NCT03997864 · Status: WITHDRAWN · Phase: PHASE4 · Type: INTERVENTIONAL

No results posted yet for this study

Summary

This study plans to learn more about whether taking the medication, Prazosin, immediately and during the weeks immediately following a traumatic event can help to reduce the risk of developing posttraumatic stress disorder (PTSD). Early post traumatic event sleep disturbance predicts the later development of PTSD. Prazosin has shown some effectiveness in reducing trauma related nightmares and sleep disturbance. We hypothesize that regulating sleep immediately after a sexual assault will reduce PTSD and diminish symptoms.
