It is now believed in the scientific community that the Zantac (ranitidine) molecule breaks down in the body to form N-Nitrosodimethylamine (known as NDMA). The World Health Organization (WHO) calls NDMA a “potent carcinogen” and has published this paper about the dangers of ingesting NDMA:
The Federal Agency for Toxic Substances has published this public health paper on NDMA:
Studies have shown that the NDMA in your body as a result of taking Zantac (ranitidine) is many times higher than what is considered safe for humans. This lead to the world-wide recall of the drug.
