Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Topical corticosteroid that induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which inhibit the release of arachidonic acid, thereby reducing prostaglandin and leukotriene synthesis, and exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
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: Apply a thin film to affected area 3-4 times daily. Dosage strength: 0.5% cream or ointment.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.

Terminal elimination half-life: 1–2 hours for hydrocortisone (active component), prolonged in liver disease or with concurrent CYP3A4 inhibitors.
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.
Primarily hepatic metabolism (approximately 95%) followed by renal excretion of inactive metabolites (<5% unchanged). Biliary/fecal excretion is negligible.
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.
