`rxnorm_ndc`

Pack: rxnorm · Endpoint: https://gateway.pipeworx.io/rxnorm/mcp

Get the NDC (National Drug Code) identifiers for a drug — the 11-digit US pharmacy codes used for billing, dispensing and inventory. Takes an RxCUI or a plain drug name (“amoxicillin”, “Lipitor”). NDCs attach to marketed products rather than to an ingredient, so an ingredient or brand name is expanded to its products automatically and the response says it did so; a concept with nothing currently marketed reports its historical NDC count instead of an unexplained empty list.

Parameters

Name	Type	Required	Description
`rxcui`	string	yes	RxNorm concept ID, or a drug name — resolved to an RxCUI automatically. A bare ingredient (“amoxicillin”) works: it is expanded to its marketed products. A full dose phrase (“lisinopril 10 mg oral tablet”) returns that one product’s complete list.
