The invention relates to the use of cannabidiol (CBD), at a dose of greater than 300 mg/day, in combination with a standard anti-epileptic drug (SAED) which acts via sodium or calcium channels, for use in the treatment of epilepsy. The SAED is preferably one which •modities low-threshold or transient neuronal calcium currents, or •reduces high-frequency neuronal firing and sodium-dependent action potentials and enhances GABA effects. Preferred SAEDs are ethosuximide and valproate.

Use of the phytocannabinoid cannabidiol (CBD) in combination with a standard anti-epileptic drug (SAED) in the treatment of epilepsy

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 is 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 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. Such drugs may include rapamycin and/or everolimus.

Use of cannabidiol in the treatment of tuberous sclerosis complex

This invention relates to a pharmaceutical composition comprising or consisting essentially of the phytocannabinoids cannabidivarin (CBDV) and cannabidiol (CBD). The composition is particularly safe and efficacious for use in the treatment of neurological conditions, characterized by hyper-excitability of the central nervous system, convulsions or seizures such as occur in epilepsy. Preferably the CBDV and the CBD are present with at least one non-cannabinoid component of cannabis such as one or more terpenes or a terpene fraction. More particularly the composition further comprises one or more cannabichromene type compounds. Particularly cannabichromene propyl variant (CBCV) and/or cannabichromene (CBC). More particularly still the composition is absent or substantially absent of other cannabinoids, including in particular tetrahydrocannabinol (THC) and tetrahydrocannabivarin (THCV), which would normally be present in significant amounts in cannabis chemotypes bred to contain a significant amount of CBDV and/or CBD.

Pharmaceutical composition comprising the phytocannabinoids cannabidivarin (CBDV) and cannabidiol (CBD)

This invention relates to the use of the phytocannabinoid cannabidivarin (CBDV) and combinations of the phytocannabinoid CBDV with tetrahydrocannabivarin (THCV) and cannabidiol (CBD) in the treatment of epilepsy. The invention further relates to the use of the phytocannabinoid CBDV in combination with standard anti-epileptic drugs (SAEDs). Preferably the SAED is one of ethosuximide, valproate or phenobarbital.

Use of the phytocannabinoid cannabidivarin (CBDV) in the treatment of epilepsy

The present invention relates to the use of 7-hydroxy-cannabidol (7-OH-CBD) and/or 7-hydroxy-cannabidivarin (7-OH-CBDV) in the treatment of epilepsy. Preferably the cannabinoid metabolites are isolated from plants to produce a highly purified extract or can be reproduced synthetically.

7-OH-cannabidiol (7-OH-CBD) and/or 7-OH-cannabidivarin (7-OH-CBDV) for use in the treatment of epilepsy

This invention relates to a pharmaceutical composition comprising or consisting essentially of the phytocannabinoids cannabidivarin (CBDV) and cannabidiol (CBD). The composition is particularly safe and efficacious for use in the treatment of neurological conditions, characterized by hyper-excitability of the central nervous system, convulsions or seizures such as occur in epilepsy. Preferably the CBDV and the CBD are present with at least one non-cannabinoid component ofsuch as one or more terpenes or a terpene fraction. More particularly the composition further comprises one or more cannabichromene type compounds. Particularly cannabichromene propyl variant (CBCV) and/or cannabichromene (CBC). More particularly still the composition is absent or substantially absent of other cannabinoids, including in particular tetrahydrocannabinol (THC) and tetrahydrocannabivarin (THCV), which would normally be present in significant amounts inchemotypes bred to contain a significant amount of CBDV and/or CBD.

This invention relates to the use of one or more cannabinoids in the treatment of epilepsy and more particularly to the use of one or a combination of cannabinoids in the treatment of generalized or partial seizure. In one embodiment it relates to the use of the cannabinoid THCV, as a pure or isolated compound, or as a plant extract in which significant amounts of any THC naturally present has been selectively removed. In another embodiment the phytocannabinoid is CBD.
