FLUOTREX vs U-CORT
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.
U-CORT (hydrocortisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and subsequent anti-inflammatory, immunosuppressive, and metabolic effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses cytokine production and immune cell migration.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
U-CORT (hydrocortisone) 100 mg intravenous bolus, followed by 100 mg intravenous every 8 hours for 48 hours, then taper as clinically indicated.

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 half-life approximately 1.6-2.2 hours; clinically used as short-acting topical corticosteroid.
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.
Primarily hepatic metabolism; inactive metabolites excreted renally (60-70%) and biliary/fecal (20-30%).
