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.
SERAX (oxazepam) is a benzodiazepine that modulates GABA-A receptors, enhancing the inhibitory effect of GABA, leading to anxiolytic, sedative, and anticonvulsant effects.
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.
Oral: 5-10 mg twice daily; maximum 20 mg/day. Intravenous: 2-5 mg slow IV push, may repeat after 2 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.
Terminal elimination half-life is 8-15 hours (mean 12 hours) in adults; prolonged in renal impairment.
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.
Primarily renal (urinary) as unchanged drug (60-80%) and metabolites (20-40%); less than 5% fecal elimination.
