FLAC vs KERLEDEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FLAC (Fluorouracil) is a pyrimidine analog that inhibits thymidylate synthase, blocking DNA synthesis. It is converted to active metabolites (FdUMP, FUTP) that disrupt RNA function and DNA replication.
Kerledex is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane.
Adults: 40 mg orally twice daily.
Intravenous: 500 mg every 6 hours; Oral: 250 mg every 8 hours.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal half-life 12 hours (range 10–14) in normal renal function; extended to 30–50 hours in severe renal impairment (CrCl <30 mL/min); 6–8 hours in hepatic cirrhosis.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal: 70% unchanged; fecal/biliary: 20% as metabolites; 10% as minor metabolites. Total renal clearance 180 mL/min, active tubular secretion accounts for 60% of renal elimination.
