CHILDREN'S CETIRIZINE HYDROCHLORIDE ALLERGY vs DISOMER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors. It inhibits the H1 receptor-mediated effects of histamine, reducing symptoms such as pruritus, sneezing, rhinorrhea, and urticaria. It also decreases eosinophil chemotaxis and adhesion molecule expression.
Selective dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
5-10 mg orally once daily; max 10 mg/day. For children's formulation, typical adult dose applies to patients >12 years.
Adults: 1 mg orally once daily.

Approximately 8.3 hours (range 6–10 hours) in healthy adults; prolonged in renal impairment (e.g., up to 20 hours).
12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
Renal: ~60% unchanged; fecal: ~10%; minor biliary elimination.
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
