Pharmacology

Cannabidiol is a phytocannabinoid antiepileptic; its precise mechanisms of anticonvulsant action in humans are unknown and do not appear to involve interaction with cannabinoid receptors.

Clobazam is a 1,5-benzodiazepine whose mechanism is thought to involve potentiation of GABAergic neurotransmission through binding at the benzodiazepine site of the GABA-A receptor; it is extensively metabolized to N-desmethylclobazam, an active metabolite with approximately 1/5 the activity of the parent compound.
