Article Synopsis
  • The study investigates the presence of nitrosamine-related impurities and AZBT in sartan medications, classifying them as human mutagens and carcinogens based on long-term treatment effects.
  • A new, efficient method was developed for simultaneous quantification of these impurities using reversed-phase liquid chromatography combined with tandem mass spectrometry.
  • The method showed high extraction efficiency, wide linear range, and strong recovery rates, and was applied to analyze 16 losartan samples, finding AZBT in some but no nitrosamine impurities in any.
