Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diflucan (fluconazole) inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This disrupts membrane integrity and function, leading to fungal cell death. At high concentrations, it may also directly damage fungal membranes.
Inhibits fungal CYP450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
200 mg IV loading dose, then 100-200 mg IV once daily; for invasive candidiasis, 800 mg IV loading dose then 400 mg IV once daily.
Topical: Apply twice daily for 2-4 weeks. Vaginal: 200 mg suppository at bedtime for 3 days, or 100 mg suppository at bedtime for 7 days, or 1200 mg suppository as a single dose. Oral (buccal): 50 mg once daily for 14 days.

Terminal elimination half-life is approximately 30 hours (range 20-50 hours) in adults with normal renal function; prolonged to 98 hours in end-stage renal disease, requiring dose adjustment.
Terminal elimination half-life is approximately 24 hours (range 20-40 hours) following intravenous administration. This extended half-life supports twice-daily dosing for systemic infections.
Approximately 80% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 11% is excreted as metabolites in urine; fecal excretion accounts for less than 5%.
Miconazole is primarily metabolized in the liver, with less than 1% of an intravenous dose excreted unchanged in urine. Biliary/fecal elimination accounts for approximately 50% of the dose as metabolites. Renal elimination of metabolites is minimal.
