Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.

0.25 mg orally once daily at bedtime, maximum 0.5 mg per day.
Oral: 2-10 mg 2-4 times daily. IV/IM: 5-10 mg, repeat in 3-4 hours if needed; max 30 mg in 8 hours.

Terminal elimination half-life is 1.5–5.5 hours (mean 2.5 hours). Short half-life minimizes next-day sedation.
Terminal elimination half-life of diazepam: 20–50 hours; active metabolite desmethyldiazepam half-life: 36–200 hours (accumulates with chronic dosing, prolonging clinical effects).
Primarily renal (80%) as conjugated metabolites; fecal (8%); unchanged drug <1%.
Renal: <1% unchanged; hepatic metabolism to active metabolites (desmethyldiazepam, temazepam, oxazepam); metabolites excreted renally as glucuronides. Fecal: minor.
