FLUOTREX vs LOCOID
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 properties. 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.
Topical: Apply a thin layer to affected area once or twice daily. Maximum: 30-60 g per week. Not for use >2 consecutive weeks or on >50% of body surface.

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: 30-40 hours; clinically significant for once-daily dosing and prolonged action
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 60-70%) as conjugated metabolites; biliary/fecal (approximately 20-30%)
