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.
Benzodiazepine that enhances GABA-A receptor activity, increasing chloride ion conductance and causing neuronal hyperpolarization.
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.
IV: Initial 1-2.5 mg; titrate by 0.5-1 mg every 2-3 min; usual total 2.5-5 mg for sedation. IM: 0.07-0.08 mg/kg (max 5 mg) once. Oral: 7.5-15 mg once (preoperative).

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: 1.8–2.5 hours in healthy adults; prolonged in elderly (up to 6 hours), obesity (up to 8 hours), hepatic cirrhosis (up to 20 hours), and critically ill patients.
Renal: approximately 50-60% as metabolites (mainly conjugated forms), with less than 1% unchanged. Fecal: minor, about 10%. Biliary excretion contributes to enterohepatic circulation.
Renal: ~1% unchanged; Hepatic metabolism to glucuronide conjugates and 1-hydroxymidazolam, with subsequent renal elimination of metabolites. Fecal excretion is minimal (<2%).
