ATC follows guidelines [7] in creating new codes for newly approved drugs. In order to create a new ATC code, an application has to be sent to ATC. New ATC codes are published twice annually.[8] A formal release of new ATC edition occurs once a year.
Updates to ATC
National issues of the ATC classification, such as the German Anatomisch-therapeutisch-chemische Klassifikation mit Tagesdosen, may include additional codes and DDDs not present in the WHO version.[6]
National adaptations
Purpose
The ATC system also includes defined daily doses (DDDs) for many drugs. This is a measurement of drug consumption based on the usual daily dose for a given drug. According to the definition, "[t]he DDD is the assumed average maintenance dose per day for a drug used for its main indication in adults."[5]
Defined daily dose
Some codes are used exclusively for veterinary drugs, such as QI Immunologicals, QJ51 Antibacterials for intramammary use or QN05AX90 amperozide.[4]
The Anatomical Therapeutic Chemical Classification System for veterinary medicinal products (ATCvet) is used to classify veterinary drugs. ATCvet codes can be created by placing the letter Q in front of the ATC code of most human medications. For example, furosemide for veterinary use has the code QC03CA01.
ATCvet
Example: C03CA01 Furosemide
The fifth level of the code indicates the chemical substance and consists of two digits.
Fifth level
Example: C03CA Sulfonamides
The fourth level of the code indicates the chemical/therapeutic/pharmacological subgroup and consists of one letter.
Fourth level
Example: C03C High-ceiling diuretics
The third level of the code indicates the therapeutic/pharmacological subgroup and consists of one letter.
Third level
Example: C03 Diuretics
The second level of the code indicates the therapeutic main group and consists of two digits.
Second level
Example: C Cardiovascular system
The first level of the code indicates the anatomical main group and consists of one letter. There are 14 main groups:[3]
First level
In this system, drugs are classified into groups at 5 different levels:[2]

This therapeutic and chemical characteristics. Each bottom-level ATC code stands for a pharmaceutically used substance, or a combination of substances, in a single indication (or use). This means that one drug can have more than one code: acetylsalicylic acid (aspirin), for example, has A01 as a drug for local oral treatment, B01 as a platelet inhibitor, and N02 as an analgesic and antipyretic. On the other hand, several different brands share the same code if they have the same active substance and indications.
