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.
Vancomycin inhibits cell wall synthesis by binding to the D-alanyl-D-alanine terminus of peptidoglycan precursors, preventing cross-linking.
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.
500-1000 mg orally every 12 hours or 250 mg every 6 hours.

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: 8-12 hours in patients with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
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 (unchanged): 30-50% within 24 hours; Biliary/fecal: 15-25% as metabolites; remainder undergoes hepatic metabolism.
