In Part 2 of this series we looked at the development of ranitidine (brand name Zantac), its rise as a hugely profitable heartburn drug, and the discovery that the carcinogen NDMA was found in rantidine, eventually leading to its recall and removal from the market. In this Part 3 I discuss how ranitidine can evolve into the cancer-causing chemical NDMA.
Nanitidine Can Form NDMA in the Stomach
When ranitidine enters the stomach, it can interact with “nitrites.” Nitrites are chemicals often found in spicy or salty foods. Food producers add nitrites to certain foods to prolong shelf life. All the way back in 1981, Dr. Silvio de Flora published a study showing that when ranitidine is introduced to nitrites it can lead to “toxic effects.” Dr. de Flora cautioned that if people take ranitidine, they should eat foods low in nitrites and avoid ranitidine near meal times.
