Background: Neonatal seizures represent the most frequent presenting sign of any neurological abnormality secondary to various etiologies in the neonatal period. Phenobarbitone (PB) has been used as first-line anti-epileptic drug in the treatment of seizures but concerns have been raised regarding its neuro-apoptotic effects over the developing brain. Levetiracetam (LEV) is a newer anti-epileptic drug with neuroprotective property and has been used in adults and pediatric patient but its use in neonates have very limited experience. Recently many neonatal studies have sought the role of LEV in the management of neonatal seizures.
Aims and objective: To evaluate the efficacy of Levetiracetam in the management of neonatal seizures.
Search methods: The literature search was done for this systematic review by searching the Cochrane Central Register of Controlled Trials (CENTRAL), and other various electronic databases including PubMed and various sites for ongoing trials and abstracts of conferences.
Results: Two eligible studies were analyzed that fulfilled the inclusion criteria of the systematic review. Fifteen studies were excluded due to the non-fulfillment of inclusion criteria. The primary outcome of both studies was to see the efficiency of LEV in controlling neonatal seizures when compared to PB. Better seizure control after a single loading dose of LEV was seen. Rates of seizure cessation at 24 h was also better in the LEV arm. Neonatal seizures secondary to hypoxic-ischemic encephalopathy (HIE) and receiving therapeutic hypothermia were better controlled with LEV. The side effect of LEV was significantly less when compared to PB.
Conclusion: Levetiracetam has shown to have promising anti-epileptic properties for the management of neonatal seizure with better efficacy and less or no side effects. There is a need to conduct more randomized controlled trials seeking the role of LEV in the acute management of neonatal seizures and also for assessing its neuroprotective role and neurodevelopmental outcome in these neonates.
