Opioids are used increasingly in the management of moderate-to-severe chronic non-cancer pain (CNCP). Opioid-induced bowel disorders (OBD) markedly impact health-related quality life (HRQoL) and frequently limit medically indicated opioid pharmacotherapy. We assessed risk factors, effect OBD on HRQoL CNCP patients. also estimated likely prevalence narcotic syndrome (NBS). These effects have been reported cancer patients but not previously.Ambulatory (n = 146) taking regularly scheduled...
