Pharmacology
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.
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.
