Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that enhances GABA-A receptor activity by binding to the benzodiazepine site, increasing chloride ion conductance and neuronal inhibition.
Benzodiazepine that enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal inhibition.
Initial: 10 mg PO TID; maintenance: 20-40 mg/day PO in divided doses; max: 120 mg/day.
Oral: 11.25-22.5 mg once daily (sustained-release formulation).

30–100 hours (mean ~50 h); prolonged in elderly and hepatic impairment; steady-state achieved in 7–10 days.
Terminal elimination half-life of nordazepam (active metabolite) is 30–100 hours (mean 50 hours); clorazepate itself has a short half-life (~2 hours) due to rapid conversion.
Renal: ~80% as glucuronide and oxidized metabolites; fecal: ~20% via biliary excretion.
Renal excretion of conjugated metabolites, with less than 1% unchanged drug; approximately 30% excreted in feces via biliary elimination.
