Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective adenosine A2A receptor antagonist; promotes wakefulness by blocking the inhibitory effects of adenosine on arousal-promoting neurons in the brain.
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.
For induction and maintenance of general anesthesia: 0.3 mg/kg intravenously over 30 seconds, followed by an infusion of 1.5 mg/kg/hour adjusted to effect. Additional boluses of 0.075 mg/kg may be given as needed.
0.25–0.5 mg sublingually every 6–8 hours as needed; maximum 2 mg/day.

Terminal elimination half-life is approximately 2-4 hours; clinical context: requires continuous infusion for sustained effect, as rapid clearance may lead to loss of efficacy.
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 accounts for approximately 90% of the administered dose, with <5% as unchanged drug. Biliary/fecal elimination is minimal (<5%).
Renal: ~90% as metabolites (glucuronide conjugates and oxidized products), <5% unchanged. Fecal: <10%.
