FML-S vs PEDIOTIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluorometholone is a synthetic corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2 activity, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production. This results in decreased inflammation, edema, and immune cell infiltration. Sulfacetamide is a sulfonamide antibiotic that competitively inhibits dihydropteroate synthase, blocking folate synthesis and bacterial growth.
PEDIOTIC contains hydrocortisone, neomycin, and polymyxin B. Neomycin and polymyxin B are antibiotics that inhibit bacterial protein synthesis and disrupt bacterial cell membrane integrity, respectively. Hydrocortisone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
1-2 drops of 0.1% ophthalmic suspension into the conjunctival sac every 4 hours; may increase to every 2 hours in severe inflammation.
Instill 4 drops into the affected ear(s) twice daily for 7-10 days.

2.8-3.5 hours; prolonged to 8-12 hours in renal impairment or in neonates
Not established for topical otic use; systemic absorption is minimal. If absorbed, terminal half-life of dexamethasone is approximately 3-4 hours.
Renal (65-75% as unchanged drug and metabolites), biliary/fecal (15-25%)
Renal elimination of absorbed drug (primarily unchanged) accounts for <10% of topically applied dose; fecal/biliary routes negligible.
