Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and lead to leakage of intracellular contents and cell death.
Intravaginal administration of one applicator (200 mg miconazole nitrate) at bedtime for 3 consecutive 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 is approximately 20-30 hours for miconazole after systemic absorption, reflecting slow elimination from deep tissue compartments.
Variable; estimated 2-5 hours for systemic absorption (if any), but negligible systemic levels due to poor absorption.
Approximately 50% of absorbed dose excreted in feces via biliary elimination; <1% excreted unchanged in urine. Unabsorbed drug from vaginal administration is eliminated in vaginal discharge.
Primarily fecal (>95%) as unchanged drug; minimal renal excretion (<1%).
