Zantac Cancer Research Shows Link Between Ranitidine, NDMA and Cancer

What does the latest Zantac cancer research show about the potential link between Zantac (ranitidine) and cancer? Valisure, an online pharmacy that first discovered high levels of probable human carcinogen N-Nitrosodimethylamine (NDMA) in Zantac and its generic equivalents, has rolled out new Zantac NDMA data supporting its initial findings that these popular heartburn medications put patients at increased risk for serious cancers. In its Zantac cancer research study published in the Journal of the American Medical Association (JAMA), Valisure conducted tests to see if NDMA could form from different ranitidine products, including Zantac, under different conditions. Most notably, they looked for whether NDMA could form when Zantac or generic ranitidine was exposed to conditions inside the human body. According to Kaury Kucera, the chief scientific officer for Valisure, “Valisure detected NDMA in every brand and every dosage form of ranitidine that we tested whether over the counter or prescription and regardless of manufacturer.” In an additional study published to MedRxiv, Valisure attempted to verify a correlation between ranitidine product use (or similar H₂-blockers) and certain cancers. This study concluded that “among a cohort of cancer patients reporting use of H₂-blockers or PPIs at the time of diagnosis, we found an association between ranitidine use and cancers of the breast, thyroid, bladder and prostate.”

“We found an association between ranitidine [Zantac] use and cancers.”

More Research Linking NDMA in Zantac to Cancer Cases

Studies dating as far back as 1991 have linked NDMA to the development of cancer, with one study published in the American Association for Cancer Research that showed that rats exposed to NDMA were more likely to develop a liver neoplasm. NDMA is actually used to cause cancer in rats in many lab experiments. Another study published by a Danish cohort found an increased risk for colorectal cancer in individual patients, though studies are still ongoing to confirm this.

“What does this research mean if I’ve taken Zantac or ranitidine?”

There are currently a number of Zantac lawsuits being brought against its manufacturing companies, including U.S.-based Sanofi, that allege these companies knew their product was contaminated with NDMA. NDMA is listed by the FDA as a “probable human carcinogen” meaning it is a substance that could cause cancer in humans. High levels of NDMA in Zantac and ranitidine may cause these types of cancer:

• Bladder cancer
• Colorectal cancer
• Kidney cancer
• Stomach cancer
• Intestinal cancer
• Liver cancer
• Lung cancer
• Thyroid cancer
• Brain cancer
• Throat/nasal cancer
• Ovarian cancer
• Testicular cancer
• Uterine cancer
• Breast cancer
• Esophageal cancer
• Pancreatic cancer
• Prostate cancer
• Leukemia, non-Hodgkins lymphoma, and Multiple Myeloma

These new findings are the most recent in a long line of studies linking Zantac to NDMA contamination and the later development of cancer in many patients. In April 2020, the FDA officially recalled Zantac and other ranitidine products, stating “The agency has determined that the impurity in some ranitidine products increases over time and when stored at higher than room temperatures and may result in consumer exposure to unacceptable levels of this impurity. As a result of this immediate market withdrawal request, ranitidine products will not be available for new or existing prescriptions or OTC use in the U.S.” FEBRUARY 2023 UPDATE: Due to recent developments in the litigation, our firm is no longer accepting Zantac claims.
