Cefditoren is a broad-spectrum antibiotic used to treat bacterial infections. As with any pharmaceutical product, impurities can be present in the drug substance or drug product. Cefditoren impurities may include degradation products, starting materials, and by-products formed during the manufacturing process. Impurities can affect the stability and efficacy of the drug and must be monitored and controlled to ensure patient safety and product quality. Analytical methods are used to identify and quantify impurities, and regulatory agencies set limits on their acceptable levels.
