Epidiolex (Cannabidiol): A New Hope for Patients With Dravet or Lennox-Gastaut Syndromes.

 SAGE Journals

“OBJECTIVE: To review the efficacy, safety, pharmacology and pharmacokinetics of pure, plant-derived cannabidiol (CBD; Epidiolex) in the treatment of Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS).

DATA SYNTHESIS: Pure, plant-based CBD is a pharmaceutical grade extract that exhibits clinically significant antiseizure properties, with a hypothesized multimodal mechanism of action. In the GWPCARE trial series, CBD displayed superior efficacy in reducing key seizure frequencies (convulsive seizures in DS; drop seizures in LGS) by 17% to 23% compared with placebo as adjunctive therapy to standard antiepileptic drugs in patients 2 years of age and older. Common adverse effects were somnolence, diarrhea, and elevated hepatic transaminases. Noteworthy drug-drug interactions included clobazam, valproates, and significant inducers/inhibitors of CYP2C19 and 3A4 enzymes.

Relevance to Patient Care and Clinical Practice: A discussion regarding CBD dosing, administration, adverse effects, monitoring parameters, and interactions is provided to guide clinicians. CBD offers patients with DS and LGS a new treatment option for refractory seizures.

CONCLUSION:

This is the first cannabis-derived medication with approval from the US Food and Drug Administration. This CBD formulation significantly reduces seizures as an adjunct to standard antiepileptic therapies in patients ≥2 years old with DS and LGS and is well tolerated.”

“Why marijuana is headed for the mainstream. The credibility of cannabis as a source of a legitimate pharmaceutical ingredient in prescription medications took a major step forward in 2018 when the FDA approved Epidiolex (cannabidiol) for two types of severe seizures. Epidiolex was a stellar candidate for approval. It reduced convulsive seizures by about 40% and has a good safety profile.”  https://www.ncbi.nlm.nih.gov/pubmed/30620324
