ACUVUE THERAVISION WITH KETOTIFEN vs TELDRIN
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.
TELDRIN contains loratadine and pseudoephedrine. Loratadine is a long-acting tricyclic antihistamine with selective peripheral H1-receptor antagonism. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction.
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.
1-2 mg orally twice daily; maximum 4 mg/day.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal half-life: 9-12 hours (range 8-14) in healthy adults; prolonged in renal impairment.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Renal: 55-60% unchanged; fecal: 35-40%; minor biliary elimination.
