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.
Miconazole inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
50-150 mg/kg/day orally divided every 6 hours; intravenous dosing: 50-150 mg/kg/day divided every 12 hours.
Intravaginal administration of one applicator (200 mg miconazole nitrate) at bedtime for 3 consecutive days.

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 elimination half-life is approximately 20-30 hours for miconazole after systemic absorption, reflecting slow elimination from deep tissue compartments.
Primarily renal excretion of unchanged drug (75-90% within 24 hours). Less than 1% eliminated as 5-fluorouracil metabolite. Biliary/fecal excretion negligible.
Approximately 50% of absorbed dose excreted in feces via biliary elimination; <1% excreted unchanged in urine. Unabsorbed drug from vaginal administration is eliminated in vaginal discharge.
