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 and disrupts fungal mitotic spindle formation, thereby inhibiting fungal cell division. It also interferes with fungal 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 (non-microsize formulation) or 250 mg twice daily; typical duration is 4-8 weeks for tinea capitis, 2-6 weeks for tinea corporis, 4-6 weeks for tinea pedis.

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: 9–24 hours. Clinical context: Steady-state achieved in 2–5 days; 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%.
Renal (1% unchanged), fecal (33% as metabolites), biliary (minor). Extensive hepatic metabolism; <1% excreted unchanged in urine.
