United States Drug Product Directory
Catalogue of prescription and over-the-counter drug products sold in the United States.
The national directory of finished and unfinished drug products, listing each product's identifying code, brand and generic names, dosage form, labeller and marketing category. It is reference data about products, not about patients or prescriptions. Health-tech products, pharmacy tools and clinical AI agents use it to resolve a drug name to a canonical product record.
