Changelog · versioned releases and corrections

US drug-product identity release at one openFDA product_ndc per row; package NDCs are aliases and optional enrichments retain source provenance. Shortages and UNIIs remain source-owned sidecars. FDA PMR/PMC, FDA IID, CMS SDUD, Drugs@FDA lifecycle, and FDA REMS records are delivered as separately grained auxiliary tables and never widen product identity. Suppressed CMS measures remain null; CMS reimbursement is not price or coverage. Product-NDC applicability is not asserted for the regulatory auxiliary roots, and IID excludes CAS Registry Numbers. RxNorm fields are limited to the reviewed RXNORM/MTHSPL subset; FDA, NLM, and CMS data carries a non-endorsement disclaimer. Product changes since the previous release: openFDA drug shortage availability values are normalized to canonical statuses for records with verbose logistics prose, and provenance documentation publishes tiered evidence-link liveness claims.

• — Records +134; provenance +1,960.

Schema and field surface

• id: RxAtlas canonical drug-product id.
• primary_source: Source code for the first source that created the canonical record.
• source_id: First-seen source identifier used to seed the canonical record, such as an NDC, RxCUI, SPL set id, or application number.
• source_record_url: URL for the latest source record that contributed to the canonical row.
• ndc_list: Distinct NDCs observed across source records for this canonical product.

Source coverage

• CMS SDUD: State and national aggregate Medicaid utilization facts at utilization-type, exact NDC11, year, and quarter grain; suppressed measures remain null and reimbursement is not represented as price or coverage.
• DailyMed: Structured Product Label titles, versions, and publication dates joined to the SPL set identifiers carried by FDA product records.
• Drugs@FDA: FDA application, product-number, submission, and document-metadata records delivered as separate auxiliary tables without claiming product-number-to-NDC applicability.

Buyer caveats

• RxAtlas is reference data, not medical advice, prescribing advice or reimbursement advice.
• Buyers remain responsible for validating source terms and regulated use in their own workflow.
