FLAC vs FLUOROMETHOLONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FLAC (Fluorouracil) is a pyrimidine analog that inhibits thymidylate synthase, blocking DNA synthesis. It is converted to active metabolites (FdUMP, FUTP) that disrupt RNA function and DNA replication.
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.
Adults: 40 mg orally twice daily.
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
moderate2-4 hours; prolonged in renal impairment (up to 12 hours)
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: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal (primarily as metabolites): ~70%; Fecal: ~20%; Unchanged in urine: <5%
