NYSERT vs NYSTATIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
NYSERT is a fixed-dose combination of nystatin and sertaconazole. Nystatin, a polyene antifungal, binds to ergosterol in fungal cell membranes, disrupting permeability and causing cell death. Sertaconazole, an azole antifungal, inhibits lanosterol 14α-demethylase (CYP51), blocking ergosterol synthesis and accumulation of toxic methylsterols. Synergistic action provides broad-spectrum antifungal activity against Candida spp. and dermatophytes.
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.
10 mg orally once daily at bedtime, with or without food.
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.

Terminal elimination half-life approximately 20-25 hours in healthy adults; prolonged in hepatic impairment (up to 40 hours) and in elderly patients.
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.
Primarily hepatic metabolism (CYP3A4) followed by biliary excretion of metabolites; ~60% fecal, ~30% renal (as metabolites), <5% unchanged in urine.
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).
