Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diflucan (fluconazole) inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This disrupts membrane integrity and function, leading to fungal cell death. At high concentrations, it may also directly damage fungal membranes.
Binds to microtubule-associated proteins, disrupting mitotic spindle formation and inhibiting fungal cell division.
200 mg IV loading dose, then 100-200 mg IV once daily; for invasive candidiasis, 800 mg IV loading dose then 400 mg IV once daily.
250 mg orally twice daily for tinea infections; 500 mg orally twice daily for onychomycosis. Administer with a fatty meal to enhance absorption.

Terminal elimination half-life is approximately 30 hours (range 20-50 hours) in adults with normal renal function; prolonged to 98 hours in end-stage renal disease, requiring dose adjustment.
Terminal elimination half-life: 9–24 hours (mean ~16 hours). Clinical context: prolonged half-life allows once-daily dosing; steady-state achieved within 2–3 days.
Approximately 80% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 11% is excreted as metabolites in urine; fecal excretion accounts for less than 5%.
Renal (largely unchanged, <1% as metabolites); biliary/fecal (minor). Approximately 36% of a dose is excreted in urine within 6 hours, and up to 50% within 72 hours.
