FLUOTREX vs PSORCON E
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.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to produce anti-inflammatory, antipruritic, and vasoconstrictive effects.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
Topical: Apply a thin film to affected skin areas twice daily. No systemic dosing applicable.

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 is approximately 6-8 hours for the parent compound; active metabolites may have half-lives up to 12 hours. Clinically, this supports twice-daily 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.
Primarily hepatic metabolism followed by renal excretion of metabolites; less than 5% excreted unchanged in urine. Biliary/fecal elimination accounts for <2%.
