Summary

This study tests whether giving the drug propranolol (a beta-blocker) soon after a sexual assault can prevent post-traumatic stress disorder (PTSD). 34 adult women who seek help within 72 hours will take either propranolol or a placebo for 10 days, then a lower dose for another 14 days. Researchers will check for PTSD symptoms at 5 weeks using a standard interview. The idea is that propranolol may weaken the traumatic memory during its reconsolidation phase, reducing the risk of developing PTSD.
