The primary objective of this study is to determine the pharmacokinetic profile of a 50 mg/kg loading dose of intravenous levetiracetam (LEV) in term and late preterm infants with seizures. Secondary objectives are to evaluate the safety and efficacy of a 50 mg/kg loading dose of levetiracetam in term and preterm infants with seizures, and to obtain data on steady state drug levels of levetiracetam in neonates.

| levetiracetam | Drug | 50 mg/kg single loading dose of IV levetiracetam |
| Measure | Description | Time Frame |
|---|---|---|
| Pharmacokinetic Profile | 3 levels for levetiracetam and its metabolite L057 will be drawn: at 5-20 minutes after the dose, 1-2 hours after the dose, and 6-10 hours after the dose. In infants who remain on maintenance doses of the medication, a steady state level will be drawn 4-7 days after the loading dose. Outcome reported is clearance. The median maximum clearance rate was measured in each participant and determined by evaluating the levels of levetiracetam at each time point using MW Pharm. | 5-20 minutes after the dose, 1-2 hours after the dose, 6-10 hours after the dose, and possibly 4-7 days after loading dose (if infants remained on maintenance doses) |
