CORTAN vs FLUOTREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
The active metabolite of FLUOTREX, 5-fluorouracil (5-FU), inhibits thymidylate synthase, leading to depletion of thymidine triphosphate and inhibition of DNA synthesis. Additionally, it incorporates into RNA, disrupting RNA function.
5-60 mg orally once daily, titrated to the lowest effective dose. Maintenance: 5-20 mg daily.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.

Terminal elimination half-life 1.5–2 hours; clinical context: short duration requires multiple daily doses for sustained effect
Terminal elimination half-life is approximately 3-5 hours in adults with normal renal function. In patients with renal impairment, half-life may be prolonged up to 10-15 hours, necessitating dose adjustment.
Renal: 80% as metabolites and unchanged drug; biliary/fecal: 20%
Primarily renal excretion as unchanged drug (approximately 60-70% of administered dose), with the remainder eliminated via biliary/fecal routes (20-30%) and minor metabolic clearance.
