What is RxNorm?

RxNorm is a system developed and maintained by the National Library of Medicine (NLM). RxNorm is a normalized naming system for generic and branded drugs. RxNorm is also a tool that supports interoperability between different drug terminologies and other naming systems.

The goal of RxNorm is to facilitate the efficient exchange of drug information among the computer systems used by hospitals, pharmacies, clinics and other organizations. To achieve this goal RxNorm provides normalized names and unique identifiers for drugs and medicines.

What is an RXCUI?

An RxCUI is machine readable unique identifier that defines the same common concept. Every name and code provided to the National Library of Medicine receives an RXCUI. Drug products that map to the same RxCUI are considered the same drug while drugs that are distinct will have different RxCUIs.

What is a Term Type (TTY)?

Term Types (TTYs) are used to specify the level of complexity of each RxCUI term.
