FLAC vs TRIACORT
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.
Adrenocorticosteroid; binds to glucocorticoid receptor, modulating gene expression to produce anti-inflammatory, immunosuppressive, and metabolic effects.
Adults: 40 mg orally twice daily.
10-20 mg orally once daily

2-4 hours; prolonged in renal impairment (up to 12 hours)
2-3 h. The terminal elimination half-life is short, requiring thrice-daily dosing for sustained effect. Context: In patients with hepatic impairment, half-life may be prolonged up to 4-5 h.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Primarily hepatic metabolism (>90%) with renal excretion of inactive metabolites (approximately 80% in urine, 20% in feces). Less than 5% of the parent drug is excreted unchanged in urine.
