Modern Authentication of Pharmaceuticals Act of 2025

This bill requires manufacturers to include a unique physical or chemical identifier on each pill of certain controlled substances in solid oral dosage form (like tablets or capsules). It directly affects pharmaceutical companies producing these specific medications, mandating the identifier to be added to every dose manufactured five years after the bill's enactment. The identifier must be machine-readable and help verify the product's authenticity throughout the supply chain. This change aims to improve tracking and combat counterfeit drugs in the distribution system.
