ACUVUE THERAVISION WITH KETOTIFEN vs TRIPHED
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 competitively antagonizes histamine at H1 receptors, thereby alleviating symptoms of allergic reactions. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction and reducing edema.
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.
Adults: Triprolidine 2.5 mg / pseudoephedrine 60 mg orally every 4-6 hours, not to exceed 4 doses in 24 hours.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life is 6-8 hours in adults with normal renal function; clinically, dosing interval adjustments are recommended in renal impairment.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Renal excretion of unchanged drug and metabolites accounting for approximately 60-70% of elimination; biliary/fecal elimination accounts for 20-30%.
