Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clotrimazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, thereby disrupting ergosterol biosynthesis and compromising fungal cell membrane integrity.
Inhibits fungal CYP51 (lanosterol 14α-demethylase), blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
For oropharyngeal candidiasis: Clotrimazole troche 10 mg dissolved slowly in mouth 5 times daily for 14 days. For vulvovaginal candidiasis: Clotrimazole vaginal tablet 500 mg single dose or 200 mg daily for 3 days or 100 mg daily for 7 days; 1% vaginal cream 5 g intravaginally daily for 7-14 days.
Ketoconazole 200 mg orally once daily with food. For severe infections, increase to 400 mg once daily. Duration depends on indication.

Terminal elimination half-life is 20-50 hours (mean ~30 hours) in adults; prolonged in neonates (~40-80 hours) and in hepatic impairment.
Biphasic elimination: initial half-life ~2 hours, terminal half-life 6–10 hours in adults with normal hepatic function; prolonged in hepatic impairment.
Primarily hepatic metabolism; <1% excreted unchanged in urine; ~50% of dose excreted in feces as metabolites.
Approximately 70% of the dose is excreted unchanged in feces via biliary elimination, and about 20–35% is excreted in urine, with less than 1% as unchanged drug in urine.
