LORAZEPAM PRESERVATIVE FREE vs NIRAVAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that enhances GABA-A receptor activity, increasing chloride ion conductance and producing sedative, anxiolytic, anticonvulsant, and muscle relaxant effects.
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.
0.5-2 mg orally every 6-8 hours as needed; maximum 4 mg/day. IV: 0.044 mg/kg (max 4 mg) every 6-8 hours for acute anxiety or sedation.
0.25–0.5 mg sublingually every 6–8 hours as needed; maximum 2 mg/day.

Terminal elimination half-life: 12–14 hours (range 10–20 h). Clinically, no active metabolites; accumulation minimal at standard dosing intervals.
Terminal elimination half-life: 8–14 hours (mean 10.5 h). Clinically, steady-state reached in ~3 days; accumulation minimal at typical dosing.
Renal: ~88% as glucuronide conjugates; <1% unchanged. Fecal: ~7%. Biliary: minor.
Renal: ~90% as metabolites (glucuronide conjugates and oxidized products), <5% unchanged. Fecal: <10%.
