FLAC vs STERI-STAT
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.
Binds to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis by blocking peptide bond formation and translocation.
Adults: 40 mg orally twice daily.
Adults: 1 gram intravenously every 8 hours infused over 60 minutes.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 18-24 hours in moderate renal impairment (CrCl 30-50 mL/min).
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal excretion of unchanged drug accounts for approximately 95% of elimination; biliary/fecal elimination is minimal (<5%).
