FLAC vs KENALOG IN ORABASE
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 reduce inflammation, suppress immune response, and inhibit fibroblast proliferation.
Adults: 40 mg orally twice daily.
Apply a thin layer to the affected area 2-4 times daily, after meals and at bedtime. Do not rub in; allow to form a film.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal half-life approximately 2-5 hours following mucosal application.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Primarily hepatic metabolism; metabolites excreted renally (~75%) and in feces (~10%).
