DEXONE 4 vs FLUOROMETHOLONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce phospholipase A2 inhibitory proteins, thereby reducing prostaglandin and leukotriene synthesis. Exhibits anti-inflammatory, antipruritic, and vasoconstrictive effects.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
1-2 drops of 0.1% suspension in conjunctival sac 2-4 times daily; severe cases: every 4 hours initially, then taper. Ointment: 0.5 inch ribbon 1-3 times daily.

Clinical Note
moderateFluorometholone + Gatifloxacin
"The risk or severity of adverse effects can be increased when Fluorometholone is combined with Gatifloxacin."
Clinical Note
moderateFluorometholone + Rosoxacin
"The risk or severity of adverse effects can be increased when Fluorometholone is combined with Rosoxacin."
Clinical Note
moderateFluorometholone + Levofloxacin
"The risk or severity of adverse effects can be increased when Fluorometholone is combined with Levofloxacin."
Clinical Note
moderateTerminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
Terminal elimination half-life: 1.3–2.2 hours; However, the pharmacodynamic half-life (duration of adrenal suppression) is longer (~24–36 hours) due to receptor-mediated effects.
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
Renal (primarily as metabolites): ~70%; Fecal: ~20%; Unchanged in urine: <5%
