ACUVUE THERAVISION WITH KETOTIFEN vs TRIPROLIDINE AND PSEUDOEPHEDRINE
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.
Triprolidine is a first-generation antihistamine that antagonizes histamine H1 receptors, reducing histamine-mediated allergic symptoms. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction and decreased 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.
1 tablet (2.5 mg triprolidine/60 mg pseudoephedrine) orally every 4-6 hours; max 4 tablets/24 hours.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Triprolidine: 2-4 hours (parent compound). Pseudoephedrine: 4-8 hours, prolonged in alkaline urine (up to 16-24 hours).
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Triprolidine: renal, 70% unchanged and metabolites. Pseudoephedrine: renal, 90% unchanged.
