LORAZEPAM INTENSOL vs NIRAVAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and 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.
0.5-2 mg orally every 6-8 hours as needed. Maximum 4 mg/day.
0.25–0.5 mg sublingually every 6–8 hours as needed; maximum 2 mg/day.

Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in elderly (15-20 hours) and patients with hepatic impairment (up to 30-40 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 glucuronide conjugates; <1% unchanged drug excreted renally. Fecal elimination accounts for approximately 10% of administered dose.
Renal: ~90% as metabolites (glucuronide conjugates and oxidized products), <5% unchanged. Fecal: <10%.
