Phenobarbital (PB) has been traditionally used as the first-line treatment for neonatal seizures. More recently, levetiracetam (LEV) has been increasingly used as a promising newer antiepileptic medication for treatment of seizures in neonates. Objectives .

Websystem and is released at up to 40% of all synapses in the brain. GABA is synthesised from glutamate by the action of the enzyme glutamic acid decarboxylase. Following release from GABAergic nerve terminals, it acts on both GABAA and GABAB receptors, with a net hyperpolarising or inhibitory effect. The GABAA receptor is a ligand-gated ion channel,
WebThe elimination follows first-order kinetics. Pharmacokinetic interactions with Phenobarbital are seen frequently.
