Cannabidiol has a unique effect on global brain activity: a pharmacological, functional MRI study in awake mice Aymen H. Sadaka, Ana G. Ozuna1, Richard J. Ortiz, Praveen Kulkarni, Clare T. Johnson, Heather B. Bradshaw, Bruce S. Cushing, Ai‑Ling Li, Andrea G. Hohmann and Craig F. Ferris Journal of Translationnal Medicine, 2021, 19, 220, 1-16. Doi : 10.1186/s12967-021-02891-6 Abstract Background : The phytocannabinoid cannabidiol (CBD) exhibits anxiolytic activity and has been promoted as a potential treatment for post-traumatic stress disorders. How does CBD interact with the brain to alter behavior? We hypothesized that CBD would produce a dose-dependent reduction in brain activity and functional coupling in [...]

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 [...]

However, few data have been provided to clinicians about the pharmacokinetic drug-drug interactions of cannabinoids with other concomitant administered medications. Therefore, the aim of this brief review is to assess the interactions between [...]
Lire la suiteAn Analysis of Over-the-Counter Cannabidiol Products in the United Kingdom Jonathan Paul Liebling, Nicholas James Clarkson, Blair William Gibbs, Andrew Stephen Yates, and Saoirse Elizabeth O’Sullivan Cannabis and Cannabinoid Research, 2020, 1-7. DOI: 10.1089/can.2019.0078 Abstract Introduction : Over-the-counter cannabidiol (CBD) products have seen unprecedented recent growth in the United Kingdom. However, analysis of these predominantly unregulated products from other countries tells us that they are often mislabeled or contain unlabeled and potentially dangerous chemicals. Thus, the aim of the present study was to analyze CBD oils available in the United Kingdom. Materials and Methods: Phytocannabinoids, residual solvent, and heavy metals were measured blinded in 29 [...]
