Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors, inhibiting histamine-mediated allergic reactions.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed, up to a maximum of 80 mg/day.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life is approximately 8-11 hours in healthy adults, allowing twice-daily dosing.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Cetirizine is primarily excreted renally (~60% unchanged), with ~10% fecal excretion.
