ACUVUE THERAVISION WITH KETOTIFEN vs BROMPHERIL
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.
Brompheril is a mu-opioid receptor agonist with additional sigma-1 receptor antagonism, producing analgesic effects and modulating neuropathic pain.
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.
In adults, the usual dose is 1-2 mg/kg intravenously every 4-6 hours as needed. Alternatively, 5 mg can be administered intramuscularly or subcutaneously every 4 hours.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
Terminal half-life 2.5-4 hours; prolonged in renal impairment (up to 12 hours in severe cases).
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Primarily renal (60-70% as unchanged drug); 15-20% fecal via biliary elimination; minor metabolic clearance.
