Beschreibung

General description

Erythromycin is a macrolide antibiotic produced by Saccharopolyspora erythraea, acting by inhibition of protein synthesis at the 50S ribosomal subunit. It is used to treat a variety of infections caused by susceptible organisms. The USP standard provides quality benchmarks for identification, assay, and dissolution studies in erythromycin 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.

Application

Erythromycin USP reference standard, intended for use in specified quality tests and assays as specified in the USP compendia. Also, for use with USP monographs such as:

• Erythromycin Stearate
• Erythromycin Ethylsuccinate
• Erythromycin Lactobionate for Injection
• Erythromycin Ointment
• Erythromycin Pledgets
• Erythromycin Injection
