Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that potentiates GABA-A receptor activity by binding to the benzodiazepine site, increasing chloride ion conductance and neuronal inhibition.
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.
2 to 10 mg orally 2 to 4 times daily, as needed for anxiety or muscle spasm; 10 mg orally before procedures for sedation. Maximum 40 mg/day.
0.25 mg orally once daily at bedtime, maximum 0.5 mg per day.

Terminal elimination half-life is 20–50 hours (mean ~30 hours) in adults, with significant interindividual variability; prolonged in elderly, hepatic impairment, and neonates (up to 100 hours).
Terminal elimination half-life is 1.5–5.5 hours (mean 2.5 hours). Short half-life minimizes next-day sedation.
Renal excretion of metabolites (primarily glucuronide conjugates) accounts for ~70% of elimination; fecal excretion accounts for ~10%; unchanged drug in urine is <1%.
Primarily renal (80%) as conjugated metabolites; fecal (8%); unchanged drug <1%.
