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; [...]

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 [...]

Frontiers in Pharmacology, 2019, 9, 1521. doi : 10.3389/fphar.2018.01521, PMID : 30687090 Objective: Children with autism spectrum disorder (ASD) commonly exhibit comorbid symptoms such as aggression, hyperactivity and anxiety. Several studies are being conducted worldwide on cannabidiol use in ASD; however, these studies are still ongoing, and data on the effects of its use is very limited. In this study we aimed to report the experience of parents who administer, under supervision, oral [...]

Alternatives to opioids for the treatment of pain are necessary to address this issue. Cannabis can be an effective treatment for pain, greatly reduces the chance of dependence, and eliminates the risk of fatal overdose compared to opioid-based medications. Medical cannabis patients report that cannabis is just as effective, if not more, than opioid-based medications for pain. Materials and Methods: The current study examined the [...]

Apart from updating the literature, this article focuses on clinical studies and CBD potential interactions with other drugs. Results: In general, the often described favorable safety profile of CBD in humans was confirmed and extended by the reviewed research. The majority of studies were performed for treatment of epilepsy [...]

Lire la suiteFrançais, encore un effort pour le cannabis thérapeutique ! Dr Bertrand Lebeau, texte pour Michka, mai 2008. La redécouverte des propriétés thérapeutiques du cannabis est récente dans les pays occidentaux mais, désormais, les recherches se multiplient et les cadres légaux se transforment.
