| General description: | Chlortetracycline hydrochloride is a first-generation tetracycline antibiotic with activity against a wide spectrum of bacteria. It functions by preventing aminoacyl-tRNA attachment to the bacterial ribosome. The USP standard aids in identity verification and quantitative assay testing. 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. |
