Notes

(1)

Attention is drawn to the Notes in class C07, for example the Notes following the title of subclass C07D, setting forth the rules for classifying organic compounds in that class, which rules are also applicable, if not otherwise indicated, to the classification of organic compounds in group A61K 31/00. [7]

(2)

Salts or complexes of organic active compounds are classified according to the base active compounds. If a complex is formed between two or more active compounds, classification is made in the last appropriate place. [7]

(3)

Organic active compounds forming salts or complexes with heavy metals are not classified in groups A61K 31/28, A61K 31/555 or A61K 31/7135, unless explicit indication to the contrary is made, e.g. hemin A61K 31/555, cyanocobalamin A61K 31/714. [7]
