US Drug Directory (FDA NDC) - every marketed drug product, cleaned
Every drug product marketed in the US in one clean reference table - the FDA National Drug Code directory, flattened. From openFDA's bulk NDC download (~137k products): one fat row per NDC with brand and generic names, active ingredients & strengths, dosage form, route, manufacturer/labeler, pharmacologic class, product type (prescription / OTC) and marketing category. The drug reference table health-tech, pharmacies, formularies and claims pipelines join on. Public domain / CC0.
