ACUVUE THERAVISION WITH KETOTIFEN vs LEVOCETIRIZINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ketotifen is a selective histamine H1-receptor antagonist and mast cell stabilizer that inhibits the release of inflammatory mediators such as histamine and leukotrienes from mast cells.
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.
One drop in each affected eye twice daily (approximately 8 hours apart) as needed. The lens should be removed prior to instillation and can be reinserted after at least 10 minutes.
Oral, 5 mg once daily in the evening.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
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 (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Approximately 85% renal excretion as unchanged drug via glomerular filtration and tubular secretion, 12.9% fecal excretion, <1% biliary.
