rxnorm_search — Look up a medication's RxCUI and MAP A BRAND DRUG TO ITS GENERIC INGREDIENT (and vice versa) — e.g. Eliquis -> apixaban, Lipitor -> atorvastatin. Search by brand or generic name; returns RxCUI IDs, names, synonyms, and term types (BN=brand, IN=ingredient, SBD=dose form). The right tool for "what is the RxCUI for X", "what generic ingredient does brand X map to", or "brand vs generic name". Start here to find a drug's unique ID.
rxnorm_get_properties — Get full medication details by RxCUI ID. Returns name, synonyms, term type, language, and status. Use after rxnorm_search to retrieve complete drug information.
rxnorm_related — Find related medications by RxCUI — brands, generics, ingredients, and dose forms. Maps between brand and generic alternatives. Use to compare drug options.
rxnorm_ndc — 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.
