NYSTATIN vs VFEND
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nystatin binds to sterols in the fungal cell membrane, primarily ergosterol, altering membrane permeability and causing leakage of intracellular components, leading to fungal cell death.
Inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Oral: 500,000 to 1,000,000 units (5-10 mL suspension) swish and swallow 3-4 times daily; Vaginal: 1 vaginal tablet (100,000 units) once or twice daily; Topical: Apply cream/ointment 2-3 times daily; duration depends on indication.
IV: Loading dose of 6 mg/kg every 12 hours for 2 doses, then 4 mg/kg every 12 hours. Oral: Weight ≥40 kg: Loading dose of 400 mg every 12 hours for 2 doses, then 200 mg every 12 hours; weight <40 kg: Loading dose of 200 mg every 12 hours for 2 doses, then 100 mg every 12 hours.

Clinical Note
moderateNystatin + Risedronic acid
Due to minimal systemic absorption, a terminal elimination half-life is not clinically relevant. In vitro plasma degradation half-life is approximately 1.5 hours, but this is not applicable in vivo.
Terminal half-life is approximately 24 hours (range 12–30 h) in adults. Prolonged in hepatic impairment (Child-Pugh A: 48 h; B: 72 h).
Nystatin is not absorbed from the gastrointestinal tract after oral administration; virtually 100% of the ingested dose is excreted unchanged in the feces. After topical application, systemic absorption is negligible; any absorbed drug is excreted via bile and feces (<1% renal).
Primarily hepatic metabolism; <2% excreted unchanged in urine. Fecal excretion accounts for ~80% of metabolites. Renal excretion of unchanged drug is negligible.
