M03 MUSCLE RELAXANTS

This group comprises peripherally, centrally and directly acting muscle relaxants.

See also G04BD - Drugs for urinary frequency and incontinence.


M03A MUSCLE RELAXANTS, PERIPHERALLY ACTING AGENTS

This group comprises peripherally acting muscle relaxants such as curare alkaloids and suxamethonium.

The drugs in this group are mainly used together with anesthetics.

As for other drugs used in general anesthesia (see N01A), no DDDs have been established in this group because the doses used vary substantially.

This group comprises centrally acting muscle relaxants. Combined preparations are classified at separate 5th levels using the corresponding 50-series (comb. Excl. psycholeptics), or the 70-series (comb. With psycholeptics):
The group is subdivided according to chemical structure.

Combinations with NSAIDs (M01A) or analgesics (N02B) are classified here.

These drugs are used in different conditions associated with pain and rigidity in the muscles, joints etc.

DDDs for combination products, see list on the website www.whocc.no.
