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.
Griseofulvin binds to tubulin and disrupts microtubule function, inhibiting fungal cell division and nucleic acid synthesis.
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.
500 mg orally once daily or 250 mg orally twice daily; for severe infections, 500 mg twice daily or 250 mg three times daily. Maximum daily dose: 1 g. Administer with or after meals.

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 ranges from 6.5 to 9 hours (mean ~7.5 hours) in patients with normal hepatic function; prolonged in hepatic impairment.
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; less than 1% excreted unchanged in urine; approximately 30-50% of a dose is eliminated in feces as metabolites, with minor biliary excretion.
