The Anatomical Therapeutic Chemical (ATC) Classification System is a drug classification system that classifies the active ingredients of drugs according to the organ or system on which they act and their therapeutic , pharmacological and chemical properties. Its purpose is an aid to monitor drug use and for research to improve quality medication use. It does not imply drug recommendation or efficacy . It is controlled by the World Health Organization Collaborating Centre for Drug Statistics Methodology (WHOCC), and was first published in 1976.

100-432: A final decision and published semi-annually on the website and WHO Drug Information and implemented in the annual print/on-line ACT/DDD Index on January 1. Changes to existing ATC/DDD follow a similar process to become temporary codes and if accepted become a final decision as ATC/DDD alterations. ATC and DDD alterations are only valid and implemented in the coming annual updates; the original codes must continue until

160-580: 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." 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
180-417: Is a strict hierarchy, meaning that each code necessarily has one and only one parent code, except for the 14 codes at the topmost level which have no parents. The codes are semantic identifiers, meaning they depict information by themselves beyond serving as identifiers (namely, the codes depict themselves the complete lineage of parenthood). As of 7 May 2020, there are 6,331 codes in ATC; the table below gives
200-614: Is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System , a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. Subgroup B05 is part of the anatomical group B Blood and blood forming organs . Codes for veterinary use ( ATCvet codes ) can be created by placing the letter Q in front of
220-557: Is an ATC classification of herbal substances ; it differs from the regular ATC system by using 4 digits instead of 2 at the 5th level group. The herbal classification is not adopted by WHO. The Uppsala Monitoring Centre is responsible for the Herbal ATC classification, and it is part of the WHODrug Global portfolio available by subscription . The ATC system also includes defined daily doses (DDDs) for many drugs. This

#1732771986606240-526: Is an extension and modification of the EphMRA's. It was first published in 1976. In this system, drugs are classified into groups at five different levels: The first level of the code indicates the anatomical main group and consists of one letter. There are 14 main groups: Example : C Cardiovascular system The second level of the code indicates the therapeutic subgroup and consists of two digits. Example : C 03 Diuretics The third level of
260-403: 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 Q C03CA01. Some codes are used exclusively for veterinary drugs, such as QI Immunologicals , QJ51 Antibacterials for intramammary use or QN05AX90 amperozide . The Herbal ATC system (HATC)

300-520: The WHO version. ATC follows guidelines in creating new codes for newly approved drugs. An application is submitted to WHO for ATC classification and DDD assignment. A preliminary or temporary code is assigned and published on the website and in the WHO Drug Information for comment or objection. New ATC/DDD codes are discussed at the semi-annual Working Group meeting. If accepted it becomes
320-517: The code indicates the therapeutic/pharmacological subgroup and consists of one letter. Example : C03 C High-ceiling diuretics The fourth level of the code indicates the chemical/therapeutic/pharmacological subgroup and consists of one letter. Example : C03C A Sulfonamides The fifth level of the code indicates the chemical substance and consists of two digits. Example : C03CA 01 furosemide The Anatomical Therapeutic Chemical Classification System for veterinary medicinal products (ATCvet)
340-614: The count per level. The ATC system is based on the earlier Anatomical Classification System, which is intended as a tool for the pharmaceutical industry to classify pharmaceutical products (as opposed to their active ingredients). This system, confusingly also called ATC, was initiated in 1971 by the European Pharmaceutical Market Research Association (EphMRA) and is being maintained by the EphMRA and Intellus. Its codes are organised into four levels. The WHO's system, having five levels,
360-430: The human ATC code: for example, QB05 . ATCvet codes without corresponding human ATC codes are cited with the leading Q in the following list. National issues of the ATC classification may include additional codes not present in this list, which follows the WHO version.

400-481: The organ or system on which they act, their therapeutic intent or nature, and the drug's chemical characteristics . Different brands share the same code if they have the same active substance and indications. 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, for example acetylsalicylic acid (aspirin) has A01AD05 ( WHO ) as
