Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluorometholone is a corticosteroid that inhibits phospholipase A2, reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis, thereby suppressing inflammatory responses.
Corticosteroid; modulates inflammatory response by binding to glucocorticoid receptors, altering gene expression and suppressing pro-inflammatory cytokines.
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.
Instill 1 drop into the affected eye(s) four times daily for 14 days, then taper as clinically indicated.

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.
Approximately 1.5 hours (range 1-2 hours) for the ophthalmic suspension; terminal half-life in systemic circulation is about 3 hours after topical ocular administration.
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%).
Primarily hepatic metabolism with minimal renal excretion (<5% unchanged in urine). Fecal elimination accounts for approximately 20% of the dose.
