RxNorm API — oanor API marketplace

RxNorm API

US drug terminology as an API, powered by the U.S. National Library of Medicine's RxNav / RxNorm service. Resolve any drug or medication name to its RxNorm concept identifier (RxCUI); read a concept's properties (preferred name, term type, synonym, UMLS id); find all the related drug products for a name grouped by term type (brand names, ingredients, clinical and branded drugs, dose forms); walk related concepts by term type; list the drug classes a medicine belongs to across ATC, VA, mechanism of action, physiologic effect and chemical structure; and run spelling-tolerant search that returns candidate RxCUIs with match scores for misspelled or partial names. The standardised vocabulary that underpins US electronic health records and e-prescribing. Ideal for EHR and pharmacy systems, medication reconciliation, clinical-decision-support and health apps, and drug-data normalisation pipelines. RxCUIs are numeric.
