Authenticating drugs with edible microtags On-dose authentication, such as edible microtags, is a relatively new market that has been quietly developing but has the capability to provide new forms of anti-counterfeiting tools. Most of the authentication formats in use today are packaging-oriented, but many of these are proving inadequate as counterfeiters become more sophisticated and more accustomed to traditionally-used authentication technologies. As such, attention has now turned to on-dose technologies; for instance, ARmark Authentication Technologies and Colorcon have developed covert microtags, and Capsugel has licensed a technology that uses nanoembossing from NanoGuardian (a division of NanoInk). Last summer, the FDA issued draft guidance entitled “Incorporation of Physical-Chemical Identifiers (PCIDs) into Solid Oral Dosage Form Drug Products for Anti-Counterfeiting”, which both validates industry interest in on-dose technologies and calls for the use of safe and well-studied food additives when using such technologies. spectrum can also be linked to (and verified by) other information printed on the package. Thanks to the maturity of the Manufacturing microtags silicon wafer industry, Edible microtags made of silica microtags silica, which has been safely can be produced Mike O’Neil used as an ingredient in inexpensively using TruTag Technologies food and drugs for decades the electrochemical at a limit of up to 2% by etch of a silicon weight, can be applied in or on an wafer and then heating the silicon. individual unit dose to help identify, Importantly, as no modifications to authenticate and ensure the quality existing manufacturing processes of a medicinal product.

This confidence that can be used for quality assurance applications, returns monitoring and anti-counterfeiting purposes. Consumers in particular should also welcome new technologies that help ensure their health and safety, especially those that are based on well-studied and accepted materials.
