Psilocybin: from ancient magic to modern medicine

February 6, 2022 / History, Mushrooms / Psilocybin, Papers / Leave a Comment / By /

Abstract

Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) is an indole-based secondary metabolite produced by numerous species of mushrooms. South American Aztec Indians referred to them as teonanacatl, meaning “god’s flesh,” and they were used in religious and healing rituals. Spanish missionaries in the 1500s attempted to destroy all records and evidence of the use of these mushrooms. Nevertheless, a 16th century Spanish Franciscan friar and historian mentioned teonanacatl in his extensive writings, intriguing 20th century ethnopharmacologists and leading to a decades-long search for the identity of teonanacatl. Their search ultimately led to a 1957 photo-essay in a popular magazine, describing for the Western world the use of these mushrooms. Specimens were ultimately obtained, and their active principle identified and chemically synthesized. In the past 10-15 years several FDA-approved clinical studies have indicated potential medical value for psilocybin-assisted psychotherapy in treating depression, anxiety, and certain addictions. At present, assuming that the early clinical studies can be validated by larger studies, psilocybin is poised to make a significant impact on treatments available to psychiatric medicine.

Abstract

Objective: To compare esketamine to placebo, each in addition to standard-of-care treatment, for rapidly reducing major depressive disorder symptoms, including suicidal ideation.
Methods: This phase 3, double-blind, multicenter study (ASPIRE I), conducted between June 2017 and December 2018, enrolled 226 adults having major depressive disorder based on Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) criteria, active suicidal ideation with intent, and need for psychiatric hospitalization. Patients were randomized 1:1 to esketamine 84 mg or placebo nasal spray twice-weekly for 4 weeks, each with comprehensive standard-of-care treatment (initial psychiatric hospitalization and newly initiated or optimized oral antidepressant[s] therapy). Change from baseline to 24 hours post-first dose in Montgomery-Asberg Depression Rating Scale (MADRS) total score (primary endpoint) was analyzed using analysis of covariance (ANCOVA), and change in Clinical Global Impression of Severity of Suicidality Revised version (CGI-SS-r; key secondary endpoint) score was analyzed using ANCOVA on ranks with treatment difference estimated using the Hodges-Lehmann estimate.
Results: Greater improvement in MADRS total score was observed with esketamine + standard-of-care versus placebo + standard-of-care at 24 hours (least-squares mean difference [SE]: -3.8 [1.39]; 95% CI, -6.56 to -1.09; 2-sided P = .006), as well as at earlier (4 hours) and later time points during 4-week double-blind treatment. The difference between groups in the severity of suicidality was not statistically significant (median of treatment difference [95% CI]: 0.0 [-1.00 to 0.00]; 2-sided P = .107). The most common adverse events among esketamine-treated patients were dizziness, dissociation, headache, nausea, and somnolence.
Conclusions: These findings demonstrate rapid and robust efficacy of esketamine nasal spray in reducing depressive symptoms in severely ill patients with major depressive disorder who have active suicidal ideation with intent.

MDMA-assisted psychotherapy for people diagnosed with treatment-resistant PTSD: what it is and what it isn’t

May 12, 2020 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychology, Psychopharmacology, Publications / By /

Abstract

Background

PTSD is a chronic condition with high rates of comorbidity, but current treatment options are limited and not always effective. One novel approach is MDMA-assisted psychotherapy for people diagnosed with treatment-resistant PTSD, where MDMA is used as a catalyst to facilitate trauma processing during psychotherapy. The aim was to review all current research into MDMA-assisted psychotherapy for PTSD.

Methods

Articles were identified through PubMed and Science Direct for items published up to 31st March 2019 using terms “treatments for PTSD”, “drug treatments for PTSD”, “MDMA”, “MDMA pathway”, “MDMA-assisted psychotherapy” and “MDMA-assisted psychotherapy for PTSD”. Articles were identified through Google Scholar and subject-specific websites. Articles and relevant references cited in those articles were reviewed.

Results

Small-scale studies have shown reduced psychological trauma, however there has been widespread misunderstanding of the aims and implications of this work, most commonly the notion that MDMA is a ‘treatment for PTSD’, which to date has not been researched. This has harmful consequences, namely dangerous media reporting and impeding research progression in an already controversial field.

Conclusions

MDMA-assisted psychotherapy may help people who have experienced psychological trauma and who have not been able to resolve their problems through existing treatments, however more research is needed. If this is to get appropriate research attention, we must report this accurately and objectively.
