ACUVUE THERAVISION WITH KETOTIFEN vs CHILDREN'S ALLEGRA ALLERGY
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.
Fexofenadine is a selective peripheral H1-receptor antagonist. It inhibits histamine release from mast cells and basophils, reducing allergic symptoms.
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.
Fexofenadine 60 mg orally twice daily or 180 mg once daily.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life is approximately 14.4 hours (range 11–17 hours) in healthy adults. In children aged 6–12 years, half-life is similar. Clinical context: allows once-daily dosing.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Fexofenadine is excreted primarily unchanged in feces (approximately 80%) and urine (approximately 11%). Biliary excretion accounts for a minor portion.
