FDA on 13/09/2019 alerted patients and health care professionals to Glenmark Pharmaceutical Inc.’s voluntary recall of prescription ranitidine tablets (150 mg and 300 mg). The medicines are being recalled because they may contain unacceptable levels of N-nitrosodimethylamine (NDMA). FDA has advised companies on 17/12/2019 to recall their ranitidine if testing shows levels of NDMA above the acceptable daily intake (96 nanograms per day or 0.32 parts per million for ranitidine). The agency posted the results of its testing of ranitidine samples and has asked companies to conduct their own laboratory testing. Patients taking prescription ranitidine who wish to stop should talk to their health care professional about other treatment options. Multiple drugs are approved for the same or similar uses as ranitidine. FDA recalled the impured Ranitidine, but what about the human consumers who ate the carcinogenic impured Ranitidine by paying to Pharma companies?

Ranitidine is an over-the-counter (OTC) and prescription drug. Ranitidine is an H2 (histamine-2) blocker, which decreases the amount of acid created by the stomach. Over-the-counter ranitidine is approved to prevent and relieve heartburn associated with acid ingestion and sour stomach. Prescription ranitidine is approved for multiple indications, including treatment and prevention of ulcers of the stomach and intestines and treatment of gastroesophageal reflux disease.
Ranitidine Hydrochloride (Zantac tablet) approved by the US FDA on 29/10/1999. Approval was given to Glaxo Wellcome Research and Development.
As the FDA and other agencies around the world continue to investigate ranitidine, more details will become available. In the meantime, the FDA is not calling for individuals to stop taking the medication. However, for many conditions, ranitidine is only recommended for short-term use. If you have been using ranitidine for a while, now would be a good time to discuss with your physician whether you still need it and whether you might benefit from alternative treatment options, including other drug classes or a different H2 blocker.
NDMA is classified as a probable human carcinogen (a substance that could cause cancer) based on results from laboratory tests. NDMA is a known environmental contaminant typically found in water and foods, including meats, dairy products, and vegetables.

Pharmaceutical companies paying millions of salaries every month to employers from the top-level scientist to the bottom level workers.
