General description

Oxytetracycline is a broad-spectrum tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. It is effective against a range of Gram-positive and Gram-negative organisms. The USP reference standard ensures assay precision and identity confirmation in oxytetracycline drug products.

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

Oxytetracycline 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:
  • Oxytetracycline Hydrochloride
  • Oxytetracycline Injection
  • Oxytetracycline Tablets
  • Oxytetracycline for Injection
  • Oxytetracycline Hydrochloride Capsules
  • Oxytetracycline Hydrochloride Soluble Powder

Biochem/physiol Actions

Antibiotic produced by Streptomyces rimosus.
Mode of Action: Inhibits protein synthesis (elongation) by preventing binding of aminoacyl-tRNA to the 30S subunit.
Antimicrobial spectrum: Gram-negative and Gram-positive bacteria.
Mode of Resistance: Active efflux, ribosome protection, tetracycline inactivation.

From a genetic standpoint, Streptomyces rimosus is arguably the best-characterized industrial streptomycete as the producer of oxytetracycline and other tetracycline antibiotics. Although resistance to these antibiotics has reduced their clinical use in recent years, tetracyclines have an increasing role in
