CORTIFOAM vs FLAC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortifoam (hydrocortisone acetate) is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, antipruritic, and vasoconstrictive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses immune cell migration and cytokine release.
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.
1 applicatorful (90 mg hydrocortisone acetate) rectally twice daily for 2-3 weeks, then every other day as needed.
Adults: 40 mg orally twice daily.

None Documented
Approximately 1.5-2 hours for hydrocortisone; clinically, effects persist longer due to local action.
2-4 hours; prolonged in renal impairment (up to 12 hours)
Primarily renal (about 70-90% as metabolites) and fecal (about 10-30% as metabolites).
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
