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.
Clotrimazole, an imidazole antifungal, inhibits cytochrome P450 14α-demethylase (CYP51), thereby blocking ergosterol synthesis in fungal cell membranes, increasing membrane permeability and causing cell death. Miconazole, also an imidazole, similarly inhibits CYP51, disrupting ergosterol synthesis.
200 mg orally once daily with food.
Clotrimazole vaginal cream 1%: one applicatorful (approximately 5 g) intravaginally at bedtime for 7 consecutive days. Clotrimazole vaginal tablets 100 mg: one tablet intravaginally at bedtime for 7 consecutive days.

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.
Topical clotrimazole has a terminal elimination half-life of 3-6 hours; systemic absorption is minimal, so half-life is not clinically relevant for local effects.
Primarily hepatic metabolism; renal excretion of unchanged drug <1%. Biliary/fecal excretion accounts for ~20-35% of metabolites.
Clotrimazole is primarily excreted via feces (approximately 65%) as metabolites and unchanged drug; renal excretion accounts for less than 1% after topical administration. Biliary excretion is negligible.
