Lately, there have been wave upon wave of recalled medicine since FDA has been starting doing an investigation on present of problematic human carcinogen substance which is NDMA in mostly common prescribed drug such as Ranitidine. The latest news has mentioned that Glucophage (Metformin) has been suspected to have NDMA as well. Why do you think that this finding was not discovered before, and we have only recently started to hear about this critical threat that exists in mostly used medications?. Is it because pharmaceutical companies have started to not follow strictly Good Manufacturing Practice (GMP) ?
