This trial proposes to test whether a single dose of hydrocortisone, administered within six hours of exposure to trauma, can prevent the development of post-traumatic stress disorder (PTSD).

Who is the study for?
This trial is for adults who've recently experienced trauma, feel highly distressed or disconnected, and have a heart rate of 80 bpm or more. They must weigh between 99-242 lbs and not be severely injured, intoxicated, pregnant, on steroids or benzodiazepines, nor have certain chronic diseases or mental health conditions.Check my eligibility
What is being tested?
The study tests if a single dose of hydrocortisone (HCORT), given within six hours after trauma can prevent PTSD compared to a placebo. It's randomized with assessments at multiple intervals post-treatment to measure the decline in PTSD symptoms and related mental health issues.See study design
What are the potential side effects?
Potential side effects are not detailed but may include those typical of corticosteroids like mood swings, increased blood pressure, sleep problems, weight gain, and elevated blood sugar levels.

Mechanism Of Action

Other Research
Common treatments for Post-Traumatic Stress Disorder (PTSD) work by targeting different aspects of the body's stress response. Hydrocortisone, for example, mimics cortisol, a hormone that helps the body recover from stress, potentially reducing PTSD symptoms and promoting resilience. SSRIs and SNRIs increase serotonin and norepinephrine levels in the brain, which can improve mood and reduce anxiety. Prazosin, an alpha-adrenergic receptor blocker, helps reduce nightmares and improve sleep by blocking adrenaline's effects. Understanding these mechanisms is important for PTSD patients as it allows for more personalized and effective treatment strategies.
