NOTE
-
Among the one-dot groups of A61K 9/00 , classification is not made in the last
appropriate place.
A61K 9/00 is subdivided according to the following concepts:
- the drug release technique ( A61K 9/0002 and subgroups),
- the site of application ( A61K 9/0012 and subgroups), and
- the physical form ( A61K 9/0087 to A61K 9/70 E).
Where relevant, documents are classified in more than one of these subdivisions.
