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. Tioconazole, also an imidazole, similarly inhibits ergosterol synthesis.
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: One applicatorful of 6.5% miconazole nitrate cream (1200 mg) at bedtime as a single dose. Topical: Apply 2% miconazole nitrate cream to affected area twice daily for 2 weeks.

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.
The terminal elimination half-life of miconazole following intravenous administration is approximately 24 hours (range 20-30 hours). This supports once-daily dosing for systemic infections, though topical application yields negligible systemic absorption.
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%.
Approximately 90% of an absorbed dose is eliminated in feces as unchanged drug and metabolites; less than 1% is excreted renally as unchanged drug. Biliary excretion is the primary route for the absorbed fraction.
