Prospective Open-Label, Single-Arm, Multicenter, Safety, Tolerability, and Pharmacokinetic Studies of Intravenous Levetiracetam in Children With Epilepsy

Abstract

Levetiracetam given via intravenous administration has been shown to be an effective alternative in adults with epilepsy when oral administration is not feasible. This study was a prospective single-arm, multicenter study to assess tolerability, safety, and pharmacokinetics of intravenous levetiracetam in children with epilepsy. Children with epilepsy ages 1 month to 16 years requiring intravenous levetiracetam were enrolled. Assessments included vital signs, electrocardiogram, hematology, chemistry, plasma concentrations of antiepileptic medications, weight, physical/neurological examinations, and pharmacokinetics. A total of 52 patients were enrolled. Mild to moderate treatment-emergent adverse events occurred in 63%, the most frequent being pyrexia and dry mouth. Most other treatment-emergent adverse events were considered unrelated to intravenous levetiracetam administration. Therefore, intravenous levetiracetam in the acute setting was overall well tolerated in children 1 month to 16 years.
