Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to benzodiazepine site on GABA-A receptor, enhancing GABA-mediated chloride ion influx, leading to neuronal hyperpolarization and reduced excitability.
GABA-A receptor positive allosteric modulator; enhances inhibitory neurotransmission.
Oral: 5-25 mg 3-4 times daily, up to 100 mg/day in severe anxiety; IM/IV: 50-100 mg initially, then 25-50 mg 3-4 times daily.
0.25 mg intravenously over 2 minutes, may repeat once after 15 minutes if inadequate response; maximum total dose 0.5 mg.

Terminal elimination half-life: 6.6 to 28 hours (parent drug); clinically, duration of effect may be prolonged due to active metabolite nordazepam (half-life 30-100 hours), especially in elderly or hepatic impairment.
Terminal elimination half-life is approximately 2–4 hours in patients with normal renal function; may be prolonged up to 8–12 hours in severe renal impairment (CrCl <30 mL/min).
Renal: approximately 50-60% as metabolites (mainly conjugated forms), with less than 1% unchanged. Fecal: minor, about 10%. Biliary excretion contributes to enterohepatic circulation.
Primarily renal excretion of unchanged drug (approximately 85%) and glucuronide conjugates (approximately 10%); biliary/fecal excretion accounts for less than 5%.
