ATC code A02

ATC code A02 Drugs for acid related 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.^[1]^[2]^[3] Subgroup A02 is part of the anatomical group A Alimentary tract and metabolism.^[4]

Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QA02.^[5]
National versions of the ATC classification may include additional codes not present in this list, which follows the WHO version.
