Mst Continus (Morphine Sulfate)

Morphine Sulfate, the active ingredient in Mst Continus, is an opioid analgesic presented as a oral formulation for oral use. It treats moderate to severe pain in adult patients requiring strong analgesia.

GNH USA supplies Mst Continus as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Morphine Sulfate is an opioid analgesic used to manage pain conditions that involve the central nervous system.

- Moderate to severe acute pain: provides rapid and effective relief after surgery or trauma. - Cancer‑related pain: helps control persistent pain associated with malignant disease. - Chronic severe pain: offers long‑term analgesia for conditions such as severe osteoarthritis when other treatments are insufficient.

Morphine Sulfate may cause a range of adverse reactions, from mild to life‑threatening.

Common Side Effects: - Nausea: feeling of sickness or urge to vomit. - Constipation: reduced bowel movements and hard stools. - Drowsiness: increased sleepiness or fatigue. - Dizziness: sensation of light‑headedness or unsteadiness. - Dry mouth: reduced salivation leading to throat discomfort. - Sweating: excessive perspiration unrelated to temperature.

Serious or Rare Side Effects: - Respiratory depression: slowed or shallow breathing that can be fatal. - Severe hypotension: marked drop in blood pressure causing faintness. - Anaphylaxis: rapid, severe allergic reaction with rash, swelling, and airway compromise. - Adrenal insufficiency: inadequate cortisol production leading to fatigue and weakness. - Seizures: uncontrolled electrical activity in the brain. - Dependence or addiction: compulsive use despite harmful consequences.

When prescribing or dispensing Morphine Sulfate, several safety considerations are essential.

- Assess pain severity: confirm that the pain level justifies opioid therapy. - Evaluate organ function: check renal and hepatic status before initiating treatment. - Monitor respiratory status: observe for signs of slowed breathing, especially after dose adjustments. - Avoid concurrent CNS depressants: limit use with benzodiazepines, barbiturates, or alcohol. - Use the lowest effective dose: titrate to achieve pain control while minimizing side effects. - Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Morphine Sulfate can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - CNS depressants (e.g., benzodiazepines, barbiturates): may cause profound respiratory depression. - Monoamine oxidase inhibitors (MAOIs): increase risk of serotonin syndrome. - Other opioids: additive effects on sedation and respiratory function. - Alcohol: enhances central nervous system depression. - Respiratory depressants (e.g., gabapentinoids): potentiate breathing suppression.

Moderate Interactions (Monitor Closely):\n- CYP3A4 inhibitors (e.g., erythromycin, ketoconazole): may raise morphine plasma levels. - CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce analgesic effect. - Antihistamines: can increase sedation. - Diuretics: may exacerbate hypotension. - Certain antidepressants (e.g., SSRIs): may increase risk of serotonin syndrome.
