Use of cannabinoids in the treatment of epilepsy
The present disclosure relates to the use of cannabidiol (CBD) for the reduction of total convulsive seizure frequency in the treatment of “treatment-resistant epilepsy” (TRE). In particular, the disclosure relates to the use of CBD of treating TRE when the TRE is Dravet syndrome; myoclonic absence seizures or febrile infection related epilepsy syndrome (FIRES). The disclosure further relates to the use of CBD in combination with one or more anti-epileptic drugs (AEDs).
1. A method of reducing convulsive seizure frequency in a patient with a treatment-resistant epilepsy, which is Dravet syndrome, comprising administering to the patient in need thereof cannabidiol (CBD), wherein the CBD has a purity of at least 98% (w/w) CBD and comprises not more than 0.15% (w/w) Δ9-tetrahydrocannabinol (THC); and wherein dose of the CBD is at least 15 mg/kg/day.
2. A method of reducing convulsive seizure frequency in a patient with a treatment-resistant epilepsy, which is Dravet syndrome, comprising administering to the patient in need thereof cannabidiol (CBD), wherein the CBD has a purity of at least 98% (w/w) CBD and comprises not more than 0.15% (w/w) Δ9-tetrahydrocannabinol (THC), wherein the dose of the CBD is at least 10 mg/kg/day.
3. The method of claim 2 , wherein the dose of the CBD is 10 mg/kg/day.
4. The method of claim 2 , wherein the dose of the CBD is 12 mg/kg/day.
5. The method of claim 2 , wherein the dose of the CBD is 14 mg/kg/day.
6. The method of claim 2 , wherein the dose of the CBD is 15 mg/kg/day.
7. The method of claim 2 , wherein the dose of the CBD is 16 mg/kg/day.
8. The method of claim 2 , wherein the dose of the CBD is 18 mg/kg/day.
9. The method of claim 2 , wherein the dose of the CBD is 20 mg/kg/day.
10. A method of treating convulsive seizures in a patient with a treatment-resistant epilepsy, which is Dravet syndrome, comprising administering to the patient in need thereof cannabidiol (CBD), wherein the CBD has a purity of at least 98% (w/w) CBD and comprises not more than 0.15% (w/w) Δ9-tetrahydrocannabinol (THC); and wherein dose of the CBD is at least 15 mg/kg/day.
11. A method of treating convulsive seizures in a patient with a treatment-resistant epilepsy, which is Dravet syndrome, comprising administering to the patient in need thereof cannabidiol (CBD), wherein the CBD has a purity of at least 98% (w/w) CBD and comprises not more than 0.15% (w/w) Δ9-tetrahydrocannabinol (THC), wherein the dose of the CBD is at least 10 mg/kg/day.
