ACUVUE THERAVISION WITH KETOTIFEN vs BROMPHENIRAMINE MALEATE
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.
Competitive antagonist of histamine at H1 receptor sites, suppressing histamine-induced vasodilation, increased capillary permeability, 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.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Renal (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
