Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that inhibits phospholipase A2 activity, reducing arachidonic acid release and subsequent production of prostaglandins and leukotrienes, thereby suppressing ocular inflammation.
Fluorometholone is a corticosteroid that inhibits phospholipase A2, reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis, thereby suppressing inflammatory responses.
1-2 drops in the conjunctival sac every hour during the day and every 2 hours at night initially; after response, reduce to 1 drop every 4 hours, then 1 drop 3-4 times daily. Ophthalmic suspension.
2 drops of 0.1% solution into the affected eye(s) every 15 minutes for 4 doses, then every 30 minutes for 2 doses, then every 1-2 hours for 24-48 hours, then tapering over 1-2 weeks; alternatively, 0.5 cm ribbon of 0.05% ointment into the conjunctival sac 4-6 times daily.

Terminal elimination half-life is approximately 1-2 hours (mean 1.3 hours) in adults. Due to rapid clearance, accumulation is minimal with topical ophthalmic dosing, but prolonged use may lead to systemic absorption and slightly extended half-life.
Terminal elimination half-life is 3-6 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
Primarily hepatic metabolism, with inactive metabolites excreted renally (approximately 60-80%) and fecally (20-40%). Less than 5% of unchanged drug appears in urine.
Renal excretion of unchanged drug accounts for approximately 60-80% of elimination, with the remainder as metabolites (glucuronide conjugates) via urine; fecal elimination is minimal (<5%).
