Multicenter StudyDeterminants of success in the use of oral levetiracetam in status epilepticus.
The use of new antiepileptic drugs for treatment of status epilepticus (SE) has not been studied systematically, particularly with respect to response predictors, the possibility of a dose-response relationship, and the efficacy of administration through a nasogastric tube. We analyzed 23 patients with SE treated with levetiracetam (LEV). The median daily dose of LEV was 2000 mg (range: 750-9000 mg). ⋯ No demographic or etiological variable was predictive. Among 16 patients given LEV through a nasogastric tube, administration was successful in 5; blood levels in 2 nonresponders were within or above the range 5-30 microg/mL. These data suggest that LEV may be a useful alternative in SE if administered early, even in intubated patients, and that escalating the dosage beyond 3000 mg/day will unlikely provide additional benefit.
