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, 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.
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.
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 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: 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.
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%.
Fecal: Approximately 90% of absorbed dose; Renal: <2% as unchanged drug; Biliary: Minor, less than 10%.
