Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
H1-receptor antagonist; competes with histamine for H1-receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract, blocking histamine-induced bronchoconstriction, vasodilation, and increased capillary permeability.
Levocetirizine is a selective peripheral histamine H1-receptor antagonist. It inhibits the effects of histamine at the H1 receptor, reducing allergic symptoms such as itching, sneezing, and rhinorrhea. It has lower affinity for central H1 receptors and anticholinergic properties compared to first-generation antihistamines.
2.5 mg orally every 4 to 6 hours as needed; maximum 10 mg per day.
Oral, 5 mg once daily in the evening.

Terminal elimination half-life is approximately 20-25 hours in healthy adults; may be prolonged in elderly or patients with hepatic impairment.
Terminal elimination half-life: 7–8 hours in healthy adults; prolonged to 20–24 hours in renal impairment (CrCl <40 mL/min); clinically, stable levels require 2–3 days.
Renal excretion of unchanged drug and metabolites accounts for approximately 60-80% of the administered dose; biliary/fecal elimination comprises the remainder (20-40%).
Approximately 85% renal excretion as unchanged drug via glomerular filtration and tubular secretion, 12.9% fecal excretion, <1% biliary.
