CORTALONE vs FLUOTREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortisone is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response, and regulate metabolism.
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.
10-40 mg orally once daily in the morning; for acute exacerbations, up to 60 mg/day divided into 2-4 doses.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.

Terminal elimination half-life is 3-5 hours in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min).
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 renal (60-70% as unchanged drug), with 10-20% biliary/fecal.
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.
