AZELASTINE HYDROCHLORIDE ALLERGY vs KALLIGA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine with mast cell stabilizing properties; selectively antagonizes histamine H1 receptors, reducing nasal pruritus, sneezing, rhinorrhea, and ocular symptoms.
KALLIGA is a recombinant urate oxidase enzyme that catalyzes the oxidation of uric acid to allantoin, a more soluble and easily excreted metabolite, thereby reducing serum uric acid levels.
One spray (137 mcg) per nostril twice daily (total 548 mcg/day). Intranasal route.
0.5 mg orally once daily, titrated to 1 mg once daily after 2-4 weeks if tolerated.

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.
Terminal elimination half-life: 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min)
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.
Renal excretion: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
