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.
Inhibition of fungal cell mitosis by binding to microtubules, disrupting spindle formation and nuclear 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.
125 mg orally once daily with a high-fat meal for 7 days, then 125 mg every other day for 7 days (total 13 doses).

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 half-life approximately 9.5 hours; may be prolonged in liver disease.
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%.
Primarily hepatic metabolism; <1% excreted unchanged in urine; metabolites excreted in bile and feces.
