ESTAZOLAM vs LIBRIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that binds to GABA-A receptors at the alpha-1 subunit, enhancing the effect of GABA by increasing chloride ion conductance, leading to neuronal hyperpolarization and CNS depression.
Binds to benzodiazepine site on GABA-A receptor, potentiating GABAergic inhibition and increasing chloride ion conductance.
1-2 mg orally at bedtime.
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: 10-24 hours (mean ~17 hours); prolonged in elderly and hepatic impairment.
Clinical Note
moderateEstazolam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Estazolam is combined with Fluticasone propionate."
Clinical Note
moderateEstazolam + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Estazolam."
Clinical Note
moderateEstazolam + Erythromycin
"The serum concentration of Erythromycin can be increased when it is combined with Estazolam."
Clinical Note
moderateEstazolam + Cyclosporine
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: ~90% as metabolites, <1% unchanged. Fecal: small amount, ~10%.
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.
