NYSTEX vs VANOBID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and lead to leakage of intracellular contents and cell death.
Vancomycin inhibits cell wall synthesis by binding to the D-alanyl-D-alanine terminus of peptidoglycan precursors, preventing cross-linking.
Topical: Apply thin layer to affected area twice daily. Oral suspension (nystatin): 500,000-1,000,000 units (5-10 mL) four times daily for candidiasis. Vaginal tablets: 1 tablet (100,000 units) intravaginally once daily for 14 days.
500-1000 mg orally every 12 hours or 250 mg every 6 hours.

Variable; estimated 2-5 hours for systemic absorption (if any), but negligible systemic levels due to poor absorption.
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.
Primarily fecal (>95%) as unchanged drug; minimal renal excretion (<1%).
Renal (unchanged): 30-50% within 24 hours; Biliary/fecal: 15-25% as metabolites; remainder undergoes hepatic metabolism.
