Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective peripheral H1-receptor antagonist. Competitively inhibits histamine at the H1 receptor, preventing histamine-mediated symptoms such as pruritus, sneezing, and rhinorrhea.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors, inhibiting histamine-mediated allergic reactions.
Oral, 10 mg once daily; may be increased to 10 mg twice daily if needed.
5 mg or 10 mg orally once daily; maximum 10 mg/day.

Terminal elimination half-life is approximately 8-11 hours in healthy adults; increases to approximately 20 hours in renal impairment (CrCl <40 mL/min).
Terminal elimination half-life is approximately 8-11 hours in healthy adults, allowing twice-daily dosing.
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; 10% is excreted in feces. Biliary excretion is minimal.
Cetirizine is primarily excreted renally (~60% unchanged), with ~10% fecal excretion.
