For neonatal seizures, controlling brain excitability with a long-acting anticonvulsant is the typical approach, and phenobarbital fits that role best. It provides reliable seizure suppression in newborns when given as a loading dose (around 20 mg/kg IV) with subsequent maintenance dosing to prevent recurrence. Neonates often have immature liver enzymes and unique brain physiology, so a drug with proven efficacy and predictable CNS effects like phenobarbital is preferred. It also has a long history of use in this age group, making its safety and dosing more familiar to clinicians.

Other options are less ideal in neonates. Diazepam can cause prolonged sedation and respiratory depression, making it less favorable as a first-line choice. Phenytoin can be effective but has more potential for hypotension and less reliable seizure control in newborns. Valproate is generally avoided in neonates due to hepatotoxicity risk and limited safety data in this age, making it unsuitable as a standard initial therapy.
