ESTAZOLAM vs MENRIUM 5-2
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.
Combination of chlordiazepoxide (benzodiazepine) potentiating GABA-A receptor activity, and clidinium (antimuscarinic) blocking muscarinic acetylcholine receptors.
1-2 mg orally at bedtime.
1 tablet orally every 6-8 hours as needed for anxiety, up to 4 tablets per day. Each tablet contains chlordiazepoxide 5 mg and clidinium bromide 2.5 mg.

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
Chlordiazepoxide: 5-30 hours (increases with age, hepatic impairment); Clidinium: 8-12 hours
Renal: ~90% as metabolites, <1% unchanged. Fecal: small amount, ~10%.
Chlordiazepoxide: 90-96% renal as metabolites, <5% unchanged; Clidinium: 70-80% fecal, 10-20% renal as metabolites
