ATC code R06

ATC code R06 Antihistamines for systemic use 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 R06 is part of the anatomical group R Respiratory system.[3]

ATC codes
R Respiratory system
R01 Nasal preparations
R02 Throat preparations
R03 Drugs for obstructive airway diseases
R05 Cough and cold preparations
R06 Antihistamines for systemic use
R07 Other respiratory system products

Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QR06.[4]

National issues of the ATC classification may include additional codes not present in this list, which follows the WHO version.
