ACUVUE THERAVISION WITH KETOTIFEN vs ISOCLOR
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.
Chlorpheniramine is an antihistamine (H1-receptor antagonist) that blocks the action of histamine, reducing allergy symptoms. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors, causing vasoconstriction in the nasal mucosa.
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.
Oral: 1 tablet (chlorpheniramine 4 mg / pseudoephedrine 60 mg) every 4-6 hours, not to exceed 4 tablets per 24 hours.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Approximately 2-4 hours in patients with normal renal function; prolonged to 8-12 hours in renal impairment (CrCl <30 mL/min).
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Primarily renal; approximately 60-70% of a dose excreted unchanged in urine within 24 hours. Biliary/fecal excretion accounts for <10%.
