Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
Olopatadine hydrochloride is a selective histamine H1 receptor antagonist and mast cell stabilizer. It inhibits histamine release from mast cells and prevents histamine-induced effects such as increased vascular permeability and pruritus.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed, up to a maximum of 80 mg/day.
One drop of 0.1% or 0.2% ophthalmic solution in each affected eye twice daily (every 6-8 hours) for 0.1%; once daily for 0.2%.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life of 8–12 hours in healthy adults; prolonged in hepatic impairment (up to 18 hours)
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
