Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to benzodiazepine site on GABA-A receptor, potentiating GABAergic inhibition and increasing chloride ion conductance.
Benzodiazepine that enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
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.
0.5-2 mg orally every 6-8 hours as needed. Maximum 4 mg/day.

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.
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in elderly (15-20 hours) and patients with hepatic impairment (up to 30-40 hours).
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.
Renal excretion of glucuronide conjugates; <1% unchanged drug excreted renally. Fecal elimination accounts for approximately 10% of administered dose.
