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.
Benzodiazepine that enhances GABA-A receptor activity, increasing chloride ion conductance and neuronal hyperpolarization.
0.25 mg orally once daily at bedtime, maximum 0.5 mg per day.
0.5-2 mg slow IV over 2 minutes, may repeat q2-3min; typical total dose 2.5-5 mg. IM: 0.07-0.08 mg/kg (usual 5 mg).

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 is 1.8-2.5 hours in healthy adults. In critically ill patients or those with hepatic impairment, half-life may extend to 2-6 hours. Obesity may prolong half-life due to increased volume of distribution.
Primarily renal (80%) as conjugated metabolites; fecal (8%); unchanged drug <1%.
Primarily renal elimination of hydroxylated metabolites (midazolam 1-hydroxymidazolam and 4-hydroxymidazolam) as glucuronide conjugates. Only 0.03% of unchanged drug is excreted renally. Fecal excretion accounts for <2%.
