Insights
Intravenous levetiracetam is safe and well-tolerated in children aged 6 months to 15 years. This study confirms a 50 mg/kg dose as an appropriate loading dose for pediatric epilepsy treatment.
Area of Science:
- Pediatric Neurology
- Clinical Pharmacology
- Epilepsy Treatment
Background:
- Intravenous levetiracetam is FDA-approved for adults with epilepsy.
- Limited data exists on its use in pediatric populations.
Purpose of the Study:
- To establish the safety, tolerability, and dosage of intravenous levetiracetam in children.
- To evaluate levetiracetam blood levels and adverse reactions in pediatric patients.
Main Methods:
- Prospective study of 30 children (6 months to <15 years).
- Administered a single intravenous dose of levetiracetam (50 mg/kg, max 2500 mg).
- Measured levetiracetam blood levels 10 minutes post-infusion.
Main Results:
- Mean age of participants was 6.3 years.
- Mean levetiracetam level was 83.3 microg/mL.
- No serious adverse reactions; minor reactions included sleepiness and fatigue.
- Apparent decrease in seizure frequency observed.
Conclusions:
- The 50 mg/kg intravenous levetiracetam dose is safe and well-tolerated in children.
- This dose is an appropriate loading dose for pediatric epilepsy.
- Further research may explore long-term efficacy and safety.
Abstract:
In 2006, intravenous levetiracetam received US Food and Drug Administration (FDA) approval for adjunctive treatment of partial onset seizures in adults with epilepsy, 16 years or older. We have established the safety, tolerability, and dosage of intravenous levetiracetam in children. This prospective study included 30 children (6 months to <15 years of age). Patients were administered a single dose of intravenous levetiracetam (50 mg/kg, maximal dose 2500 mg) over 15 minutes. A blood level of levetiracetam was performed 10 minutes after the infusion. The treated children's average age was 6.3 years (range 0.5-14.8 years). The mean levetiracetam level was 83.3 microg/mL (range 47-128 microg/mL). There were no serious adverse reactions. Minor reactions included sleepiness, fatigue, and restlessness. An apparent decrease in seizure frequency across all seizure types was noted. The dose of 50 mg/kg was well tolerated by the patients and is a safe, appropriate loading dose.
