Intranasal Oxytocin Hypothesized to Prevent PTSD Development by Facilitating Physiological Recovery Post-Trauma

Acute stress exposure is a primary trigger for Post Traumatic Stress Disorder (PTSD), a debilitating condition with significant long-term impact. Current interventions often focus on treatment post-diagnosis, or are time/energy intensive for prevention. There's a critical need for prophylactic strategies that enhance psychological resilience immediately following trauma. Oxytocin, a neuropeptide known for its roles in social bonding and stress regulation, is being explored for its potential to modulate fear learning and facilitate physiological recovery, offering a promising candidate for early intervention.

This Phase 2, randomized, quadruple-blinded, treatment study (NCT03238924) enrolled 17 participants. The intervention involves a single administration of intranasal oxytocin within 6 hours post-trauma. The control arm received a placebo. The primary hypothesis is that oxytocin facilitates physiological recovery from trauma, thereby preventing PTSD development in the months following the event, compared to placebo conditions where a greater proportion of persons are expected to develop PTSD.
