Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Flucytosine is converted intracellularly to 5-fluorouracil, which inhibits fungal RNA and DNA synthesis by incorporating into RNA and inhibiting thymidylate synthase.
Inhibition of fungal cell mitosis by binding to microtubules, disrupting spindle formation and nuclear division.
50-150 mg/kg/day orally divided every 6 hours; intravenous dosing: 50-150 mg/kg/day divided every 12 hours.
125 mg orally once daily with a high-fat meal for 7 days, then 125 mg every other day for 7 days (total 13 doses).

Terminal elimination half-life 2.5-6 hours (normal renal function). Prolonged to 30-250 hours in renal impairment (CrCl < 20 mL/min). Half-life correlates with creatinine clearance.
Terminal half-life approximately 9.5 hours; may be prolonged in liver disease.
Primarily renal excretion of unchanged drug (75-90% within 24 hours). Less than 1% eliminated as 5-fluorouracil metabolite. Biliary/fecal excretion negligible.
Primarily hepatic metabolism; <1% excreted unchanged in urine; metabolites excreted in bile and feces.
