Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to GABA-A receptors, enhancing GABA effects and increasing chloride ion conductance, leading to neuronal hyperpolarization and inhibition of seizure activity.
Binds to benzodiazepine site on GABA-A receptors, enhancing chloride ion conductance and neuronal hyperpolarization.
2.5 mg to 20 mg rectally, as a single dose for acute seizure clusters; may repeat once after 4-12 hours if needed. Maximum: 20 mg per treatment episode.
0.5 mg orally twice daily, titrated weekly by 0.5 mg/day to a maximum of 4 mg/day

Terminal elimination half-life: 20-50 hours in adults; prolonged in elderly and patients with hepatic impairment (up to 100 hours).
Terminal elimination half-life is 15–20 hours in adults; prolonged in elderly and hepatic impairment (up to 40 hours).
Primarily renal (urinary) as glucuronide conjugates and unchanged drug; <2% excreted unchanged in feces.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine. Metabolites are excreted renally (approx. 70%) and fecal/biliary (approx. 30%).
