Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This disrupts membrane integrity and leads to fungal cell death. Miconazole also has direct anti-inflammatory and antibacterial properties.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and lead to leakage of intracellular contents and cell death.
Miconazole nitrate 1200 mg vaginal suppository inserted intravaginally once at bedtime; plus external miconazole nitrate 2% cream applied to affected area twice daily for up to 7 days.
Topical: Apply thin layer to affected area twice daily. Oral suspension (nystatin): 500,000-1,000,000 units (5-10 mL) four times daily for candidiasis. Vaginal tablets: 1 tablet (100,000 units) intravaginally once daily for 14 days.

Terminal elimination half-life: 24-30 hours (range 20-50 hours). Clinical context: Once-daily dosing may be considered for some indications, but prolonged half-life supports weekly or twice-weekly regimens for systemic infections.
Variable; estimated 2-5 hours for systemic absorption (if any), but negligible systemic levels due to poor absorption.
Fecal: Approximately 90% of absorbed dose; Renal: <2% as unchanged drug; Biliary: Minor, less than 10%.
Primarily fecal (>95%) as unchanged drug; minimal renal excretion (<1%).
