MYCOSTATIN vs NYSTOP
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, leading to leakage of intracellular ions 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.
Apply a thin layer to affected area 2-3 times daily or as directed. Nystatin is not absorbed systemically; topical use only.

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.
Not applicable for systemic pharmacokinetics due to minimal absorption; local half-life on mucosal surfaces is not defined. For intravenous administration (not approved), the terminal half-life is approximately 2-4 hours, but this route is not clinically used.
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%).
Nystatin is not absorbed from the gastrointestinal tract or intact skin/mucous membranes; when administered topically or orally, it is excreted almost entirely in feces as unchanged drug (>99%). Less than 1% is excreted renally if ingested. No quantified biliary excretion reported.
