Abstract

Antiepileptic drugs GABAA receptor Glutamate receptors Refractory status epilepticus Seizures Topiramate
Refractory status epilepticus (RSE) occurs in patients with SE when they fail to respond to traditional medical therapy. Because there are very few case reports of topiramate (TPM) treatment of RSE in adult patients, we examined our experience with TPM with regard to its safety and efficacy in seizure termination in RSE in an adult patient population. We report a retrospective review of 35 adult patients with RSE who were treated with TPM in addition to other antiepileptic drugs (AEDs) between 2003 and 2010. After failure of initial treatments of benzodiazepines and weight-based intravenous loading doses of standard AEDs, TPM tablets were crushed and administered via nasogastric tube. Data were collected on age, gender, history of epilepsy, etiology of RSE, daily dose of TPM, co-therapeutic agents, treatment response, and disposition. Following initiation of TPM use and discontinuation of continuous intravenous anesthetics with no additional AEDs administered, cumulative cessation of RSE in patients was 4/35 (11%) at one day, 10/35 (29%) at two days, and 14/35 (40%) at three days. However, when including all patients and comparing the two patient groups in which RSE was or was not terminated within three days of initiating TPM as the last or not last AED given, there was no significant difference. Time to TPM response was not associated with the type of seizures, etiology of SE, or whether there was a history of epilepsy. There were no documented side effects or complications of therapy with TPM. This study provides support for the use of TPM as an adjunctive agent in the treatment of RSE.
