Trial of Psilocybin versus Escitalopram for Depression Robin Carhart-Harris, Ph.D., Bruna Giribaldi, B.Sc., Rosalind Watts, D.Clin.Psy., Michelle Baker-Jones, B.A., Ashleigh Murphy-Beiner, M.Sc., Roberta Murphy, M.D., Jonny Martell, M.D., Allan Blemings, M.Sc., David Erritzoe, M.D. and David J. Nutt, M.D.New England Journal of Medicine, 2021, 384, 1402-1411Doi : 10.1056/NEJMoa2032994 Abstract Background Psilocybin may have antidepressant properties, but direct comparisons between psilocybin and established treatments for depression are lacking. Methods In a phase 2, double-blind, randomized, controlled trial involving patients with long-standing, moderate-to-severe major depressive disorder, we compared psilocybin with escitalopram, a selective serotonin-reuptake inhibitor, over a 6-week period. Patients were assigned in a 1:1 ratio to receive [...]

Here, cerebral blood flow (CBF) and blood oxygen-level dependent (BOLD) resting-state functional connectivity (RSFC) were measured with functional magnetic resonance imaging (fMRI) before and after treatment with psilocybin (serotonin agonist) for treatment-resistant depression (TRD).

Le président de la République dresse le constat que « la France est devenue un pays de consommation ». La pénalisation de l’usage de drogues illégales n’a pourtant jamais été remise en cause depuis 51 ans, notre législation reste une des plus sévères et l’application des sanctions n’a cessé de se renforcer. Tout cela est parfaitement documenté par les travaux de l’OFDT et OEDT[1]. Sur la même période, prévention et réduction [...]

Psilocybin Delivers 'Remarkable' Relief in Severe Depression Batya Swift Yasgur, MA, LSW Medscape Medical News, November 05, 2020 Psilocybin, the psychedelic compound in "magic mushrooms," rapidly improves symptoms and produces remission in as little as two sessions for patients with major depression, new research suggests. Results of a small randomized trial showed that treatment with psilocybin was associated with a greater than 50% reduction in depressive symptoms in 67% of study participants. In addition, 71% showed improvement at 4-week follow-up, with more than 50% achieving remission. "The finding that the majority of people whom we treated showed efficacy was quite a remarkable and gratifying finding [...]
Lire la suitePsilocybin Matches SSRI for Moderate-to-Severe Depression in Phase 2 Study Sarah Edmonds Medscape Medical News, April 14, 2021 The psychedelic drug psilocybin performed just as well as a widely used antidepressant in easing the symptoms of major depression, and outperformed the selective serotonin reuptake inhibitor (SSRI) on a range of secondary measures, results of a small-scale phase 2 study show. In a 6-week trial that included 59 patients with moderate-to-severe depression, there was no significant difference between the impact of high-dose psilocybin on the study's primary yardstick — the 16-item Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR-16) — and that of selective serotonin reuptake [...]
Lire la suite'Magic Mushrooms' Effective for Severe Depression Batya Swift Yasgur, MA, LSW Medscape Medical News © 2017 October 20, 2017 Psilocybin, the psychoactive compound in “magic mushrooms,” is a promising intervention for patients with treatment-resistant depression (TRD) and appears to offer a rapid, sustained effect, new research shows. Investigators led by David Nutt, MD, PhD, professor of neuropsychopharmacology, Imperial College, London, United Kingdom, collected pre- and posttreatment fMRI data on the use of psilocybin in 19 patients with severe major depression who had failed to respond to conventional treatments. The patients experience dramatic improvements in depressive symptoms 1 day following treatment; close to half met criteria for full response at 5 [...]
Lire la suiteFDA Grants Psilocybin Second Breakthrough Therapy Designation for Resistant Depression Megan Brooks Medscape Medical News © 2019 November 25, 2019 The US Food and Drug Administration (FDA) has granted the Usona Institute breakthrough therapy designation for psilocybin for the treatment of major depressive disorder (MDD). This marks the second time the FDA has granted breakthrough designation for psilocybin, the psychoactive ingredient in "magic mushrooms." In October 2018, Compass Pathways received the designation to test the safety and efficacy of psilocybin-assisted therapy for treatment-resistant depression, as reported by Medscape Medical News. "The results from previous studies clearly demonstrate the remarkable potential for psilocybin as a treatment in MDD patients, which Usona is [...]

Doi :10.3390/ph14020078 Abstract : Cannabis has been widely used as a medicinal plant for millennia; however, studies related to its main components were first conducted in 1960. Subsequently, laboratories have produced new components and structures related to its active biological properties. Countries that have approved the medicinal use of cannabis impose regulations that govern its clinical and scientific use. One means of administering medicinal cannabis is via a magistral preparation that must have a medical prescription and be prepared in an establishment [...]

Doi : 10.3390/ph14020171 Abstract : Current legislation in Italy provides that medical Cannabis may be administered orally or by inhalation. One of the fundamental criteria for the administration of oral formulations is that they deliver a known consistent quantity of the active ingredients to ensure uniform therapies leading to the optimisation of the risks/benefits. In 2018, our group developed an improved Cannabis oil extraction technique. The objective of [...]
