Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine at H1 receptor sites, suppressing histamine-induced vasodilation, increased capillary permeability, and bronchoconstriction.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors, inhibiting histamine-mediated allergic reactions.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.
5 mg or 10 mg orally once daily; maximum 10 mg/day.

Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
Terminal elimination half-life is approximately 8-11 hours in healthy adults, allowing twice-daily dosing.
Renal (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
Cetirizine is primarily excreted renally (~60% unchanged), with ~10% fecal excretion.
