Psychedelic therapeutics in psychiatric conditions

Neuropsychopharmacology January 16, 2026 Philip D. Harvey, Charles B. Nemeroff 2 citations

Interest in psychedelic therapies is booming, yet no psychedelic treatment has been approved for any psychiatric condition. The one large-scale MDMA development program that reached the FDA was disapproved for reasons that could also apply to classical psychedelic trials. This review defines psychedelics, surveys current therapies, targeted conditions, compounds under investigation, and research strategies. Some interventions combine drugs with psychotherapy, bringing both benefits and challenges. Debate continues over whether the psychedelic experience itself is essential for therapeutic effect, complicating blinded trials. The review also addresses societal issues like deregulation of formerly illegal substances and regulatory hurdles, including alternatives to blinded trials and whether targets like adjustment disorder pose problems under current standards.

Efficacy of Intravenous Racemic Ketamine on Global Severity and Individual Symptoms of Depression

Journal of Clinical Psychopharmacology September 25, 2025 Rachel Landrum, Amanda M. Raines, Philip D. Harvey et al. 1 citation

Maintenance intravenous racemic ketamine therapy produced significant, persistent, and broad symptom relief for treatment-resistant depression. Reductions occurred in both clinician-rated (Montgomery-Åsberg Depression Rating Scale) and patient-reported (Patient-Health Questionnaire-9) depression scores. Changes in individual symptoms were similar to prior trials: suicidal ideation and depressed mood improved most, while appetite disturbance improved least.
