FLUOTREX vs LIDEX
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.
Glucocorticoid receptor agonist; inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis; suppresses inflammatory cytokines and immune cell migration.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
Apply a thin film to affected skin areas twice daily. Not for ophthalmic, oral, or intravaginal 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.
Terminal elimination half-life: 28-36 hours. Clinical context: Steady-state achieved in ~5-7 days; once-daily dosing maintains therapeutic levels without accumulation in patients with normal renal function.
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 (primarily as metabolites) ~ 95%; biliary/fecal ~5%.
