ACUVUE THERAVISION WITH KETOTIFEN vs HYDROXYZINE PAMOATE
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.
Hydroxyzine pamoate is a piperazine derivative with antihistamine (H1 receptor antagonist) and anticholinergic properties. It also has sedative, anxiolytic, and antiemetic effects, likely mediated through suppression of subcortical regions of the central nervous system.
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: 50-100 mg every 6 hours as needed for pruritus or anxiety; maximum 600 mg/day. IM: 25-100 mg every 4-6 hours as needed.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal elimination half-life is approximately 20 hours (range 14-25 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 hepatic metabolism; <1% excreted unchanged in urine. Biliary/fecal elimination accounts for approximately 50% of metabolites.
