Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal cytochrome P450 14α-demethylase (CYP51), thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This leads to increased membrane permeability, leakage of cellular contents, and fungal cell death.
Miconazole nitrate, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
For vaginal candidiasis: 200 mg (one suppository) intravaginally at bedtime for 3 consecutive days.
One vaginal suppository (200 mg miconazole nitrate) intravaginally at bedtime for 3 consecutive days; or one applicatorful (5 g) of 4% vaginal cream intravaginally at bedtime for 7 days.

Terminal half-life is approximately 24 hours (range 20-30 hours) following topical vaginal application; prolonged in hepatic impairment.
Terminal elimination half-life is approximately 30 hours after topical vaginal application; prolonged in hepatic impairment.
Primarily hepatic metabolism; <1% excreted unchanged in urine; fecal elimination accounts for ~50% of metabolites.
Primarily fecal (97%) via biliary excretion; renal excretion of unchanged drug is negligible (<1%).
