ATC R06 — antihistamínicos sistémicos. Algunos también aparecen en antigripales combinados; ver Medicamentos para resfriado y tos.
ATC R06——全身用抗组胺药。部分也出现在复方感冒药中；可与「感冒咳嗽药」对照。
ATC R06——全身用抗組胺藥。部分也出現在複方感冒藥中；可與「感冒咳嗽藥」對照。
Cross-over: R06 antihistamines may be components of combination cold medicines. All R06 are listed here; Cold & cough medicines only covers R05 + N02BE, so the two categories overlap.
Solapamiento: los antihistamínicos R06 pueden formar parte de antigripales combinados. Todo R06 está aquí; Medicamentos para resfriado y tos solo cubre R05 + N02BE, por lo que las categorías se solapan.
有交叉：R06 抗组胺药可能是复方感冒药的成分。全部 R06 列在本大类；「感冒咳嗽药」只含 R05 + N02BE，因此两个大类有重叠。
有交叉：R06 抗組胺藥可能是複方感冒藥的成分。全部 R06 列在本大類；「感冒咳嗽藥」只含 R05 + N02BE，因此兩個大類有重疊。

The market codes after a status are the markets where that status is recorded (same codes as the product tables). An ingredient can be on sale in one market and withdrawn in another; that is a record fact, not a safety judgement.

Class names are editorial translations or come from Wikipedia (CC BY-SA 4.0) / Wikidata (CC0); each ATC page lists the exact source, licence and link for every language. Only the ATC code and the WHO hierarchy are authoritative.
Notes & licences
Status badges summarise the product records held for each ingredient (active / discontinued / withdrawn / unknown), and the market codes after each badge show where that status is recorded. Only some registers publish a status column: CA, ES and MX do; AU and HK have no status column and are recorded as unknown; CN, US, GB, TW and SG records are on the register and marked active.
Class and category names are editorial or AI-assisted translations; only the ATC code and the WHO hierarchy are authoritative.
ATC codes and hierarchy reference the WHO Collaborating Centre for Drug Statistics Methodology ATC/DDD Index (copyright WHOCC; the index itself is not reproduced). Ingredient/strength facts come from the regulator records listed on About.
