ATC code M: Musculo-skeletal system
Other ATC codes

ATC code M03 Muscle relaxants 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 M03 is part of the anatomical group M Musculo-skeletal system.[4]

Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QM03.[5] 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.
