A09AA Enzyme preparations
Only enzymes used in digestion disorders are classified in this group.
Other enzymes, see B06AA - Enzymes, and D03BA - Proteolytic
enzymes.
Enzyme preparations, which are indicated to treat inflammatory
conditions, are classified in M09AB - Enzymes.
Combinations of digestive enzymes and other agents (e.g. silicone
compounds and spasmolytics) are classified in this group if the main
indication is digestion disorders.
Cholagogues are classified in A05 - Bile and liver therapy.
DDDs can be difficult to establish because of great variations in
enzyme content. The DDDs are based on average recommended
doses given in different drug catalogues. Most of the preparations
are combinations of different enzymes, and the DDDs are therefore
given in UDs. Some specific products have been given a DDD, see
list of DDDs for combination products, www.whocc.no.
