  • Patent number: 10709671
    Abstract: The present invention relates to the use of cannabidiol (CBD) in the treatment of focal seizures. In one embodiment the patients suffering from focal seizures are children and young adults. CBD appears particularly effective in reducing focal seizures in patients suffering with etiologies that include: Lennox-Gastaut Syndrome; Tuberous Sclerosis Complex; Dravet Syndrome; CDKL5; Neuronal ceroid lipofuscinoses (NCL); febrile infection related epilepsy syndrome (FIRES); Aicardi syndrome and brain abnormalities in comparison to other seizure types.

  • Patent number: 10583096
    Abstract: The present invention relates to the use of cannabidiol (CBD) in the treatment of Sturge Weber syndrome. CBD appears particularly effective in reducing all types of seizures and non-seizure symptoms in patients suffering with Sturge Weber syndrome. 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 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: 20200022925
    Abstract: The present invention relates to the use of a combination of two different cannabinoids in the treatment of leukaemia. The combination of CBD with THC appears to be particularly effective in reducing cell number in this disease. Preferably the cannabinoids are used in the form of an extract of cannabis such that many of the naturally occurring compounds are co-extracted with the THC or CBD. Alternatively, the cannabinoids are present in the form of a highly purified extract of cannabis, wherein the CBD or THC are present at greater than 98% of the total extract (w/w) and the other components of the extract are characterised. Alternatively, the CBD and THC may be synthetically produced. A specific ratio of CBD and THC such as 10:1 to 1:10 (CBD:THC) or more preferably between 2:1 to 1:2 (CBD:THC) may be used.

  • Patent number: 10039724
    Abstract: The liver plays a key role in regulating total body energy homeostasis and its ability to do so is greatly affected by the occurrence of pathological conditions such as hepatosteatosis or non-alcoholic fatty liver disease (NAFLD), which contributes to hepatic insulin resistance and potentially end-stage liver disease-related mortality. Triglyceride accumulation in hepatocytes of steatotic livers results from the incorporation of plasma free fatty acids as well as de novo fat synthesis. The present invention relates to the use of 7-hydroxy-cannabidiol (7-OH-CBD) in the treatment of non-alcoholic fatty liver disease (NAFLD). Treatment of NAFLD involves lowering the triglyceride levels in a patient's blood stream.
