NYSTATIN vs SELENIUM SULFIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nystatin binds to sterols in the fungal cell membrane, primarily ergosterol, altering membrane permeability and causing leakage of intracellular components, leading to fungal cell death.
Selenium sulfide is an antifungal and cytostatic agent. It reduces sebum production and inhibits the growth of Malassezia species by interfering with fungal lipid metabolism and cell wall synthesis. The exact molecular mechanism is not fully elucidated.
Oral: 500,000 to 1,000,000 units (5-10 mL suspension) swish and swallow 3-4 times daily; Vaginal: 1 vaginal tablet (100,000 units) once or twice daily; Topical: Apply cream/ointment 2-3 times daily; duration depends on indication.
Topical: 2.5% lotion or shampoo applied to affected area once daily for 7 days; 1% shampoo used once or twice weekly for maintenance.

Due to minimal systemic absorption, a terminal elimination half-life is not clinically relevant. In vitro plasma degradation half-life is approximately 1.5 hours, but this is not applicable in vivo.
Not established; due to negligible systemic absorption, a terminal half-life is not clinically relevant. If absorbed, selenium has a long biological half-life of approximately 65–115 days due to incorporation into selenoproteins.
Nystatin is not absorbed from the gastrointestinal tract after oral administration; virtually 100% of the ingested dose is excreted unchanged in the feces. After topical application, systemic absorption is negligible; any absorbed drug is excreted via bile and feces (<1% renal).
Selenium sulfide is minimally absorbed after topical application. The small absorbed fraction is excreted renally as selenite or selenate, with fecal excretion of unabsorbed drug accounting for >90% of the dose.
