MONISTAT vs NILSTAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole, the active ingredient in MONISTAT, inhibits fungal CYP51 (lanosterol 14-alpha-demethylase), blocking ergosterol synthesis and disrupting fungal cell membrane integrity, leading to cell death.
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.
Intravaginal: 200 mg suppository at bedtime for 3 days, or 100 mg suppository at bedtime for 7 days, or 2% cream 5 g intravaginally at bedtime for 7 days. Topical: Apply 2% cream twice daily for 2-4 weeks.
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.

Approximately 90-120 minutes; supports twice-daily local dosing.
Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
Primarily fecal (approximately 90%) as unchanged drug; less than 2% renal elimination.
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
