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 azole antifungal, inhibits fungal cytochrome P450 14α-demethylase, thereby 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.
ORAVIG (miconazole) 50 mg buccal tablet applied once daily to the upper gum region (canine fossa) for 14 consecutive days. The tablet is placed with the rounded side against the gum and held in place for 30 seconds to ensure adhesion.

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, supporting once-daily buccal administration for sustained local oropharyngeal concentrations.
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 fecal (approximately 52%) with 39% of the dose recovered in urine; less than 0.5% of the dose is excreted unchanged in urine.
