Cannabidiol (CBD) may prevent haloperidol-induced orofacial dyskinesia, according to new research being published by the journal Brain, Behavior, and Immunity; the research was epublished by the National Institute of Health.
“The chronic use of drugs that reduce the dopaminergic neurotransmission can cause a hyperkinetic movement disorder called tardive dyskinesia (TD)”, states the study’s abstract. “The pathophysiology of this disorder is not entirely understood but could involve oxidative and neuroinflammatory mechanisms. Cannabidiol (CBD), the major non-psychotomimetic compound present in Cannabis sativa plant, could be a possible therapeutic alternative for TD.”
The study states that “This phytocannabinoid shows antioxidant, anti-inflammatory and antipsychotic properties and decreases the acute motor effects of classical antipsychotics. The present study investigated if CBD would attenuate orofacial dyskinesia, oxidative stress and inflammatory changes induced by chronic administration of haloperidol in mice.”
Furthermore, researchers “verified in vivo and in vitro (in primary microglial culture) whether these effects would be mediated by PPARγ receptors. The results showed that the male Swiss mice treated daily for 21 days with haloperidol develop orofacial dyskinesia. Daily CBD administration before each haloperidol injection prevented this effect.”
Mice treated with haloperidol “showed an increase in microglial activation and inflammatory mediators in the striatum. These changes were also reduced by
