Ages Eligible for Study:
18 Years and older (Adult, Senior)
Sexes Eligible for Study:
Male and female outpatients 18 years of age or older.
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.
Chronic pain which has been present for a minimum of 3 months which needs the chronic use of opioids for pain relief.
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:
hard or very hard stools
sensation of incomplete evacuation
straining while having a bowel movement
Patients who are receiving opioids for abdominal pain or connective tissue disorders.
Planned discontinuation or an increase or decrease by more than 30% of the current opioid dose
Patients who underwent major surgery within 3 months prior to screening.
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.
Patients with a current diagnosis of irritable bowel syndrome (IBS) constipation predominant or alternators.
