PEG codes used as anti-counterfeit marker in pharma

Researchers in Germany have developed an on-dose marker technology based on polyethylene glycols (PEGs), a commonly used pharma excipient.

The team describe a technique in which they incorporated combinations of PEGs within the coating of tablets to create a unique code that can be used to authenticate the dose using a liquid chromatography/mass spectrometry (LC-MS/MS) method.
