Summary
Psilocybin, a potent hallucinogen, demonstrates high antidepressant potential for Major Depressive Disorder, sparking renewed interest in psychiatry. Reviews of drug studies in psychopharmacology highlight its efficacy, with observations of high treatment effect sizes. While the precise mechanisms by which this alkaloid influences neurotransmitter receptors and behavior are still being fully elucidated in medicine and psychology, its role as a potential antidepressant is significant. Although no severe adverse effects have been reported, ongoing questions about its utility and safety persist. This area of psychedelics research continues to evolve.
Abstract
There has recently been a renewal of interest in psychedelic research on the use of psilocybin in psychiatric treatment and, in particular, for the treatment of major depressive disorder (MDD). Several state-of-the-art studies have provided new insight into the mechanisms of action of psilocybin and its therapeutic potential. Nevertheless, many questions remain unanswered. With this review, we provide an overview of the current state of research on the potential mechanisms of psilocybin, its antidepressant potential, and the associated risks and adverse effects, to provide an update on a controversial topic discussed in psychopharmacology. A database search was conducted in Medline including articles on psilocybin over the period of the last 20 years. Despite the promising progress in understanding the mechanisms of psilocybin, the exact antidepressive mechanism and the role of the psychedelic experience remain elusive. The studies included in this review found high treatment effect sizes for psilocybin as an antidepressant. However, the results must be regarded as preliminary due to several limitations. Although the current studies observed no severe adverse events, several questions regarding safety and utility remain and must be subject of future research.
