ACUVUE THERAVISION WITH KETOTIFEN vs TRINALIN
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.
TRINALIN is a combination of azatadine, a first-generation antihistamine that antagonizes histamine H1 receptors, and pseudoephedrine, a sympathomimetic amine that stimulates alpha-adrenergic receptors, causing vasoconstriction and reducing nasal congestion.
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.
One tablet (azatadine 1 mg/pseudoephedrine 120 mg) orally every 12 hours. Not to exceed 2 tablets in 24 hours.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life approximately 20-30 hours; clinical context: allows twice-daily dosing for sustained decongestant effect
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Renal: 70-80% as unchanged drug and metabolites; biliary/fecal: 20-30%
