Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to benzodiazepine site on GABA-A receptors, enhancing chloride ion influx and hyperpolarization of neurons, resulting in anxiolytic, sedative, and muscle relaxant effects.
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.
10-30 mg orally, 3-4 times daily.
0.25 mg orally once daily at bedtime, maximum 0.5 mg per day.

60-120 hours (mean 100 hours); long half-life leads to accumulation upon multiple dosing and prolonged sedation.
Terminal elimination half-life is 1.5–5.5 hours (mean 2.5 hours). Short half-life minimizes next-day sedation.
Renal (primarily as glucuronide conjugates; <1% unchanged); biliary/fecal: minimal (less than 5%).
Primarily renal (80%) as conjugated metabolites; fecal (8%); unchanged drug <1%.
