DEXONE 1.5 vs FLAC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.
1.5 mg orally once daily
Adults: 40 mg orally twice daily.

Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
2-4 hours; prolonged in renal impairment (up to 12 hours)
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
