Pharmaceutical drug classification
ATC code G Genito-urinary system and sex hormones is a section 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] [ 4]
Codes for veterinary use (ATCvet codes ) can be created by placing the letter Q in front of the human ATC code: for example, QG .[ 5]
