ACUVUE THERAVISION WITH KETOTIFEN vs CHLORPHENIRAMINE 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.
H1 receptor antagonist; competitively blocks histamine at H1 receptors, preventing histamine-mediated symptoms such as vasodilation, increased capillary permeability, and smooth muscle contraction.
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 per day; or 10-20 mg intramuscularly or intravenously as a single dose, not to exceed 40 mg per day.
