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.
Posaconazole inhibits fungal CYP450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
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.
300 mg (one 300-mg vial) intravenously twice on day 1, then 300 mg intravenously once daily starting on day 2. Alternatively, oral suspension: 200 mg (10 mL) three times daily. For prophylaxis, IV: 300 mg twice on day 1, then 300 mg once daily; oral: 200 mg three times daily.

Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
The terminal elimination half-life is approximately 27 hours (range 20-66 hours) in healthy subjects, allowing for once-daily dosing after steady state.
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
Posaconazole is primarily excreted in the feces (77%) as unchanged drug, with renal excretion accounting for 14% of the dose (primarily as glucuronide conjugates). Less than 0.2% is excreted unchanged in urine.
