Molecular Isotope Technologies (MIT LLC) contributes to the mitigation of identity theft of both the pharmaceutical products and the synthetic pathways by which they were produced via Pharmaceutical Product and Process Authentication. Identity theft or counterfeiting, countertrading, and illegal reimportation of pharmaceutical products variously threaten consumer confidence and product efficacy, as well as the economic well-being of pharmaceutical companies. Recent studies of the natural stable-isotopic "fingerprints" of pharmaceuticals show a highly-specific method for product monitoring that will allow product and process identification and suppress the perils of identity fraud.
