Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid receptor agonist; reduces inflammation by inhibiting phospholipase A2, decreasing prostaglandin and leukotriene synthesis, and suppressing immune cell migration and cytokine release.
Agonist at glucocorticoid receptors, leading to inhibition of phospholipase A2 via annexin-1 induction, reducing prostaglandin and leukotriene synthesis; also suppresses cytokine production and inflammatory cell migration.
1 drop of 0.1% ophthalmic solution in the affected eye(s) four times daily for up to 14 days.
Fluorometholone ophthalmic suspension 0.1%: Instill 1 drop into conjunctival sac 2-4 times daily. In severe conditions, may increase to 1 drop every hour initially.

Terminal elimination half-life is 12–18 hours in adults; prolonged to 24–36 hours in hepatic impairment.
The terminal elimination half-life of fluorometholone is approximately 1.5 hours in plasma. Clinically, this short half-life allows for multiple daily dosing; however, ocular administration results in sustained local effects due to corneal binding.
Renal excretion of unchanged drug accounts for 30% of clearance; biliary/fecal elimination accounts for 60%, with the remainder as metabolites.
FML (fluorometholone) is primarily metabolized in the liver, with metabolites excreted renally. Approximately 70-80% of the dose is eliminated in urine as metabolites, with less than 5% as unchanged drug. Fecal excretion accounts for about 10%.
