Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Fluorometholone is a synthetic corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins and leukotrienes. This results in suppression of inflammation, immune response, and fibroblast proliferation.
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.
1 drop of 0.25% ophthalmic suspension in the conjunctival sac of the affected eye(s) every 4 hours. In severe conditions, 1 drop every 2 hours initially, taper as response is achieved.

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.
Plasma terminal elimination half-life is approximately 3-4 hours (range 2-6 hours) for fluorometholone alcohol; clinical effects may persist longer due to tissue retention.
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%.
Eliminated primarily via hepatic metabolism; renal excretion of inactive metabolites accounts for approximately 60-70%, with about 30-40% excreted in feces via bile.
