isotopically labeled ranitidinehydrochloride confirmed the formation of NDMA solely from an intermolecular reaction of ranitidinehydrochloride without involvement of impurities. Factors that influence the rate of degradation include heat, humidity, and the crystal morphology of ranitidinehydrochloride with the material exhibiting a columnar habit showing a slower rate of degradation.
