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.
Miconazole inhibits fungal cytochrome P450 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.
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 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.
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.
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 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.
