Thiocolchicoside is a muscle relaxant with anti-inflammatory and analgesic effects. It acts as a competitive GABA-A receptor antagonist and also glycine receptor antagonist with similar potency and nicotinic acetylcholine receptors to a much lesser extent.

Thiocolchicoside is used as a muscle relaxant in the treatment of painful muscular conditions. It is thought to act on receptors in the nervous system that are involved in the regulation of muscle function.

Intramuscular administration is contraindicated in patients receiving anti-coagulant therapy and in patients with bleeding.

Thiocolchicoside should not be used in patients with severe renal failure.

  • Abdominal cramps
  • Abdominal bloating
  • Abdominal pain
  • Diarrhea
  • Dizziness
