ATC code C04
therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System: Peripheral vasodilators
ATC code C04 Peripheral vasodilators 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. Subgroup C04 is part of the anatomical group C Cardiovascular system.
Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QC04. ATCvet codes without corresponding human ATC codes are cited with the leading Q in the following list.National versions of the ATC classification may include additional codes not present in this list, which follows the WHO version.
“ATC code C04” enters the record as therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System: Peripheral vasodilators. Crown Archives preserves that source wording while asking what code, therapeutic and subgroup can confirm, complicate or overturn.
Why this record matters
“ATC code C04” is worth following because a concise public description often conceals a longer documentary argument. Here, code, therapeutic and subgroup provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 28, 2026. The linked authority identifier is Q433887. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
