Nystatin Powder stands as a widely recognized and effective polyene antifungal raw material. It is known for its ability to target and combat various mold and yeast infections, including those caused by Candida species. As a crucial ingredient in pharmaceutical and research applications, understanding its properties and uses is essential.

The mechanism of action for Nystatin is well-defined. Similar to other polyene antifungals, it exerts its effect by binding to ergosterol, a sterol that is a major and essential component of the fungal cell membrane. This binding disrupts the integrity of the membrane. When present in sufficient concentrations, Nystatin forms pores within the fungal cell membrane. These pores allow for the leakage of vital intracellular components, particularly potassium ions (K+), leading to the death of the fungal cell. The effectiveness of Nystatin stems from the fact that ergosterol is primarily found in fungi, making the drug relatively safe for use in animals and humans compared to its impact on fungal pathogens.

Nystatin Powder, typically available in specifications such as 98% purity, often presents as a brownish-yellow powder. Its applications are varied and extend beyond just treating established infections. It is frequently employed prophylactically in patients who are at a higher risk of developing fungal infections, helping to prevent their onset.

In clinical settings, Nystatin is prescribed in units, with typical doses varying based on the site of infection. For oral infections, doses might be around 100,000 units, while intestinal infections could require doses up to 1 million units. A significant advantage of Nystatin, particularly when administered orally for gut infections, is that it is not significantly absorbed from the gastrointestinal tract. This low systemic absorption contributes to its safety profile and minimizes potential drug interactions, making it a valuable tool for managing localized fungal issues.

Beyond its direct medical applications, Nystatin is also a valuable reagent in cellular biology research. At concentrations around 3 µg/mL, it acts as an inhibitor of the lipid raft-caveolae endocytosis pathway in mammalian cells. This property makes it useful for scientists studying specific cellular transport mechanisms.

Historically and in specialized contexts, Nystatin has been used to prevent the spread of mold on valuable objects. A notable example includes its application to damaged wood panel paintings after the Arno River Flood in Florence, Italy, in 1966, demonstrating its utility in preservation efforts against fungal decay.

Furthermore, Nystatin serves as an important tool in electrophysiology, specifically in "perforated" patch-clamp recordings. When included in the recording pipette solution, it forms pores in the cell membrane that are permeable predominantly to monovalent ions. This technique allows researchers to measure electrical currents across the cell membrane without disrupting the intracellular contents by excessive dialysis, providing a less invasive method for certain studies.
