NDC

A National Drug Code (NDC) is a unique 10- or 11-digit, 3-segment numeric identifier assigned to each medication listed under Section 510 of the US Federal Food, Drug, and Cosmetic Act.

RxCUI

An RxCUI is a machine-readable code or identifier that points to the common meaning shared by the various source names grouped and assigned to a particular concept.

RxNorm provides normalized names for clinical drugs and links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, Multum, and Gold Standard Drug Database. By providing links between these vocabularies, RxNorm can mediate messages between systems not using the same software and vocabulary.

ATC

ATC classifies drugs at five different levels. Each level is a different grouping of drugs. Groupings of active substances include the organ or system on which the drug acts as well as therapeutic, pharmacological, and chemical properties of the drug.

The Anatomical Therapeutic Chemical (ATC) classification was developed as a modification and extension of the EphMRA classification system. In the ATC classification system, the active substances are classified in a hierarchy with five different levels.

The system has fourteen main anatomical/pharmacological groups or 1st Levels.

Each ATC main group is divided into 2nd Levels which could be either pharmacological or therapeutic groups.

The 3rd and 4th Levels are chemical, pharmacological or therapeutic subgroups and the 5th Level is the chemical substance.

The 2nd, 3rd and 4th levels are often used to identify pharmacological subgroups when that is considered more appropriate than therapeutic or chemical subgroups.
