Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits squalene epoxidase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Clotrimazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing membrane permeability.
1% cream applied topically once daily for 2 weeks for tinea pedis, 1 week for tinea corporis/cruris.
Clotrimazole 100 mg vaginal tablet inserted intravaginally once daily for 7 days or 200 mg once daily for 3 days; or 500 mg single dose. Also available as 1% vaginal cream, 1 applicatorful (5 g) intravaginally once daily for 7-14 days.

Terminal elimination half-life is approximately 35–40 hours following topical application; long half-life supports once-daily dosing.
Biphasic: initial half-life ~30 minutes, terminal half-life ~30 hours; clinical significance: supports once-daily dosing for topical/vaginal formulations.
Primarily metabolized in the liver; minimal excretion of unchanged drug. Less than 5% of a topical dose is absorbed systemically; excreted in urine and feces as metabolites.
Primarily hepatic metabolism; about 80-90% of dose excreted as metabolites in feces via biliary excretion, less than 1% unchanged in urine.
