PTSD and ketamine research
An overview of post-traumatic stress disorder, established trauma-focused therapies, and the developing evidence on ketamine-assisted approaches.
Overview
Post-traumatic stress disorder (PTSD) can develop after exposure to traumatic events and includes intrusion symptoms, avoidance, negative changes in mood and cognition, and altered arousal. PTSD is highly treatable, especially with trauma-focused psychotherapy.
Conventional treatment
Trauma-focused therapies such as Prolonged Exposure, Cognitive Processing Therapy, and EMDR have strong evidence. SSRIs (sertraline and paroxetine) are FDA-approved for PTSD.
Where ketamine fits
Studies of ketamine in PTSD — including repeated-dose IV protocols — have shown short-term reductions in symptom severity in some adults. Interest in combining ketamine with structured psychotherapy is growing, but well-controlled trials of integrated protocols are still limited.
What current evidence suggests
A small but expanding evidence base supports the potential of ketamine to acutely reduce PTSD symptoms in some patients. Long-term efficacy, optimal pairing with therapy, and comparative effectiveness versus established treatments remain open questions.
Frequently asked questions
Can ketamine replace trauma therapy?+
No. Trauma-focused psychotherapies remain the standard of care for PTSD. Ketamine is generally considered as an adjunct, not a replacement.
