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.
Midazolam hydrochloride is a benzodiazepine that enhances the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA-A receptor, resulting in increased chloride ion conductance, neuronal hyperpolarization, and inhibition of neuronal transmission. This produces sedative, anxiolytic, amnestic, and anticonvulsant effects.
0.25 mg orally once daily at bedtime, maximum 0.5 mg per day.
2.5-10 mg IV bolus for induction; 0.05-0.2 mg/kg/h IV infusion for sedation. IM: 0.07-0.08 mg/kg (max 5 mg) 30-60 min pre-procedure.

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: 1.5-3 hours in healthy adults; prolonged in elderly (up to 6 hours), obesity, hepatic cirrhosis (up to 20 hours), and congestive heart failure.
Primarily renal (80%) as conjugated metabolites; fecal (8%); unchanged drug <1%.
Renal excretion of metabolites (approximately 90% as glucuronide conjugates, with less than 1% unchanged drug) and biliary/fecal excretion (approximately 5-10%).
