FLUOTREX vs HYTONE
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.
Hydrocortisone (topical) binds to glucocorticoid receptors, activating anti-inflammatory proteins and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
Topical: Apply cream or ointment to affected area 2-4 times daily. Limit treatment area to less than 50% of body surface area. Maximum duration: 2 weeks unless directed by physician.

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.
30–60 minutes (terminal elimination half-life; short duration requires frequent dosing)
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.
