Commentary
Following a case study of the anticholinergic drug scopolamine butyl bromide, this study investigates the effects of a central anticholinergic drug on post-traumatic stress disorder (PTSD)-related flashbacks and nightmares.
We administered trihexyphenidyl (TP) fireproofing to 34 patients with PTSD-related nightmares and flashbacks who had previously received psychiatric treatment for about 2-15 had been on for years without treatment effect.
The effects of TP were determined using the Clinician-Administered PTSD Scale (CAPS) and the Impact of Events Scale - Revised (IES-R).
As a result, most patients reported no or mild improvement in the CAPS for nightmares (88%) and flashbacks (79%).
Conclusion
This study is the first to demonstrate the potential efficacy of TP in the treatment of refractory PTSD-related nightmares and flashbacks; further double-blind randomized controlled trials are needed to investigate the potential clinical benefits of TP in PTSD.
