FML-S vs OPTOMYCIN
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.
Optomycin is a semi-synthetic glycopeptide antibiotic that inhibits bacterial cell wall synthesis by binding to the D-alanyl-D-alanine terminus of the peptidoglycan precursor, preventing transpeptidation and cross-linking.
1-2 drops of 0.1% ophthalmic suspension into the conjunctival sac every 4 hours; may increase to every 2 hours in severe inflammation.
1.5 mg/kg IV every 8 hours; alternatively, 5-7 mg/kg IV daily.
