FLUOTREX vs WESTCORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Topical corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive actions. Binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
Apply a thin film to affected area twice daily. Use for no longer than 2 consecutive weeks.

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.
Terminal elimination half-life is 2-4 hours. Clinical context: Requires multiple daily applications for sustained effect; systemic accumulation unlikely with topical use.
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.
Primarily renal (70-90% as metabolites, <5% unchanged); minor biliary/fecal (10-20%)
