ACUVUE THERAVISION WITH KETOTIFEN vs AZELASTINE HYDROCHLORIDE CHILDREN'S 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.
Azelastine hydrochloride is a phthalazinone derivative that acts as a selective histamine H1-receptor antagonist. It inhibits the release of histamine and other mediators from mast cells, reduces chemotaxis, and decreases eosinophil activation. It also suppresses leukotriene and cytokine production.
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.
Azelastine hydrochloride nasal spray: 1 spray (137 mcg) per nostril twice daily; maximum 2 sprays per nostril twice daily.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life is 22–25 hours in adults; steady state achieved in 3–5 days. In children (6–11 years), half-life is similar (mean 22 hours).
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Primarily renal (approximately 75%), with about 50% as unchanged drug and 25% as metabolites via CYP3A4 and CYP2D6. Fecal excretion accounts for ~20%.
