Vinorelbine is an anti-cancer drug used in the treatment of lung cancer and breast cancer. However, during the manufacturing process, impurities may be formed which can affect the quality, safety, and efficacy of the drug. These impurities can be organic or inorganic in nature and their presence needs to be monitored and controlled within acceptable limits to ensure the purity of the final drug product. Analytical methods are used to detect and quantify these impurities, and appropriate measures are taken to minimize their formation during the manufacturing process.
