ABSTRACT
The concept of extractables and leachable has introduced a new era for identifying potential impurities in drug products. Pharmaceutical packaging materials encompass a variety of polymers due to their appealing properties for storing the drug product. However, numerous chemical species may leach into the drug product from these polymers, posing significant health hazards in the public domain. Identifying such leachable is crucial for assessing safety and addressing toxicological concerns. Acrylic acids are commonly used materials for adhering needles to the barrel in pre-filled syringes. In this study, we identified acrylic acid leachable impurities in ganirelix drug products available in the market using mass spectrometry as an analytical technique. These impurities leached into the drug product during storage conditions. Characterization of the impurities was carried out through data obtained from HRMS and MS/MS analysis, revealing them as polyacrylic acid-ganirelix adduct impurities. This study offers valuable insights into identifying leachable and susceptible sites, providing a foundation for potential modifications in similar classes of drug products, thereby enhancing their safety and efficacy.
