  • Patent number: 11419829
    Abstract: The present invention relates to the use of cannabidiol (CBD) in combination with an agonist of 5-HT2B receptors. Such a combination provides protection against the adverse effects caused by agonists of 5-HT2B receptors. The invention further relates to the use of CBD in combination5 with an amphetamine or amphetamine derivative in the treatment of epilepsy. In one embodiment the CBD is used in combination with the amphetamine derivative fenfluramine to produce a significant reduction in seizures. Preferably the CBD used is in the form of a highly purified extract of cannabis such that the CBD is present at greater than 98% of the total extract (w/w) and the other components of the extract are characterised. In particular the cannabinoid10 tetrahydrocannabinol (THC) has been substantially removed, to a level of not more than 0.15% (w/w) and the propyl analogue of CBD, cannabidivarin, (CBDV) is present in amounts of up to 1%. Alternatively, the CBD may be a synthetically produced CBD.

  • Publication number: 20220168266
    Abstract: Cannabidiol (CBD) is a cannabinoid designated chemically as 2-[(IR,6R)-3-Methyl-6-(1-methylethenyl)-2-cyclohexen-1-yl]-5-pentyl-1,3-benzenediol. Its empirical formula is C21H30O2 and its molecular weight is 314.46. CBD is a cannabinoid that naturally occurs in the Cannabis sativa L. plant. CBD is a white to pale yellow crystalline solid which is insoluble in water and soluble in organic solvents. The present invention encompasses the surprising recognition that certain CBD preparations which are prepared from a botanical origin are more effective in treating diseases or disorders than preparations of CBD which are synthetic or purified to the extent no other impurities in the form of other cannabinoids are present. Prior CBD compositions have been prepared such that no psychoactive components, e.g., tetrahydrocannabinol (THC), remain in the final CBD preparation. Surprisingly, the absence of such minor impurities reduces the efficacy of CBD treatment.

  • Publication number: 20220016048
    Abstract: The present invention relates to a cannabidiol (CBD) type cannabinoid compound for use as a medicament. The CBD-type cannabinoid, cannabidiol-C4 (CBD-C4), is a naturally occurring cannabinoid that can be found in minor quantities in the cannabis plant. Furthermore, the cannabinoid can be produced by synthetic means. Disclosed herein are data which demonstrate the efficacy of CBD-C4 in models of disease. In addition, a method for the production of CBD-C4 is described.

  • Publication number: 20210077455
    Abstract: The present invention relates to the use of cannabinoids in the treatment of a neurodegenerative disease or disorder. In particular the cannabinoids cannabidiolic acid (CBDA) and cannabidivarin (CBDV) were able to produce neuroprotective effects in a mouse model of neurodegenerative disease. In particular these effects were associated with the symptoms associated with amyotrophic lateral sclerosis (ALS). Furthermore, the combination of the cannabinoid tetrahydrocannabinol (THC) with the drug olexisome provided a synergistic disease modifying effect in a mouse model of neurodegenerative disease. In particular these effects were associated with the symptoms associated with ALS.

  • Publication number: 20200206153
    Abstract: The present invention relates to the use of cannabidiol (CBD) for the treatment of tumours associated with Tuberous Sclerosis Complex (TSC). In particular the CBD was able to decrease the number and size of marker cells, pS6, in a zebrafish model of TSC. This is5 suggestive of a disease modifying effect whereby treatment with CBD could result in the reduction or prevention of the benign tumours that occur in TSC patients. Preferably the CBD used is in the form of a highly purified extract of cannabis such that the CBD is present at greater than 98% of the total extract (w/w) and the other components of the extract are characterised. In particular the cannabinoid tetrahydrocannabinol (THC) has been substantially 10 removed, to a level of not more than 0.15% (w/w) and the propyl analogue of CBD, cannabidivarin, (CBDV) is present in amounts of up to 1%. Alternatively, the CBD may be a synthetically produced CBD. In use the CBD is given concomitantly with one or more other drugs used in the treatment of TSC.
