A Phase 1, Open-Label, Pharmacokinetic Trial to Investigate Possible Drug-Drug Interactions Between Clobazam, Stiripentol, or Valproate and Cannabidiol in Healthy Subjects. G. Morrison, J. Crockett, G. Blakey, K. Sommerville Clinical Pharmacology in Drug Development, 2019, PMID : 30791225, DOI : 10.1002/cpdd.665 Abstract GW Pharmaceuticals' formulation of highly purified cannabidiol oral solution is approved in the United States for seizures associated with Lennox-Gastaut and Dravet syndromes in patients aged ≥2 years, for which clobazam, stiripentol, and valproate are commonly used antiepileptic drugs. This open-label, fixed-sequence, drug-drug interaction, healthy volunteer trial investigated the impact of cannabidiol on steady-state pharmacokinetics of clobazam (and N-desmethylclobazam), stiripentol, and valproate; [...]
Lire la suiteVariétés de Cannabis: Par Docteur Ethan Russo http://www.cannabis-med.org/index.php?tpl=faq&red=faqlist&id=172&lng=fr Les consommateurs de cannabis ont souvent indiqué que les différentes variétés de cannabis produisent des effets variables, que se soit concernant les effets psychoactifs ou les bénéfices thérapeutiques. Les variétés sont généralement désignées comme étant soit Sativa, soit Indica, soit hybrides. Or, ces noms, d’un point de vue commercial, prêtent à confusion. Pour cette raison, la communauté scientifique s’est concentrée sur le Tétrahydrocannabinol (THC) qu’elle considérait comme la principale variable et la seule d’importance. En parallèle, jusqu’à très récemment, les croisements sélectifs des variétés de cannabis, destiné à l’usage récréatif ou à l’usage thérapeutique, [...]

Nutt Psychopharmacology, 2017 https://doi.org/10.1007/s00213-017-4771-x Abstract : Rationale : Recent clinical trials are reporting marked improvements in mental health outcomes with psychedelic drug-assisted psychotherapy. Objectives : Here, we report on safety and efficacy outcomes for up to 6 months in an open-label trial of psilocybin for treatment-resistant depression. Methods : Twenty patients (six females) with (mostly) severe, unipolar, treatment-resistant [...]

DOI : 10.1177/0269881118780714 Abstract Background : Recent research on psychedelics and hypnosis demonstrates the value of both methods in the treatment of a range of psychopathologies with overlapping applications and neurophenomenological features. The potential of harnessing the power of suggestion to influence the phenomenological response to psychedelics toward more therapeutic action has remained unexplored in recent research and thereby warrants empirical attention. Aims : Here we aim to elucidate the phenomenological and neurophysiological similarities and dissimilarities between psychedelic states and hypnosis in order to revisit [...]

Patricia Schonhofen, Ivi Juliana Bristot, José Alexandre Crippa, Jaime Eduardo Cecilio Hallak, Antonio Waldo Zuardi, Richard B. Parsons, Fabio Klamt CNS Drugs, 2018, 32 (Suppl 1), 1-16 https///doi.org/10.1007/s40263-018-0550-4 Abstract : The endocannabinoid retrograde signaling pathway is widely expressed in the central nervous system, where it plays major roles in regulating synaptic plasticity (excitatory and inhibitory) through long-term potentiation and long-term depression. The endocannabinoid system (ECS) components-cannabinoid receptors, endocannabinoids and synthesis/degradation enzymes-are expressed and are functional from early developmental stages and throughout adolescent cortical development, regulating progenitor cell fate, neural [...]

Taffe Committee on the Neurobiology of Addictive Disorders, The Scripps Research Institute, La Jolla, CA, USA British Journal of Pharmacology, 2013, 170, 1365–1373 BACKGROUND AND PURPOSE Recent human studies suggest that recreational cannabis strains that are relatively high in cannabidiol (CBD) content produce less cognitive impairment than do strains with negligible CBD and similar D9tetrahydrocannabinol (THC) content. Self-selection in such studies means it is impossible to rule out additional variables which may determine both cannabis strain selection and basal cognitive performance level. Controlled laboratory studies can [...]

DOI : 10.1523/JNEUROSCI.2946-14.2015 Abstract : Recent research has suggested that marijuana use is associated with volumetric and shape differences in subcortical structures, including the nucleus accumbens and amygdala, in a dose-dependent fashion. Replication of such results in well controlled [...]

Abstract : In spite of new drugs, lung cancer is associated with a very poor prognosis. While targeted therapies are improving outcomes, it is not uncommon for many patients to have only a partial response, and relapse during follow-up. Thus, new drugs or reevaluation of existing therapies used to treat other non-malignant diseases (drug repurposing) are still needed. While this research both in vitro and in vivo is being carried [...]
