FLAC vs SOLU-CORTEF
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.
Solu-Cortef (hydrocortisone sodium succinate) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators, including prostaglandins and leukotrienes. It also inhibits immune cell migration and activation.
Adults: 40 mg orally twice daily.
100-1000 mg intravenous (IV) or intramuscular (IM), then 100-500 mg IV or IM every 2-6 hours as needed.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal elimination half-life: 1.5-2 hours (hydrocortisone); clinical duration of action is longer due to genomic effects (6-8 hours).
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal: ~80% as metabolites (mainly 17-hydroxycorticosteroids) and <5% unchanged. Biliary/fecal: minimal (<5%).
