Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
Levocetirizine is a selective histamine H1-receptor antagonist; it inhibits the histamine-mediated responses in allergic conditions.
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 7 hours in healthy adults; prolonged to 8–11 hours in elderly and in renal impairment.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Approximately 84% of a dose is excreted renally as unchanged drug; 12% in feces via biliary elimination.
