Abstract:
Although the secondary packing materials do not directly contact the finished drug products, compound migration may still happen between them. To ensure drug quality and safety, extractables and leachables of the packing materials should be analyzed. In this study, 2,6-di-tert-butyl-4-methylphenol (BHT) was first found in the labels for pharmaceutical packaging. For the identification of the compound, a strategy combining high performance liquid chromatography (HPLC), ultra-performance liquid chromatography-quadrupole time-of-flight mass (UPLC-Q-TOF-MS) and nuclear magnetic resonance (NMR) spectroscopy was utilized. Afterwards, a effective and sensitive HPLC method for quantification of BHT was developed and validated. Finally, a toxicological risk assessment of BHT was performed to ensure the safety of drugs.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
