Methylone and MDMA Pharmacokinetics Following Controlled Administration in Humans

In a first controlled human study, oral methylone (50–200 mg) showed rapid, dose‑proportional (linear) pharmacokinetics with Cmax and AUC increasing proportionally, Tmax ≈1.5–2 h and t1/2 ≈6–7 h. A validated LC–MS/MS assay quantified methylone, MDMA and metabolites and found the primary metabolite HMMC had much lower exposure (Cmax ~10–14× and AUC ~21–29× lower) and faster kinetics than the parent drug.

Effect of Psilocybin and Ketamine on Brain Neurotransmitters, Glutamate Receptors, DNA and Rat Behavior

A single dose of ketamine (10 mg/kg) or psilocybin (2 and 10 mg/kg) in rats acutely increased extracellular dopamine, serotonin, glutamate and GABA in the frontal cortex (psilocybin also raised GABA in the thalamic reticular nucleus), induced oxidative DNA damage (psilocybin in frontal cortex; both drugs in hippocampus) and upregulated the NR2A glutamate receptor subunit after high-dose psilocybin. These neurochemical and genotoxic changes occurred without detectable antidepressant or anxiolytic behavioural effects 24 h later, although ketamine reduced locomotor activity.
