Modern Authentication of Pharmaceuticals Act of 2023

This bill requires pharmaceutical manufacturers to include a unique physical or chemical marker on controlled substances sold in solid oral dosage form (like pills) starting five years after enactment. The marker must be machine-readable and help verify product authenticity throughout the supply chain to combat counterfeits. It directly affects manufacturers of prescription opioids, stimulants, and other controlled substances in pill form. The law updates existing drug authentication requirements under the Federal Food, Drug, and Cosmetic Act to include this new verification method.
