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.
NIRAVAM (alprazolam) is a benzodiazepine that potentiates GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and decreased excitability.
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.
0.25–0.5 mg sublingually every 6–8 hours as needed; maximum 2 mg/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: 8–14 hours (mean 10.5 h). Clinically, steady-state reached in ~3 days; accumulation minimal at typical dosing.
Renal excretion of metabolites (primarily glucuronide conjugates) accounts for ~70% of elimination; fecal excretion accounts for ~10%; unchanged drug in urine is <1%.
Renal: ~90% as metabolites (glucuronide conjugates and oxidized products), <5% unchanged. Fecal: <10%.
