Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine; enhances GABA-A receptor activity by binding to benzodiazepine site, increasing chloride ion influx and neuronal hyperpolarization.
Benzodiazepine that enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal inhibition.
7.5 mg to 15 mg orally 2 to 4 times daily; maximum dose 90 mg/day.
Oral: 11.25-22.5 mg once daily (sustained-release formulation).

Terminal elimination half-life of the active metabolite desmethyldiazepam is 30-200 hours (mean ~100 hours); parent drug clorazepate is rapidly hydrolyzed and has negligible half-life. Accumulation occurs with repeated dosing, leading to delayed peak effects and prolonged sedation.
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.
Primarily renal (80-90% as conjugated metabolites, including oxazepam and desmethyldiazepam); biliary/fecal excretion accounts for <10%.
Renal excretion of conjugated metabolites, with less than 1% unchanged drug; approximately 30% excreted in feces via biliary elimination.
