Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to ergosterol in fungal cell membranes, forming pores that increase permeability, leading to leakage of intracellular contents and cell death.
Clotrimazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing membrane permeability.
IV: 0.25-1 mg/kg/day as a single infusion; for aspergillosis, up to 1.5 mg/kg/day; maximum daily dose 1.5 mg/kg.
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 15 days (range 10-20 days) after a single dose; with prolonged therapy, a prolonged terminal half-life of up to 15 days reflects slow redistribution from tissue depots.
Biphasic: initial half-life ~30 minutes, terminal half-life ~30 hours; clinical significance: supports once-daily dosing for topical/vaginal formulations.
Primarily fecal (40-50%) via biliary elimination without metabolism; renal excretion of unchanged drug is minimal (<5% in 24 hours).
Primarily hepatic metabolism; about 80-90% of dose excreted as metabolites in feces via biliary excretion, less than 1% unchanged in urine.
