Ranitidine is Safe.NDMA levels found in ranitidine are similar to the levels found in common foods
Excerpts from the USFDA statement
USFDA TESTS :-
NDMA (N-Nitrosodimethylamine) found in ranitidine are similar to the levels like common foods(like grilled or smoked meats etc) says USFDA.
USFDA also conducted tests that stimulate stomach environment to check what happens to ranitidine if exposed to acid in the stomach with a normal diet, Results indicate, NDMA is not formed through this process.
If ranitidine is exposed to a simulated small intestine environment, NMDA is not formed.
USFDA also developed a stimulated gastric fluid(SGF) model to be used with the LC-MS testing method. The results of these tests showed no additional NDMA generated in the stomach.
USFDA ON TESTS BY THIRD PARTY
NDMA observed through FDA testing are much lower than the levels some third-party scientists first claimed
SETS PERMISSIBLE LIMITS
USFDA sets NDMA linits;Consuming up to 0.096 microgrmas(96nanogram) or 0.32 parts per milion(ppm) of NDMA per days is considered reasonably safe for human ingestion based on lifetime exposure. This is based on methods described in the 2018 ICH guidance M7(R1) Assessment and control of DNA reactive (mutagenic) impurities in pharmaceuticals to limit potential carcinogenic risk.
WHY IS IT NOT A MATTER OF WORRY?
As per 2018 ICH Guidance M7(R1), If people consume 96 nanogram of NDMA daily for 70 years, the probable risk of cancer would be 1 in 100,000 patients.
Only if NDMA levels in ranitidine are above the acceptable limits (96 nanograms per day or 0.32 ppm) USFDA is asking companies to voluntarily recall ranitidine batches. If within permissible limits, need or recall and safe.
Several brands/companies have started selling and realunching Ranitidine in USA.
