Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to benzodiazepine site on GABA-A receptor, enhancing GABA-mediated chloride ion influx, leading to neuronal hyperpolarization and reduced excitability.
Triazolam is a benzodiazepine that enhances the effect of GABA at the GABA-A receptor, increasing chloride ion conductance and causing neuronal hyperpolarization, leading to CNS depression.
Oral: 5-25 mg 3-4 times daily, up to 100 mg/day in severe anxiety; IM/IV: 50-100 mg initially, then 25-50 mg 3-4 times daily.
0.25 mg orally once daily at bedtime, maximum 0.5 mg per day.

Terminal elimination half-life: 6.6 to 28 hours (parent drug); clinically, duration of effect may be prolonged due to active metabolite nordazepam (half-life 30-100 hours), especially in elderly or hepatic impairment.
Terminal elimination half-life is 1.5–5.5 hours (mean 2.5 hours). Short half-life minimizes next-day sedation.
Renal: approximately 50-60% as metabolites (mainly conjugated forms), with less than 1% unchanged. Fecal: minor, about 10%. Biliary excretion contributes to enterohepatic circulation.
Primarily renal (80%) as conjugated metabolites; fecal (8%); unchanged drug <1%.
