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.
Insert one miconazole nitrate 200 mg vaginal suppository intravaginally once daily at bedtime for 3 consecutive days. Apply intravaginal cream as needed for symptom relief.

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.
After intravenous administration, the terminal elimination half-life is approximately 20-24 hours; after topical or intravaginal administration, systemic absorption is minimal, with a terminal half-life of 8-12 hours.
Primarily renal excretion of unchanged drug (75-90% within 24 hours). Less than 1% eliminated as 5-fluorouracil metabolite. Biliary/fecal excretion negligible.
Miconazole is primarily eliminated via hepatic metabolism with biliary excretion of metabolites; <1% of unchanged drug is excreted renally. Fecal elimination accounts for approximately 20-30% of the dose.
