Comparative efficacy of combination drug therapy in refractory epilepsy

Abstract

These results suggest that at least one AED regimen provides significantly better efficacy in refractory convulsive epilepsy, and that AEDs should be used no more than 2 at a time. Limitations of the study include its retrospective design, lack of randomization, and small sample sizes for some drug combinations. Future prospective trials are needed in this challenging clinical population.
