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; enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
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.
0.5 mg to 2 mg orally twice daily for anxiety; 0.5 mg to 1 mg orally three times daily for panic disorder. Maximum dose: 4 mg/day for panic disorder.

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 half-life 30-40 hours (range 19-60 h) in adults; accumulation occurs with repeated dosing, steady-state reached in 5-7 days.
Renal: lorazepam is primarily excreted as inactive glucuronide conjugates; <1% is excreted unchanged. Total: ~95% excreted in urine, ~5% in feces.
Renal (60-80% as metabolites, mainly glucuronide conjugates; <2% as unchanged drug). Biliary/fecal excretion accounts for ~10-20%.
