CORTENEMA vs FLAC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
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.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
Adults: 40 mg orally twice daily.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
2-4 hours; prolonged in renal impairment (up to 12 hours)
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
