Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that potentiates GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
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.
2-3 mg orally divided 2-3 times daily; up to 10 mg/day. IV: 2 mg slow IV push, may repeat in 1-2 hours; max 10 mg/day. IM: 0.05 mg/kg (max 4 mg) 2-4 hours before procedure.
1-2 mg orally at bedtime.

Terminal elimination half-life is 12–18 hours (mean ~14 h). In elderly, hepatic impairment, or obesity, half-life may be prolonged up to 30 hours.
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: 10-24 hours (mean ~17 hours); prolonged in elderly and hepatic impairment.
Renal: lorazepam is primarily excreted as inactive glucuronide conjugates; <1% is excreted unchanged. Total: ~95% excreted in urine, ~5% in feces.
Renal: ~90% as metabolites, <1% unchanged. Fecal: small amount, ~10%.
