Introduced: July 1974

Title

Titles differ between systems:

IPC: Amines, e.g. amantadine

CPC: Amines

Full titles differ between systems:

IPC:

Medicinal preparations containing organic active ingredients > Amines, e.g. amantadine

CPC:

Medicinal preparations containing organic active ingredients > Amines

IPC and CPC are identically structured here. All 8 subcodes exist in both systems.

5 shared codes have differing titles between IPC and CPC.
