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, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, reducing 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.
Intravaginal administration of 100 mg miconazole nitrate suppository once daily at bedtime for 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 is approximately 24-30 hours following intravaginal administration; clinical significance: supports once-daily dosing.
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%.
Primarily via feces (approximately 87-93% of dose) as unchanged drug and metabolites; renal excretion negligible (<1%).
