New Method Developed to Detect N-Nitrosamines in Pharmaceuticals
April 19th 2023Sartans are important drugs that help treat hypertension and heart failure. However, since their recall in 2018 because of the presence of genotoxic impurities in these drugs, researchers are tackling the question of how to detect these impurities in these drugs before they go to market. This article describes a HPLC–APCI-MS/MS method that can help in this endeavor.
