CHILDREN'S CETIRIZINE HYDROCHLORIDE HIVES RELIEF vs ZADITOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cetirizine is a selective histamine H1-receptor antagonist. It inhibits the H1 receptor, reducing histamine-mediated effects such as edema, flare, and pruritus.
Selective histamine H1 receptor antagonist. Stabilizes mast cells, reducing release of histamine and other mediators of allergic response.
5 mg or 10 mg orally once daily; maximum 10 mg per day.
1 drop in each affected eye twice daily, approximately 6-8 hours apart.

Terminal elimination half-life is approximately 8.3 hours in healthy adults; prolonged to ~20 hours in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 7 hours in adults, which supports twice-daily dosing for sustained ocular effects.
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10% is eliminated in feces.
Primarily renal excretion as unchanged drug (approximately 30-40% of dose) and biliary/fecal elimination of metabolites (60-70%).
