Muscoril Cps. (Thiocolchicoside)

Thiocolchicoside, the active ingredient in Muscoril Cps., is a muscle relaxant presented as an oral dosage form for oral use. It is used to relieve muscle spasm and associated musculoskeletal pain in adults.

GNH USA supplies Muscoril Cps. as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

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

- Muscle spasm: reduces the intensity and frequency of involuntary muscle contractions. - Musculoskeletal pain: alleviates pain associated with muscle strain or injury. - Acute low back pain: helps improve mobility and reduce discomfort.

Common side effects are generally mild and reversible.

Common Side Effects: - Drowsiness: feeling of sleepiness or reduced alertness. - Nausea: sensation of queasiness often leading to vomiting. - Dry mouth: reduced salivary flow causing oral discomfort. - Dizziness: sensation of light‑headedness or imbalance.

Serious or Rare Side Effects: - Allergic reactions: rash, angioedema, or anaphylaxis in susceptible individuals. - Hepatotoxicity: abnormal liver function tests or jaundice. - Seizures: rare occurrence of convulsive episodes, especially at high doses.

Before prescribing Thiocolchicoside, clinicians should consider several safety aspects.

- Assess hepatic and renal function: adjust use if significant impairment is present. - Contraindication: avoid in patients with known hypersensitivity to thiocolchicoside. - Elderly patients: monitor closely due to increased sensitivity to sedative effects. - Concomitant CNS depressants: avoid or use with caution as additive sedation may occur. - Store at ambient temperature: keep below 25°C, retain in original packaging, and protect from moisture.

Thiocolchicoside may interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - CNS depressants (e.g., benzodiazepines, opioids): may enhance sedation and respiratory depression. - Alcohol: can increase central nervous system depression. - Other muscle relaxants: additive muscle‑relaxant effect may lead to excessive weakness.

Moderate Interactions (Monitor Closely): - CYP3A4 inhibitors (e.g., ketoconazole): may raise thiocolchicoside plasma levels. - CYP3A4 inducers (e.g., rifampicin): may reduce therapeutic effectiveness. - Antihistamines: may increase drowsiness when combined.
