What is the medicine Miosan for?

According to the instructions on the package insert, the drug Miosan can be prescribed for the treatment of muscle spasms (involuntary contractions of the muscles), especially when associated with acute and painful musculoskeletal conditions, such as:

  • Backache;
  • Torticollis;
  • Scapulameral periarthritis (disorder that affects the shoulder);
  • Cervicobraquialgias (pain that radiates from the neck to the arms);
  • Fibromyalgia.

The package insert also reinforces that the medication can be prescribed to act as a complement to other common treatments (such as physiotherapy) in cases of conditions such as those mentioned.

Is it muscle relaxant?

-Yeah . The Miosan remedy is regulated by Anvisa (National Health Surveillance Agency) under registration nº101180129 and falls within the therapeutic class of muscle relaxants.

Therefore, it can be used to relieve pain and tension in the body’s muscles.

What is the active principle of Miosan?

The active ingredient in Miosan is Cyclobenzaprine Hydrochloride , a drug substance that acts as a muscle relaxant in the body.

This compound suppresses skeletal muscle spasm of local origin, but without interfering with the muscular function of the affected area (it does not cause changes in muscle function). Thus, it provides relief from acute pain or discomfort (such as low back pain and torticollis, for example).

However, the label for this active substance reinforces that Cyclobenzaprine Hydrochloride is ineffective in muscle spasms due to diseases of the central nervous system .
