RxNorm Drug Search by Name (RxCUIs for Brand and Generic Products)

rxnorm/drug-search

Finds the products RxNorm holds for a drug name, brand or generic, with their RxCUI codes. Returns NLM's drugGroup response unchanged: concepts grouped by term type, SCD (generic clinical drug: ingredient, strength, dose form), SBD (branded drug), GPCK and BPCK (generic and branded packs), each with rxcui, the RxNorm normalized name and a display synonym. It lists products only: the ingredient and brand-name concepts themselves are not returned (use related concepts for those). An ingredient name or an ingredient plus strength matches; a brand plus a strength does not. A name RxNorm does not hold returns an empty answer, not an error. Source: RxNorm, from the U.S. National Library of Medicine's RxNav API; Omnial is not an NLM product and NLM is not responsible for it.
