FLAC vs TRIACIN-C
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.
TRIACIN-C is a combination of triamcinolone (a corticosteroid) and nystatin (an antifungal). Triamcinolone suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis. Nystatin binds to ergosterol in fungal cell membranes, causing pore formation and cell death.
Adults: 40 mg orally twice daily.
5 mg orally twice daily, taken with meals to enhance absorption.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal elimination half-life: 7–9 hours. In patients with severe hepatic impairment (Child-Pugh C), half-life may extend to 15 hours; dosing adjustment recommended.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal: ~60% as unchanged drug; hepatic metabolism accounts for ~25% (primarily via CYP3A4), with biliary excretion of metabolites (~15%); fecal elimination <5%.
