FLUOROMETHOLONE vs MAXIDEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
MAXIDEX (dexamethasone) is a potent glucocorticoid that binds to the glucocorticoid receptor (GR), leading to modulation of gene expression and inhibition of inflammatory mediators such as prostaglandins and leukotrienes. It suppresses immune response through inhibition of cytokine production (e.g., IL-1, IL-2, TNF-alpha) and reduces vasodilation and vascular permeability.
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.
One to two drops of the 0.1% ophthalmic suspension into the conjunctival sac every hour during the day and every two hours at night initially; after improvement, reduce to one drop every four hours, then one drop three to four 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: 1.3–2.2 hours; However, the pharmacodynamic half-life (duration of adrenal suppression) is longer (~24–36 hours) due to receptor-mediated effects.
Terminal elimination half-life is approximately 2-3 hours for dexamethasone; in ocular tissues, half-life may be prolonged due to local retention, but systemic half-life is short with minimal accumulation.
Renal (primarily as metabolites): ~70%; Fecal: ~20%; Unchanged in urine: <5%
Primarily hepatic metabolism via CYP3A4; renal excretion of metabolites accounts for <15% unchanged drug; biliary/fecal elimination of metabolites predominates.
