AIMS: This study aimed to evaluate the safety, tolerability and pharmacokinetics of a novel oral modified-release psilocybin formulation (REL-P11) in normal-weight and overweight/obese healthy adults and to assess its suitability for controlled, subperceptual exposure, in light of emerging evidence supporting serotonergic modulation in metabolic disorders. METHODS: Simulation-based modelling...

The therapeutic potential of low, non-psychedelic doses of psilocybin, a fungal tryptamine alkaloid, was investigated in metabolic disorders including obesity, type 2 diabetes mellitus (T2DM), and liver steatosis. Mice fed a high-fat/high-fructose diet received chronic treatment with psilocybin (0.05 mg/kg) for 12 weeks. Body weight, liver histology, insulin sensitivity, and skeletal muscle...

Abstract Background For centuries, American indigenous populations have utilized psilocybin-containing mushrooms for both traditional medical and religious purposes, often in the context of psychedelic experiences. More recently, there has been a notable increase in the interest for and in the practice of psilocybin 'microdosing': regular intake of psilocybin-containing mushrooms in amounts...

This article presents a mechanism of action hypothesis to explain the rapid antidepressant effects of esmethadone (REL-1017) and other uncompetitive N-methyl-D-aspartate receptor (NMDAR) antagonists and presents a corresponding mechanism of disease hypothesis for major depressive disorder (MDD). Esmethadone and other uncompetitive NMDAR antagonists may restore physiological neural plasticity in...

OBJECTIVE The purpose of this study was to examine the effects of REL-1017 (esmethadone), a novel N-methyl-d-aspartate receptor (NMDAR) channel blocker, in patients with major depressive disorder who failed to benefit from one to three standard antidepressant treatments in their current major depressive episode. METHODS A 7-day phase 2 multicenter randomized double-blind placebo-controlled...
