FEXOFENADINE HYDROCHLORIDE ALLERGY vs KALLIGA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a selective peripheral H1-receptor antagonist that inhibits histamine release from mast cells and basophils.
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.
60 mg orally twice daily or 180 mg orally once daily.
0.5 mg orally once daily, titrated to 1 mg once daily after 2-4 weeks if tolerated.

Terminal elimination half-life is 14.4 hours in healthy adults. In renal impairment, half-life may be prolonged up to 59 hours.
Terminal elimination half-life: 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min)
Primarily excreted unchanged in feces (80%) and urine (11%). Biliary excretion contributes to fecal elimination.
Renal excretion: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
