To protect patients and strengthen the global medicines supply chain, USP is providing tools and solutions to analyze and monitor emerging impurities in the drug supply.
Starting in 2018 the presence of nitrosamine impurities was identified in some angiotensin II receptor blocker (ARBs) used to treat high blood pressure and heart failure. Subsequently, nitrosamines impurities have been found in additional drug products, leading to a major effort by regulators and industry to reduce or eliminate their presence in the drug supply.
Companies are responsible for understanding their manufacturing processes, which includes identifying and preventing the presence of unacceptable impurities. This involves developing new predictive approaches, along with using suitable methods to detect and control these impurities as well as others that may arise when making changes to manufacturing processes.
USP is supporting manufacturers and regulators with tools and solutions for testing, assessing risk and understanding potential sources related to nitrosamine impurities.
