AMBISOME vs VANOBID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amphotericin B binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular contents and fungal cell death.
Vancomycin inhibits cell wall synthesis by binding to the D-alanyl-D-alanine terminus of peptidoglycan precursors, preventing cross-linking.
3-5 mg/kg/day intravenously for systemic fungal infections; for visceral leishmaniasis: 3 mg/kg/day IV on days 1-5, 14, and 21.
500-1000 mg orally every 12 hours or 250 mg every 6 hours.

Terminal elimination half-life: approximately 7–10 hours (initial phase), with a prolonged terminal half-life of 100–153 hours due to slow redistribution from tissues; clinically, this supports once-daily dosing after initial accumulation.
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.
Renal: negligible (<1% unchanged); Biliary/fecal: primary route, approximately 90% of dose recovered in feces as parent drug and metabolites; Urinary: minimal (less than 1% as unchanged drug).
Renal (unchanged): 30-50% within 24 hours; Biliary/fecal: 15-25% as metabolites; remainder undergoes hepatic metabolism.
