MYCOSTATIN vs NYSTEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mycostatin (nystatin) is a polyene antifungal antibiotic that binds to ergosterol in the fungal cell membrane, forming pores that increase membrane permeability, leading to leakage of intracellular contents and cell death.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and lead to leakage of intracellular contents and cell death.
Nystatin suspension: 400,000-600,000 units (4-6 mL) orally four times daily for 7-14 days. Nystatin pastilles: 200,000-400,000 units (1-2 pastilles) orally four to five times daily for 7-14 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.

Not applicable (nystatin is not absorbed systemically; no meaningful plasma half-life exists). For reference, if absorbed, the terminal half-life would be approximately 4-6 hours, but this is not clinically relevant.
Variable; estimated 2-5 hours for systemic absorption (if any), but negligible systemic levels due to poor absorption.
Nystatin is not absorbed from the gastrointestinal tract, skin, or mucous membranes. After oral administration, virtually all of the drug is excreted unchanged in feces. Renal excretion is negligible (<0.1%).
Primarily fecal (>95%) as unchanged drug; minimal renal excretion (<1%).
