Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Posaconazole inhibits fungal CYP450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Vancomycin inhibits cell wall synthesis by binding to the D-alanyl-D-alanine terminus of peptidoglycan precursors, preventing cross-linking.
300 mg (one 300-mg vial) intravenously twice on day 1, then 300 mg intravenously once daily starting on day 2. Alternatively, oral suspension: 200 mg (10 mL) three times daily. For prophylaxis, IV: 300 mg twice on day 1, then 300 mg once daily; oral: 200 mg three times daily.
500-1000 mg orally every 12 hours or 250 mg every 6 hours.

The terminal elimination half-life is approximately 27 hours (range 20-66 hours) in healthy subjects, allowing for once-daily dosing after steady state.
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.
Posaconazole is primarily excreted in the feces (77%) as unchanged drug, with renal excretion accounting for 14% of the dose (primarily as glucuronide conjugates). Less than 0.2% is excreted unchanged in urine.
Renal (unchanged): 30-50% within 24 hours; Biliary/fecal: 15-25% as metabolites; remainder undergoes hepatic metabolism.
