NILSTAT vs NYSERT
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 cause leakage of intracellular contents, leading to fungal cell death.
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.
Topical: Apply 100,000 units/g cream or ointment to affected area twice daily. Oral suspension: 100,000 units/mL; 4-6 mL swish and swallow four times daily for 14 days. Oral tablets: 500,000 units; 1-2 tablets three times daily.
10 mg orally once daily at bedtime, with or without food.

Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
Terminal elimination half-life approximately 20-25 hours in healthy adults; prolonged in hepatic impairment (up to 40 hours) and in elderly patients.
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
Primarily hepatic metabolism (CYP3A4) followed by biliary excretion of metabolites; ~60% fecal, ~30% renal (as metabolites), <5% unchanged in urine.
