Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
Antihistamine with mast cell stabilizing properties; selectively antagonizes histamine H1 receptors, reducing nasal pruritus, sneezing, rhinorrhea, and ocular symptoms.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed, up to a maximum of 80 mg/day.
One spray (137 mcg) per nostril twice daily (total 548 mcg/day). Intranasal route.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
The terminal elimination half-life is approximately 22 hours (range 16-26 hours) at steady state, supporting twice-daily dosing. The half-life may be prolonged in elderly patients or those with hepatic impairment.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Azelastine is primarily eliminated via renal excretion (approximately 75% as metabolites, <10% unchanged) and fecal excretion (approximately 25%) after oral administration. Biliary excretion is minimal.
