ACUVUE THERAVISION WITH KETOTIFEN vs CHILDREN'S ZYRTEC HIVES
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.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors, inhibiting histamine-mediated allergic reactions.
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.
5 mg or 10 mg orally once daily; maximum 10 mg/day.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life is approximately 8-11 hours in healthy adults, allowing twice-daily dosing.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Cetirizine is primarily excreted renally (~60% unchanged), with ~10% fecal excretion.
