Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine H1 receptors; inhibits histamine-mediated vasodilation, increased capillary permeability, and bronchoconstriction in allergic reactions.
Selective histamine H1-receptor antagonist; inhibits histamine release from mast cells and basophils.
2.5 mg orally every 4-6 hours as needed; maximum 10 mg per 24 hours.
5-10 mg orally once daily; maximum 10 mg/day.

Terminal elimination half-life approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Terminal elimination half-life is approximately 8-11 hours in healthy adults, prolonged in renal impairment (e.g., up to 20 hours in moderate renal failure).
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
Cetirizine is primarily excreted unchanged in urine (approximately 70% renal elimination) and feces (about 10%).
