FLUOTREX vs MICORT-HC
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 that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine release, thereby exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
Topical: Apply a thin film to affected area 2-4 times daily. Rectal: Insert one suppository (25 mg) rectally twice daily (morning and evening) for 2-3 weeks, then taper as needed.

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 1.5-2.5 hours; clinical duration of action is longer due to genomic effects lasting 8-12 hours.
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.
Renal (approximately 70% as inactive metabolites, <5% unchanged); fecal (approximately 30%)
