ATC code H05
therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System: Calcium homeostasis
ATC code H05 Calcium homeostasis 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 H05 is part of the anatomical group H Systemic hormonal preparations, excluding sex hormones and insulins.
Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QH05. National versions of the ATC classification may include additional codes not present in this list, which follows the WHO version.
The public source identifies “ATC code H05” as therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System: Calcium homeostasis. This brief keeps that definition visible, then builds a research path around code, therapeutic and subgroup.
Why this record matters
A short description can identify a subject without explaining its stakes. For “ATC code H05”, the useful work is to connect “therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System: Calcium homeostasis” to the records capable of establishing context and consequence.
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 Q155761. 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.
