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.
Midazolam hydrochloride is a benzodiazepine that enhances the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA-A receptor, resulting in increased chloride ion conductance, neuronal hyperpolarization, and inhibition of neuronal transmission. This produces sedative, anxiolytic, amnestic, and anticonvulsant effects.
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.
2.5-10 mg IV bolus for induction; 0.05-0.2 mg/kg/h IV infusion for sedation. IM: 0.07-0.08 mg/kg (max 5 mg) 30-60 min pre-procedure.

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.
Terminal elimination half-life: 1.5-3 hours in healthy adults; prolonged in elderly (up to 6 hours), obesity, hepatic cirrhosis (up to 20 hours), and congestive heart failure.
Renal: lorazepam is primarily excreted as inactive glucuronide conjugates; <1% is excreted unchanged. Total: ~95% excreted in urine, ~5% in feces.
Renal excretion of metabolites (approximately 90% as glucuronide conjugates, with less than 1% unchanged drug) and biliary/fecal excretion (approximately 5-10%).
