ACUVUE THERAVISION WITH KETOTIFEN vs LORATADINE
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 tricyclic antihistamine with selective peripheral H1-receptor antagonist activity. It inhibits histamine-induced vasodilation and bronchoconstriction.
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).
Clinical Note
moderateLoratadine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Loratadine is combined with Fluticasone propionate."
Clinical Note
moderateLoratadine + Teriflunomide
"The metabolism of Teriflunomide can be decreased when combined with Loratadine."
Clinical Note
moderateLoratadine + Haloperidol
"The metabolism of Haloperidol can be decreased when combined with Loratadine."
Clinical Note
moderateLoratadine + Sulfisoxazole
Loratadine: 8-14 hours (mean ~10 hours). Active metabolite descarboethoxyloratadine: 17-24 hours (mean ~20 hours). Clinically, duration supports once-daily dosing.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Approximately 40% excreted in urine as metabolites (primarily descarboethoxyloratadine) and 40% in feces as metabolites; <1% excreted unchanged.
