About this study

This trial is testing if a combination of ketamine, midazolam, and intensive trauma-focused psychotherapy will be more effective in treating post-traumatic stress disorder (PTSD) than usual care. The goal is to see if this week-long treatment can provide significant relief that would normally take months to achieve. Researchers are also studying the brain changes caused by this clinical trial.

Based on ClinicalTrials.gov records.
