In addition, the study discarded all stomach samples that contained ranitidine because they could have “falsely high” concentrations of nitrosamines, so any NDMA produced by the breakdown of ranitidine would not have been detected. For example, processes that involve alkylamines, which are naturally occurring and man-made compounds found in the environment, may produce NDMA via chemical reaction. In the case of ARBs, the FDA has recommended numerous recalls as it discovered unacceptable levels of nitrosamines. … However, all Zantac and ranitidine products have been recalled as of April 2020.
