ACUVUE THERAVISION WITH KETOTIFEN vs CLARINEX
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.
Desloratadine is a long-acting tricyclic histamine antagonist with selective peripheral H1-receptor antagonist activity. It inhibits histamine release from mast cells and reduces allergic inflammation.
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.
5 mg orally once daily.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life is approximately 27 hours (range 20-30 hours). This long half-life supports once-daily dosing and allows for steady-state concentrations within 7 days.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Desloratadine is primarily eliminated via renal excretion (~40% as metabolites) and fecal elimination (~45% as metabolites). Less than 2% is excreted unchanged in urine.
