Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ketoconazole is an imidazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This leads to increased membrane permeability and cell death.
Miconazole inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
200 mg orally once daily with food.
Miconazole nitrate 100 mg vaginal suppository inserted once daily at bedtime for 3 days; or 200 mg vaginal suppository once daily at bedtime for 3 days; or 1200 mg vaginal suppository as a single dose.

Terminal elimination half-life is approximately 2 hours (range 1.5–3.5 hours). Clinically, duration of antifungal effect extends beyond plasma half-life due to persistent tissue levels.
Terminal half-life approximately 24 hours; supports once-daily dosing.
Primarily hepatic metabolism; renal excretion of unchanged drug <1%. Biliary/fecal excretion accounts for ~20-35% of metabolites.
Primarily fecal (90%) as unchanged drug; renal excretion minimal (<1%).
