ATC code L02 Endocrine therapy 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] Subgroup L02 is part of the anatomical group L Antineoplastic and immunomodulating agents.[3]

ATC codes
L Antineoplastic and immunomodulating agents
L01 Antineoplastic agents
L02 Endocrine therapy

Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QL02.[4]
