title: The pharmacologic basis of antiepileptic drug action.
abstract: The development of medications used in the treatment of epilepsy has accelerated over the past decade, and has benefited from a parallel growth in our knowledge of the basic mechanisms underlying neuronal excitability and synchronization. This understanding of the pharmacologic basis of antiepileptic drug (AED) action has, in large part, arisen from recent advances in cellular and molecular biology, coupled with avenues of drug discovery that have departed somewhat from the largely empiric approaches of the past. Physicians now have available to them an ever-growing armentarium of AEDs, necessitating a firmer appreciation of their mechanisms of action if more rational approaches toward both clinical application and research are to be adopted. An important example in this regard is the concept of rational polypharmacy for patients with epilepsy who are refractory to monotherapy. This review summarizes our current understanding of the molecular targets of clinically significant AEDs, comparing and contrasting their differing mechanisms of action.
