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 antagonist of peripheral histamine H1 receptors, blocking histamine-induced allergic responses by inhibiting H1 receptor activation in the gastrointestinal tract, blood vessels, and respiratory tract.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed, up to a maximum of 80 mg/day.
5 mg orally once daily in the evening.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life: 7-11 hours in adults. Clinically, this supports once-daily dosing; may be prolonged in renal impairment (creatinine clearance <30 mL/min).
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Renal: 85% as unchanged drug (70%) and metabolites (15%); fecal: 13%; biliary: minimal (<2%).
