FLUOTREX vs TOPICORT
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 induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which inhibit the release of arachidonic acid, thereby reducing production of prostaglandins and leukotrienes, leading to anti-inflammatory, antipruritic, and vasoconstrictive effects.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
Apply a thin film to the affected skin areas twice daily. Maximum adult dose: 50 g/week. Not for use on the face, axillae, or groin. Do not use under occlusive dressings.

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: 2-4 hours for parent drug; clinical effect lasts longer due to receptor binding
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 (metabolites): ~75%; Fecal: ~25%
