FLAC vs ORAPRED ODT
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.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and subsequent anti-inflammatory and immunosuppressive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses cytokine production.
Adults: 40 mg orally twice daily.
10-60 mg orally once daily or divided twice daily; maximum 60 mg/day.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal elimination half-life: 2-3 hours (after IV/IM/oral). Clinically, anti-inflammatory effects persist beyond plasma half-life due to glucocorticoid receptor-mediated gene transcription effects.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Primarily renal (80-90% as inactive glucuronide and sulfate conjugates; less than 10% as unchanged drug). Biliary/fecal excretion accounts for about 5%.
