MONISTAT 3 vs NYSTAFORM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole nitrate, an imidazole antifungal, 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 cause leakage of intracellular contents, leading to fungal cell death.
One vaginal suppository (200 mg miconazole nitrate) intravaginally at bedtime for 3 consecutive days; or one applicatorful (5 g) of 4% vaginal cream intravaginally at bedtime 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 30 hours after topical vaginal application; prolonged in 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 (97%) via biliary excretion; renal excretion of unchanged drug is negligible (<1%).
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%).
