FLUOTREX vs LOCORTEN
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.
Corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. Binds to glucocorticoid receptors, modulating gene expression to inhibit prostaglandin and leukotriene synthesis, reduce cytokine release, and suppress immune cell activation.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
For mild to moderate dermatoses: Apply a thin film to affected area twice daily. For severe dermatoses: Apply a thin film to affected area three to four times daily. Topical use only. Not for ophthalmic use.

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.
100 hours (terminal). Clinical context: prolonged in hepatic impairment; single daily dosing sufficient for psoriasis.
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: ~75% (inactive metabolites); biliary/fecal: ~25%. <1% unchanged.
