Monotherapy has been promoted as the ideal in epilepsy treatment because of reduced side effects, absence of drug interactions, better compliance, lower cost and, in many cases, improved seizure control compared to polytherapy. The question of monotherapy vs. polytherapy has assumed increasing importance with the availability of multiple new antiepileptic drugs (AEDs), initially tested as add-on agents. The new drugs clobazam, lamotrigine, vigabatrin, gabapentin and topiramate, have also been shown to be effective as monotherapy. These data bring up the possibility of using them as first-line agents. However, a high percentage of patients with resistant epilepsy are treated with polytherapy, which probably benefits only a minority of them. The availability of multiple drugs with different mechanisms of action favours the possibility of "rational polytherapy", taking advantage of possible synergism, a yet unproven concept. This article reviews the theoretical advantages of monotherapy and monotherapy with traditional and newer AEDs.
