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 nitrate, an imidazole antifungal, 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.
One vaginal suppository (200 mg miconazole nitrate) intravaginally at bedtime for 3 consecutive days; or one applicatorful (5 g) of 4% vaginal cream intravaginally at bedtime for 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 is approximately 30 hours after topical vaginal application; prolonged in hepatic impairment.
Primarily renal excretion of unchanged drug (75-90% within 24 hours). Less than 1% eliminated as 5-fluorouracil metabolite. Biliary/fecal excretion negligible.
Primarily fecal (97%) via biliary excretion; renal excretion of unchanged drug is negligible (<1%).
