Use of cannabinoids in the treatment of epilepsy
The present disclosure relates to the use of cannabidiol (CBD) for the treatment of atonic seizures. In particular the CBD appears particularly effective in reducing atonic seizures in patients suffering with etiologies that include: Lennox-Gastaut Syndrome; Tuberous Sclerosis Complex; Dravet Syndrome; Doose Syndrome; Aicardi syndrome; CDKL5 and Dup15q in comparison to other seizure types. The disclosure further relates to the use of CBD in combination with one or more anti-epileptic drugs (AEDs).
1. A method of treating a typical absence seizure in a patient in need thereof, comprising administering to the patient a pharmaceutical composition comprising a cannabidiol (CBD) drug substance, wherein the CBD drug substance comprises at least 98% w/w CBD; and
wherein the dose of CBD administered to the patient ranges from about 5 mg/kg/day to about 25 mg/kg/day.
2. The method of claim 1 , wherein the CBD drug substance comprises at least 98% w/w CBD and not more than 0.15% w/w CBDA.
3. The method of claim 1 , wherein the CBD drug substance comprises at least 98% w/w CBD and not more than 1.0% w/w CBDV.
4. The method of claim 1 , wherein the CBD drug substance comprises at least 98% w/w CBD and not more than 0.15% w/w Δ9THC.
5. The method of claim 1 , wherein the CBD drug substance comprises at least 98% w/w CBD and not more than 0.5% w/w CBD-C4.
6. The method of claim 1 , wherein the CBD drug substance comprises at least 98% w/w CBD, not more than 1.0% w/w CBDV, and not more than 0.15% w/w Δ9THC.
7. The method of claim 1 , wherein the CBD drug substance comprises at least 98% w/w CBD, not more than 1.0% w/w CBDV, not more than 0.15% w/w Δ9THC, and not more than 0.5% w/w CBD-C4.
8. The method of claim 1 , wherein the CBD drug substance comprises at least 98% w/w CBD, not more than 0.15% w/w CBDA, not more than 1.0% w/w CBDV, not more than 0.15% w/w Δ9THC, and not more than 0.5% w/w CBD-C4.
9. The method of claim 1 , wherein the administering reduces the number of typical absence seizures compared to baseline.
10. The method of claim 1 , wherein the administering reduces typical absence seizure frequency compared to baseline.
11. The method of claim 1 , wherein the administering reduces typical absence seizure frequency by at least 50% compared to the typical absence seizure frequency experienced during a baseline period before CBD was administered.
12. The method of claim 8 , wherein the administering reduces the number of typical absence seizures compared to baseline.
13. The method of claim 8 , wherein the administering reduces typical absence seizure frequency compared to baseline.
14. The method of claim 8 , wherein the administering reduces typical absence seizure frequency by at least 50% compared to the typical absence seizure frequency experienced during a baseline period before CBD was administered.
15. The method of claim 1 , wherein the dose of CBD is 10 mg/kg/day.
16. The method of claim 1 , wherein the dose of CBD is 20 mg/kg/day.
17. The method of claim 15 , wherein the administering reduces the number of typical absence seizures compared to baseline.
18. The method of claim 15 , wherein the administering reduces typical absence seizure frequency compared to baseline.
19. The method of claim 15 , wherein the administering reduces typical absence seizure frequency by at least 50% compared to the typical absence seizure frequency experienced during a baseline period before CBD was administered.
20. The method of claim 16 , wherein the administering reduces typical absence seizures compared to baseline.
21. The method of claim 16 , wherein the administering reduces typical absence seizure frequency compared to baseline.
22. The method of claim 16 , wherein the administering reduces typical absence seizure frequency by at least 50% compared to the typical absence seizure frequency experienced during a baseline period before CBD was administered.
23. The method of claim 1 , wherein the dose of CBD administered to the patient ranges from about 10 mg/kg/day to about 20 mg/kg/day.
24. The method of claim 23 , wherein the administering reduces the number of typical absence seizures compared to baseline.
25. The method of claim 23 , wherein the administering reduces typical absence seizure frequency compared to baseline.
26. The method of claim 23 , wherein the administering reduces typical absence seizure frequency by at least 50% compared to the typical absence seizure frequency experienced during a baseline period before CBD was administered.
