High dose of psilocybin effective for treatment-resistant depression
Adults with treatment-resistant depression who received a single 25-mg dose of psilocybin saw significant improvement in depressive symptoms relative to a control dose at 3 weeks, a Phase 2b trial has found. A smaller 10-mg dose of psilocybin did not result in significant improvement over the control dose of 1 mg, and adverse events were common in both of the higher-dose groups. Study results were published in the Nov. 3, 2022 issue of The New England Journal of Medicine.
