Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to tubulin, disrupting microtubule function and inhibiting fungal cell mitosis; deposited in keratin precursor cells, making keratin resistant to fungal invasion.
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.
250-375 mg orally once daily or 500-750 mg orally once daily for severe infections.
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.

9-24 hours (mean 15 hours); prolonged in liver disease.
Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
Renal (<1% unchanged); fecal (36% as metabolites); tissue deposition may persist for weeks.
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
