Full Title

Full titles differ between systems:

IPC:

Medicinal preparations containing organic active ingredients > Carbohydrates; Sugars; Derivatives thereof > Compounds having three or more nucleosides or nucleotides

CPC:

Medicinal preparations containing organic active ingredients > Carbohydrates; Sugars; Derivatives thereof (sorbitol A61K31/047) > Compounds having three or more nucleosides or nucleotides

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

IPC defines codes here since 2000.
