Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole nitrate inhibits fungal lanosterol 14α-demethylase (CYP51), disrupting ergosterol synthesis and causing fungal cell membrane damage.
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.
Intravaginally, one suppository (100 mg miconazole nitrate) once daily at bedtime for 7 days or one suppository (200 mg) once daily for 3 days, combined with topical application of miconazole nitrate cream (2%) to the vulvar area twice daily for 7 days.
1 tablet (nystatin 100,000 units) orally three times daily after meals. Each tablet should be allowed to dissolve slowly in the mouth.

Terminal elimination half-life is approximately 20-25 hours, but can be prolonged to 30-40 hours in patients with hepatic impairment.
Plasma half-life is not measurable due to negligible systemic absorption. Topical or oral administration results in local action only; no systemic half-life is clinically relevant.
Primarily fecal (biliary) as unchanged drug and metabolites (~50-60%); renal excretion accounts for <20% of the dose, mostly as inactive metabolites.
Nystatin is not absorbed from the gastrointestinal tract, intact skin, or mucous membranes. After oral administration, it is excreted almost entirely unchanged in feces (over 99%). Minimal renal excretion occurs (less than 1%).
