All pharmaceutical treatments for prevention of PTSD

Can PTSD be prevented?

Scientific understanding of the neurobiological changes occurring during PTSD onset shows memory consolidation appears particularly vulnerable to disruption in the first six hours after trauma, making this a crucial period for intervention for prevention of PTSD. This technical commentary presents the evidence on pharmaceutical interventions administered during this period.

What is the evidence on pharmaceutical interventions for prevention of PTSD?

Hydrocortisone is a glucocorticoid, which attenuates heightened fear response through increased removal of fear-inducing memories. Moderate to low quality evidence found a medium to large, reduced risk of PTSD within 3-6 months post-trauma in people with severe physical illness or injury receiving hydrocortisone post-trauma. Risks were not assessed in these samples, so contraindications need checking.

There was no benefit of hydrocortisone over placebo after 6 months post-trauma. There were also no benefits of propranolol, oxytocin, gabapentin, fish oil, dexamethasone, escitalopram, imipramine, or chloral hydrate for preventing PTSD at any time frame. Studies are few and small.
