# ATC code A03

ATC code A03 Drugs for functional gastrointestinal disorders 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 A03 is part of the anatomical group A Alimentary tract and metabolism.
Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QA03. 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.
