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 (CYP51), thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This leads to increased membrane permeability and fungal cell death.
200 mg orally once daily with food.
Intravaginal: 1 applicatorful (100 mg) at bedtime for 3 consecutive nights.

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 elimination half-life is 20-25 hours (intravaginal administration). This long half-life supports a 3-day dosing regimen, maintaining therapeutic concentrations.
Primarily hepatic metabolism; renal excretion of unchanged drug <1%. Biliary/fecal excretion accounts for ~20-35% of metabolites.
Renal: approximately 10-20% as unchanged drug; fecal: >50% as metabolites; biliary: minor route. The majority is eliminated via feces as metabolites, reflecting hepatic metabolism and biliary excretion.
