Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All

Inclusion Criteria:

  1. Male and female outpatients 18 years of age or older.
  2. Patients with chronic non-cancer pain that necessitates the use of non-injectable opioid analgesics. The equivalent dose of 300 mg morphine per day is the maximum opioid analgesic dose allowed. In general, patients should be using opioids on a daily basis.
  3. Chronic pain which has been present for a minimum of 3 months which needs the chronic use of opioids for pain relief.
  4. Constipation, according to the investigator's clinical judgment, that is resulting from opioid use for non-cancer chronic pain. Opioid-induced constipation (OIC) is defined as follows:

    • less than 3 spontaneous bowel movements per week and at least one of the following on at least 25% of occasions:

      1. hard or very hard stools
      2. sensation of incomplete evacuation
      3. straining while having a bowel movement

Exclusion Criteria:

  1. Patients who are receiving opioids for abdominal pain or connective tissue disorders.
  2. Planned discontinuation or an increase or decrease by more than 30% of the current opioid dose
  3. Patients who underwent major surgery within 3 months prior to screening.
  4. Patients with a history of prior chronic constipation (CC) that was present for more than three months and that was not related to opioid use.
  5. Patients with a current diagnosis of irritable bowel syndrome (IBS) constipation predominant or alternators.

Other protocol-defined inclusion/exclusion criteria may apply.
