ACUVUE THERAVISION WITH KETOTIFEN vs CHILDREN'S CLARITIN
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.
Loratadine is a long-acting second-generation antihistamine that selectively antagonizes peripheral histamine H1 receptors, thereby inhibiting the effects of histamine released from mast cells and basophils, reducing allergic symptoms.
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.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
The terminal elimination half-life of loratadine is 8-14 hours (mean 11 hours) in healthy adults; for the active metabolite descarboethoxyloratadine, half-life is 17-24 hours (mean 20 hours). This supports once-daily dosing.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Loratadine is primarily eliminated via hepatic metabolism, with approximately 80% of the dose excreted as metabolites in urine (40%) and feces (40%). Less than 1% is excreted unchanged in urine.
