Despite ranitidine (zantac) being pulled from market last year, a new study from the FDA did not find evidence that it increases concentrations of the carcinogenic metabolite people were worried about (i.e., it's probably safe). From @JAMA_current https://t.co/AdRic2GdXS

In this crossover, randomized clinical trial, oral ranitidine did not significantly increase 24-hour urinary excretion of NDMA when administered with a noncured-meats diet or a cured-meats diet. https://t.co/EszRvfJOFJ
