DIFLUCAN vs MICONAZOLE 7 COMBINATION PACK
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.
Miconazole is an imidazole antifungal agent that inhibits the synthesis of ergosterol, a key component of fungal cell membranes, by inhibiting the enzyme lanosterol 14α-demethylase. This leads to increased membrane permeability and leakage of cellular contents, resulting in fungal cell death.
Oral or IV: 200-400 mg loading dose, then 100-200 mg once daily. Dose and duration depend on indication.
Miconazole 200 mg vaginal suppository once daily at bedtime for 7 days, plus miconazole 2% cream applied intravaginally once daily at bedtime for 7 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 24-30 hours after systemic absorption. Clinically, this supports once-daily dosing for the vaginal route.
Renal: 80% unchanged; fecal/biliary: 11% as metabolites
Miconazole is primarily metabolized in the liver, with metabolites and unchanged drug excreted in feces (50-70%) and urine (10-20%). Biliary excretion is a minor route.
