Pharmacology
Rufinamide is an antiepileptic triazole derivative whose principal mechanism of action is modulation of sodium channel activity, specifically prolonging the inactive state of the channel to limit sustained repetitive neuronal firing.
Clobazam is a 1,5-benzodiazepine whose exact mechanism is not fully understood but is thought to involve potentiation of GABAergic neurotransmission through binding at the benzodiazepine site of the GABA-A receptor.
