Pharmacology
Topiramate is a sulfamate-substituted monosaccharide anticonvulsant whose precise mechanism is unknown but is believed to involve blockade of voltage-dependent sodium channels, augmentation of GABA-A receptor activity, antagonism of AMPA/kainate glutamate receptors, and inhibition of carbonic anhydrase isozymes II and IV.
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.
