideation, active psychosis, or a history of failed trials with the treatments being tested may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could identify the most effective treatment options for PTSD, improving outcomes for veterans.

How similar studies have performed: Other studies have shown success in comparing PTSD treatments, but this study aims to provide more comprehensive data on the effectiveness of specific therapies and medications.
