QA03
DRUGS FOR FUNCTIONAL GASTROINTESTINAL DISORDERS
Preparations containing, for example, analgesics and antispasmodics could be
classified either in this group or in QN02 - Analgesics. Combinations of
psycholeptics and antispasmodics could be classified in QN05 - Psycholeptics etc.
The main indication for the use of the drug, together with the relative effect of the
active components, will decide the classification. In the treatment of pain caused by
spasms, the spasmolytic component must be judged more important than the
analgesic component. Accordingly, an analgesic/antispasmodic combination should
be classified in QA03 if the main effect of the agent is its antispasmodic action.
Combined preparations are classified in:
QA03D - Antispasmodics in combination with analgesics
QA03E - Antispasmodics and anticholinergics in combination with other drugs
Antispasmodics which are used specifically in the urogenital tract are classified in
QG04BD - Urinary antispasmodics.
Lubiprostone is classified in QA06AX - Other laxatives.
Peripheral opioid receptor antagonists are classified in QA06AH.
