Psilocybin-assisted therapy for depression: A systematic review and dose-response meta-analysis of human studies

The highlights section of this free, full-text European Neuropsychopharmacology article comments:

  • Resistant patients mostly respond to higher dose of psilocybin (ED95: 40 mg/70 kg).
  • The near maximal effective dose was much lower for secondary depression than for primary depression (ED95: 8.92 and 24.68 mg/70 kg respectively).
  • Patients with comorbid anxiety may respond better to lower doses of psilocybin for both depressive and anxiety symptoms reduction.
  • Psilocybin is generally well-tolerated, with transient and mild to moderate adverse events such as headache and nausea.
  • In controlled conditions, psychological discomfort during psychedelic trips can occur at higher doses, but panic reactions are easily managed with psychological support.
