KEPPRA vs NEURAMATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Levetiracetam binds to synaptic vesicle protein 2A (SV2A), modulating neurotransmitter release and reducing neuronal hyperexcitability. It also inhibits high-voltage N-type calcium channels and reduces GABAergic and glycinergic inhibition.
NEURAMATE is a brand name for pentobarbital, a barbiturate that enhances GABA-A receptor activity by binding to the barbiturate binding site, increasing the duration of chloride ion channel opening, thereby producing CNS depression.
500 mg orally twice daily, titrated up to 1500 mg twice daily as tolerated.
250 mg orally three times daily; maximum 1000 mg/day.
