FLAC vs FLUDROCORTISONE ACETATE
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.
Mineralocorticoid receptor agonist; promotes sodium reabsorption and potassium excretion in renal distal tubules, increasing extracellular fluid volume. Also has glucocorticoid activity.
Adults: 40 mg orally twice daily.
0.1 mg orally once daily, range 0.05-0.2 mg/day

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal elimination half-life is 3.5 hours (range 2–5 h); clinical effect duration exceeds half-life due to mineralocorticoid receptor binding.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal (80%) as inactive metabolites; less than 5% unchanged; minor biliary/fecal elimination.
