ACUVUE THERAVISION WITH KETOTIFEN vs FAYOSIM
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.
FAYOSIM (plecanatide) is a guanylate cyclase-C (GC-C) agonist. It binds to GC-C receptors on the luminal surface of intestinal epithelial cells, activating the receptor and increasing intracellular cyclic guanosine monophosphate (cGMP) levels. Elevated cGMP stimulates chloride and bicarbonate secretion into the intestinal lumen, enhancing fluid secretion and accelerating gastrointestinal transit, thereby promoting bowel movements.
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.

12 hours (terminal elimination half-life; clinical context: twice-daily dosing needed for continuous effect).
12-16 hours in healthy adults; prolonged to 20-30 hours in moderate renal impairment (CrCl <50 mL/min) requiring dose adjustment.
Renal (approximately 50% as unchanged drug, 30% as metabolites); biliary/fecal elimination accounts for <10%.
Primarily renal elimination, 80% unchanged drug in urine; 15% biliary/fecal; 5% metabolized.
