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, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This disrupts membrane integrity and leads to fungal cell death. Miconazole also has direct anti-inflammatory and antibacterial properties.
50-150 mg/kg/day orally divided every 6 hours; intravenous dosing: 50-150 mg/kg/day divided every 12 hours.
Miconazole nitrate 1200 mg vaginal suppository inserted intravaginally once at bedtime; plus external miconazole nitrate 2% cream applied to affected area twice daily for up to 7 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: 24-30 hours (range 20-50 hours). Clinical context: Once-daily dosing may be considered for some indications, but prolonged half-life supports weekly or twice-weekly regimens for systemic infections.
Primarily renal excretion of unchanged drug (75-90% within 24 hours). Less than 1% eliminated as 5-fluorouracil metabolite. Biliary/fecal excretion negligible.
Fecal: Approximately 90% of absorbed dose; Renal: <2% as unchanged drug; Biliary: Minor, less than 10%.
