DIFLUCAN vs MICONAZOLE NITRATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diflucan (fluconazole) is a triazole antifungal agent that inhibits fungal cytochrome P450 14-alpha-demethylase, thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This leads to increased membrane permeability and inhibition of fungal growth.
Inhibits fungal CYP450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Oral or IV: 200-400 mg loading dose, then 100-200 mg once daily. Dose and duration depend on indication.
Topical: Apply twice daily for 2-4 weeks. Vaginal: 200 mg suppository at bedtime for 3 days, or 100 mg suppository at bedtime for 7 days, or 1200 mg suppository as a single dose. Oral (buccal): 50 mg once daily for 14 days.

30 hours (range 20-50 hours); prolonged in renal impairment (up to 98 hours in CrCl <20 mL/min)
Terminal elimination half-life is approximately 24 hours (range 20-40 hours) following intravenous administration. This extended half-life supports twice-daily dosing for systemic infections.
Renal: 80% unchanged; fecal/biliary: 11% as metabolites
Miconazole is primarily metabolized in the liver, with less than 1% of an intravenous dose excreted unchanged in urine. Biliary/fecal elimination accounts for approximately 50% of the dose as metabolites. Renal elimination of metabolites is minimal.
