Miorexil (Thiocolchicoside)

Thiocolchicoside, the active ingredient in Miorexil, is a skeletal muscle relaxant presented as an injectable solution for intramuscular use. It acts on the central nervous system to alleviate muscle spasm, musculoskeletal pain, and acute low back pain, primarily in adult patients requiring short‑term relief.

GNH USA supplies Miorexil as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU quality standards and provides regulatory documentation for global distribution.

Thiocolchicoside is indicated for conditions involving skeletal muscle spasm and related pain.

- Muscle spasm: reduces involuntary muscle contraction and associated discomfort. - Musculoskeletal pain: alleviates pain linked to muscle strain or injury. - Acute low back pain: provides short‑term relief of pain and functional limitation.

Common Side Effects: - Dizziness: sensation of light‑headedness or unsteadiness. - Drowsiness: increased sleepiness or reduced alertness. - Nausea: feeling of queasiness or urge to vomit. - Headache: mild to moderate cranial pain. - Injection site pain: discomfort at the intramuscular injection site. - Hypotension: transient lowering of blood pressure.

Serious or Rare Side Effects: - Allergic reactions: rash, itching, swelling, or anaphylaxis. - Stevens‑Johnson syndrome: severe skin blistering and mucosal involvement. - Liver enzyme elevation: abnormal hepatic function tests. - Seizures: rare occurrence of convulsive episodes. - Severe hypotension: marked drop in blood pressure requiring medical attention.

Precautions should be observed when prescribing Thiocolchicoside.

- Assess renal and hepatic function: adjust use if impairment is present. - Use with caution in the elderly: increased susceptibility to sedation and falls. - Avoid in patients with known hypersensitivity: discontinue if allergic signs appear. - Monitor for sedation: avoid operating machinery or driving if drowsy. - Avoid concomitant CNS depressants: may enhance sedation and respiratory depression. - Store at ambient temperature: keep in the original pack, protect from moisture and light.

Thiocolchicoside may interact with other medications.

Major Interactions (Avoid): - Other central muscle relaxants (e.g., baclofen, tizanidine): increased risk of profound CNS depression. - Monoamine oxidase inhibitors (MAOIs): potential for severe hypotension.

Moderate Interactions (Monitor Closely): - Benzodiazepines or opioids: may enhance sedation and respiratory effects. - Antihistamines: could increase drowsiness. - Alcohol: may potentiate central nervous system depression.
