INTRODUCTION: Treatment of status epilepticus (SE) has not changed in the last few decades, benzodiazepines plus phenytoin being the most common first line treatment. Intravenous levetiracetam (ivLEV) is a new antiepileptic drug with interesting properties for SE. MATERIAL AND METHODS: Efficacy and effectiveness of ivLEV in SE were assessed in an observational, multicentric and retrospective study. Efficacy was defined as cessation of seizures in the 24h subsequent to starting ivLEV, with no need of any further antiepileptic drug. All patients were treated following the standard protocol (benzodiazepines plus phenytoin or valproate). ivLEV was used as add-on therapy, except in those cases with contraindication for the standard protocol, when it was administered earlier. RESULTS: 40 patients were included, 57% men, with a mean age of 63 years. The most common type of SE was partial convulsive (90%). ivLEV was effective in approximately half of the patients (57.5%), in a mean time of 14.4h. ivLEV was used as add-on treatment in 26 patients (after benzodiazepines plus phenytoin, valproate or both) with an efficacy of 46.1%, and as early treatment (pretreatment with benzodiazepines or nothing) in 14 patients with an efficacy of 78.5% (p 0.048). Adverse events were observed in 15% of patients. CONCLUSIONS: ivLEV was an effective antiepileptic drug for SE, but its efficacy depends on the timing of its administration, being more effective when used as early treatment, and less effective as add-on treatment.
