FLAC vs KENACORT
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.
Glucocorticoid receptor agonist; inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis; suppresses cytokine production and immune cell migration.
Adults: 40 mg orally twice daily.
Kenacort (triamcinolone acetonide) is a corticosteroid. For adults, typical dosing is 40-80 mg intramuscularly (deep intragluteal) as a single injection; oral tablets: 4-48 mg/day divided every 6-12 hours; intra-articular: 5-40 mg depending on joint size.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal elimination half-life: 2-5 hours (triamcinolone acetonide). Clinical context: Short half-life supports alternate-day dosing for chronic conditions; however, adrenal suppression may persist longer.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal: 25-30% as unchanged drug and metabolites. Biliary/fecal: 50-70% as metabolites, with enterohepatic circulation.
