ATC code 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 Other ATC codes A B C D G H QI J L M N P R S V

**ATC code R** *Respiratory system* is a section of the [Anatomical Therapeutic Chemical Classification System](/source/Anatomical_Therapeutic_Chemical_Classification_System), a system of alphanumeric codes developed by the [World Health Organization](/source/World_Health_Organization) (WHO) for the classification of [drugs](/source/Pharmaceutical_drug) and other medical products.[1][2][3][4]

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