Maia-de-Oliveira, L. Wichert-Ana, D.B. de Araujo, J. Riba, J.A. Crippa, J.E. Hallak Journal of Clinical Psychopharmacology, 2016, 36, 1, 77-81. doi: 10.1097/JCP.0000000000000436. PMID : 26650973 Abstract Ayahuasca is an Amazonian botanical hallucinogenic brew which contains dimethyltryptamine, a 5-HT2A receptor agonist, and harmine, a monoamine-oxidase A inhibitor. Our group recently reported that ayahuasca administration was associated with fast-acting antidepressive effects in 6 depressive patients. The objective of the present work was to assess the antidepressive potentials of [...]

Ces utilisations thérapeutiques concernaient, à l’origine, essentiellement « l’accompagnement » des psychothérapies (thérapies psycholytiques), le traitement des addictions (alcool, puis opiacés) et, du fait de leurs capacités anxiolytiques et antidépressives, la prise en charge des troubles psychologiques post-traumatiques, les dépressions résistantes, les pathologies obsessionnelles et psychosomatiques (douleurs, migraines…) et l’accompagnement des fins [...]

Van HELL, Arno HAZEKAMP BMC Pharmacol Toxicol, 2014, 15, 58 Published online 2014 Oct 16. doi: 10.1186/2050-6511-15-58 PMCID: PMC4274767 PMID: 25319497 Abstract Background Significant interest has emerged in the therapeutic and interactive effects of different cannabinoids. Cannabidiol (CBD) has been shown to have anxiolytic and antipsychotic effects with high doses administered orally. We report a series of studies conducted to determine the vaporisation efficiency of high doses of CBD, alone and in combination with ∆9-tetrahydrocannabinol (THC), to achieve faster onset effects in experimental and clinical [...]
Lire la suiteProspects for the Use of Cannabinoids in Oncology and Palliative Care Practice: A Review of the Evidence. Tomasz DZIERZANOWSKI Cancers (Basel), 2019, 11, 2 Abstract There is an increased interest in the use of cannabinoids in the treatment of symptoms in cancer and palliative care patients. Their multimodal action, in spite of limited efficacy, may make them an attractive alternative, particularly in patients with multiple concomitant symptoms of mild and moderate intensity. There is evidence to indicate cannabis in the treatment of pain, spasticity, seizures, sleep disorders, nausea and vomiting, and Tourette syndrome. Although the effectiveness of cannabinoids is limited, it was confirmed in [...]

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2019, 8, 89, 90-96. doi: 10.1016/j.pnpbp.2018.08.030 Abstract Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication, restricted and repetitive patterns of behavior, interests, or activities and often intellectual disabilities. ASD has a number of prevalent co-morbidities, such as sleep disorders, attention deficit/hyperactivity disorder and epilepsy. No effective treatment for the core symptoms of ASD is currently available. There is increasing interest in cannabinoids, especially cannabidiol (CBD), as monotherapy or add-on treatment for the core symptoms and co-morbidities [...]

While it is well established that ASD stems from a combination of genetic and environmental factors, there are no defined mechanisms of pathogenesis, rendering curative therapy very difficult to establish. No effective therapy exists for ASD, presenting an urgent clinical need for better control of common core pathologies of ASD regardless of its etiology. Cannabidiol (CBD), a major phytocannabinoid constituent of the cannabis plant, is [...]
