What was done
This paper is a narrative review evaluating existing studies that used panicogenic challenge agents (such as sodium lactate, carbon dioxide, and cholecystokinin tetrapeptide) to provoke anxiety and related psychopathological symptoms experimentally in patients with post-traumatic stress disorder (PTSD).
What was found
The abstract reports no numerical data, effect sizes, or participant numbers. It qualitatively reports that several panicogenic agents can induce both classic panic anxiety and PTSD-specific psychopathology, including flashbacks and dissociative symptoms, under controlled experimental conditions.
Why it matters
Panicogen challenge paradigms offer a translational model to investigate the neurobiological mechanisms underlying PTSD and could inform the development of novel therapeutic targets.
Limits
The abstract does not disclose the number of studies reviewed, sample sizes, or quantitative results. As a narrative review, it lacks systematic search methodology, and the authors note methodological shortcomings in the primary literature.
