| Analysis Note: | These products are for test and assay use only. They are not meant for administration to humans or animals and cannot be used to diagnose, treat, or cure diseases of any kind. |
| Application: | Nystatin USP reference standard suitable for use in specified USP compendial quality tests and assays. Also used to prepare standard, and system suitability solution for the assay, composition analysis and content uniformity by using liquid chromatography in conjunction with UV detector according to the given below monographs of United States Pharmacopeia (USP): • Nystatin, Neomycin Sulfate, Thiostrepton, and Triamcinolone Acetonide Ointment • Nystatin Oral Suspension • Nystatin |
| Biochem/physiol Actions: | Mode of Action: Nystatin acts by binding to ergosterols in fungal cell membranes, increasing permeability of the membrane, and creating nystatin/ergosterol based ion channels. It also functions as a lipid raft-inhibiting reagent and as membrane associated cholesterol. Antimicrobial spectrum: Nystatin acts against fungi, yeasts and molds. |
| Disclaimer: | Nystatin in tissue culuture media is stable at 37°C for three days. It is also stable in moderately alkaline media. Solutions and aqueous suspensions begin to lose activity soon after preparation, with heat, light, and oxygen accelerating the decomposition. Aqueous suspensions are stable for 10 minutes when heating to 100°C at pH 7. |
| Disclaimer: | Nystatin is soluble at 28°C in methanol (11.2 mg/mL), ethanol (1.2 mg/mL), carbon tetrachloride (1.23 mg/mL), chloroform (0.48 mg/mL), benzene (0.28 mg/mL), and ethylene glycol (8.75 mg/mL). It is also soluble in DMSO at 5 mg/mL and freely soluble in DMF and formamide. It is not recommended to autoclave or sterile filter solutions of Nystatin. Nystatin is also effective as a suspension, stable at 37°C for 3 days. Prepare 50 mg/mL stock suspensions in water and store at -20°C. ? |
| General description: | Nystatin is a polyene antifungal antibiotic produced by Streptomyces noursei. It binds to ergosterol in fungal cell membranes, causing pore formation and leakage of intracellular contents. The USP reference standard is used in microbiological assays to determine potency and confirm identity in nystatin formulations. The USP biologics antibiotics category includes a wide range of antimicrobial agents that are essential in treating bacterial infections. These antibiotics are derived from various natural sources or synthesized to combat specific pathogens effectively. The USP provides comprehensive standards, reference materials, and analytical procedures to ensure the identity, quality, purity, and consistency of antibiotic therapeutics throughout their lifecycle. The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics. |
