ACUVUE THERAVISION WITH KETOTIFEN vs CYPROHEPTADINE HYDROCHLORIDE
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.
Cyproheptadine is a potent antihistamine (H1 receptor antagonist) and antiserotonergic agent (5-HT2 receptor antagonist). It also exhibits weak anticholinergic and sedative properties. It blocks histamine-mediated vasodilation, increased capillary permeability, and pruritus, as well as serotonin-mediated effects on appetite and mood.
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 three times daily; range 4-20 mg/day, not to exceed 0.5 mg/kg/day

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal half-life approximately 8–16 hours in adults; may be prolonged in elderly or hepatic impairment.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Primarily renal (appreciable unchanged drug and metabolites); biliary/fecal elimination minor (<5%).
