ACUVUE THERAVISION WITH KETOTIFEN vs FEXOFENADINE HYDROCHLORIDE 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.
Fexofenadine hydrochloride is a selective peripheral H1-receptor antagonist. It blocks the action of histamine at the H1 receptor, preventing histamine-mediated symptoms such as itching, sneezing, rhinorrhea, and urticaria.
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.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life is 14.4 hours (range 11–17 hours) in healthy adults. Clinically, this supports twice-daily dosing for symptomatic relief.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Approximately 95% of the dose is excreted unchanged in feces (80%) and urine (15%). Fexofenadine undergoes minimal hepatic metabolism (<5%).
