Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that potentiates GABA-A receptor activity by binding to the benzodiazepine site, increasing chloride ion conductance and neuronal inhibition.
Binds to benzodiazepine site on GABA-A receptor, potentiating GABAergic inhibition and increasing chloride ion conductance.
2 to 10 mg orally 2 to 4 times daily, as needed for anxiety or muscle spasm; 10 mg orally before procedures for sedation. Maximum 40 mg/day.
5-25 mg orally 3-4 times daily; or 50-100 mg intramuscularly or intravenously initially, then 25-50 mg 3-4 times daily as needed.

Terminal elimination half-life is 20–50 hours (mean ~30 hours) in adults, with significant interindividual variability; prolonged in elderly, hepatic impairment, and neonates (up to 100 hours).
Terminal elimination half-life of chlordiazepoxide is 24-48 hours; active metabolite desmethyldiazepam has half-life of 36-200 hours; with repeated dosing, effective half-life extends due to accumulation of active metabolites.
Renal excretion of metabolites (primarily glucuronide conjugates) accounts for ~70% of elimination; fecal excretion accounts for ~10%; unchanged drug in urine is <1%.
Renal excretion of unchanged drug and metabolites (primarily glucuronide conjugates of chlordiazepoxide and demoxepam, <2% unchanged); approximately 60-70% of a dose appears in urine as metabolites, with 4-9% in feces via biliary elimination.
