HAYWARD, Calif., Dec. 22, 2016 /PRNewswire/ -- Impax Laboratories, Inc. (NASDAQ: IPXL), a specialty pharmaceutical company, today announced the launch of a generic version of Kadian (morphine sulfate) Extended Release Capsules, USP CII 20, 30, 50, 60, 80, 100 mg.

Addiction, Abuse, and Misuse

Morphine sulfate extended release capsules exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing KADIAN, and monitor all patients regularly for the development of these behaviors or conditions.


Life-threatening Respiratory Depression

Serious, life-threatening, or fatal respiratory depression may occur with use of morphine sulfate extended-release capsules. Monitor for respiratory depression, especially during initiation of morphine sulfate extended release capsules or following a dose increase. Instruct patients to swallow morphine sulfate extended release capsules whole; crushing, chewing, or dissolving morphine sulfate extended release capsules can cause rapid release and absorption of a potentially fatal dose of morphine.


Accidental Ingestion

Accidental ingestion of even one dose of morphine sulfate extended release capsules , especially by children, can result in a fatal overdose of morphine.


Neonatal Opioid Withdrawal Syndrome

Prolonged use of morphine sulfate extended release capsules during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.


Interaction with Alcohol

Instruct patients not to consume alcoholic beverages or us e prescription or non-prescription products that contain alcohol while taking morphine sulfate extended release capsules. The co-ingestion of alcohol with morphine sulfate extended release capsules may result in increased plasma levels and a potentially fatal overdose of morphine.


Morphine sulfate extended-release capsules, USP are an opioid agonist indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Limitations of Use

Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations, reserve morphine sulfate extended-release capsules, USP for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.  Morphine sulfate extended-release capsules, USP are not indicated as an as-needed (prn) analgesic.


  • Significant respiratory depression
  • Acute or severe bronchial asthma
  • Known or suspected paralytic ileus

  • Interaction with CNS depressants: Concomitant use may cause profound sedation, respiratory depression, and death. If co-administration is required, consider dose reduction of one or both drugs because of additive pharmacological effects.
  • Elderly, cachectic, debilitated patients and those with chronic pulmonary disease: Monitor closely because of increased risk for life-threatening respiratory depression.
  • Hypotensive effect: Monitor during dose initiation and titration
  • Patients with head injury or increased intracranial pressure: Monitor for sedation and respiratory depression and avoid use of morphine sulfate extended-release capsules in patients with impaired consciousness or coma susceptible to intracranial effects of CO2 retention.


Most common adverse reactions (>10%): constipation, nausea, and somnolence.


  • Mixed agonist/antagonist opioid analgesics: Avoid use with morphine sulfate extended-release capsules because they may reduce analgesic effect of morphine sulfate extended-release capsules or precipitate withdrawal symptoms.
