FLAC vs TRYMEX
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.
TRYMEX is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity by blocking the reuptake of serotonin at the presynaptic neuron, enhancing neurotransmission in the central nervous system.
Adults: 40 mg orally twice daily.
Adults: 500 mg orally twice daily or 1 g intravenously once daily.

2-4 hours; prolonged in renal impairment (up to 12 hours)
Terminal elimination half-life is 12-15 hours in adults with normal renal function; extends to 30-40 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%
Renal excretion of unchanged drug accounts for 60-70% of dose; biliary/fecal elimination contributes 20-30%, with <5% as metabolites.
