DITATE-DS vs FLAC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DITATE-DS is a combination of dexamethasone, a corticosteroid with anti-inflammatory and immunosuppressant properties, and trimethoprim, a folate antagonist. Dexamethasone acts by binding to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response. Trimethoprim inhibits dihydrofolate reductase, blocking bacterial folate synthesis and exerting antibacterial effects.
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 tablet (0.5 mg dexamethasone/5 mg cyproheptadine) orally every 8 hours, maximum 3 tablets daily.
Adults: 40 mg orally twice daily.

Terminal elimination half-life is 4-6 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
2-4 hours; prolonged in renal impairment (up to 12 hours)
Renal (50-60% as unchanged drug and metabolites), biliary/fecal (40-50% as metabolites and unchanged drug).
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
