2016 โ A Mitch study in 2016 tested urine samples of 10 people, 5 males and 5 females, who took a single 150 mg ranitidine tablet. They found NDMA levels higher than the FDA limits. Their urine was tested 24 hours before taking ranitidine and then 24 hours after. The study found that the levels of NDMA in the urine increased by 430 times (an average of 47,600 ng per person). The levels were 495 times the FDA daily limit of 95 ng.
