Cell Reports Medicine January 1, 2023 DOI: 10.1016/j.xcrm.2022.100906
Summary
A single 25 mg dose of psilocybin offers a compelling short-term antidepressant effect for medication-resistant depression. This potent psychedelic alkaloid, often produced via chemical synthesis, demonstrates a unique pharmacology. Its mechanism of action likely involves altering neurotransmitter receptor influence on behavior, a key area of neuroscience and psychology. This promising action suggests new avenues for drug studies, though understanding the full biological mechanism and potential risks is vital for future development.
Abstract
Goodwin et al.1 report a single 25 mg dose of psilocybin has an antidepressant effect short-term in medication-resistant depression. Unanswered questions include drug blood level as a guide to dose, psychedelic effects relationship to antidepressant benefit, and potential suicide risk of psilocybin.
