Combination of antiseizure medications phenobarbital, ketamine, and midazolam reduces soman‐induced epileptogenesis and brain pathology in rats

Abstract

Benzodiazepine efficacy is drastically reduced with time after seizure onset and inversely related to seizure duration. To overcome pharmacoresistance in severe benzodiazepine-refractory cholinergic-induced SE, simultaneous drug combination to include drugs that target both the loss of inhibition (eg, midazolam, phenobarbital) and the increased excitatory response (eg, ketamine) is more effective than benzodiazepine or barbiturate monotherapy.
