Intravenous levetiracetam versus intravenous phenytoin as second Line treatment in pediatric convulsive status epilepticus- open label randomized controlled trial.

Background: Benzodiazepines (BZDs) are recommended as the initial therapy of choice in status epilepticus (SE). The age-old second-line treatment for BZD refractory convulsive SE is intravenous phenytoin (PHT) based predominantly on nonrandomized clinical trial data. We did this study to compare the efficacy and safety of intravenous levetiracetam (LEV) and PHT as second-line antiseizure medication (ASM) for children with SE.

Methodology: A prospective, randomized controlled, open-label study was conducted in children 3 months to 15 years of age with SE in Pediatric Emergency. A total of 41 children were randomly allocated to either group 1 (Levetiracetam) or group 2 (Phenytoin) on the basis of computer-generated randomization. Children who were already on antiseizure medications, either LEV or PHT, or receiving these drugs outside for SE were excluded. Data analysis was done by SPSS V25.

Results: The most common age group presenting with SE was 12 months to 5 years. Clinical cessation of seizure 5 minutes after the completion of drugs was 85% (17/20) in Levetiracetam group and 90.5% (19/21) in Phenytoin group. Recurrence of seizure within 24 hours was noted in 35% (7/20) in Levetiracetam group and 38.1% (8/21) in Phenytoin group. There was no statistically significant difference noted in both the groups in terms of seizure cessation, adverse events, and recurrence.

Conclusion: The efficacy and safety of LEV were found to be comparable to those of PHT in controlling seizure as second-line ASM in SE.
