Abstract

This study aimed to compare the efficacy and safety of intravenous Levetiracetam and Phenobarbitone in the treatment of seizures in preterm neonates. It was an open-labeled, parallel randomized controlled trial conducted in a tertiary Neonatal Intensive Care Unit, India. Total 48 preterm neonates (28-36+6weeks) with clinical seizures were randomized to receive either Levetiracetam (LEV; 40mg/kg, then 20mg/kg) or Phenobarbitone (PB; 15mg/kg, then 10mg/kg) intravenously as first loading dose in ratio 1:1; second loading was given for persistent seizure. Efficacy was denoted by cessation of clinical seizures with first or second doses of the allotted antiepileptic, and remaining seizure-free for the next 24h. The demographic characteristics of preterm neonates and seizure types were comparable between both groups. Clinical seizure was controlled in 19 (79%) neonates in LEV group and 17 (70%) neonates in PB group, RR 1.12 (95% CI: 0.80 to 1.55), p = 0.504. There was increased respiratory support in PB group 9 (38%) vs. 3 (13%) in LEV group, RR 3.0 (95% CI: 0.92 to 9.74), p = 0.06. Conclusion: Levetiracetam and Phenobarbitone were equally efficacious for clinical neonatal seizure control, but increased respiratory support was found with Phenobarbitone use. What is Known: •Preterm neonates are at higher risk of neonatal seizure and Phenobarbitone is commonly used as the first line antiepileptic drugs in treating them. What is New: •Levetiracetam found equally efficacious as Phenobarbitone for cessation of clinical seizures in preterm neonates, with less adverse effect.
