Responsible Prescribing of Opioids for the Management of Chronic Pain

The management of patients with chronic pain is a common clinical challenge. Indeed, chronic pain is often inadequately controlled in patients with cancer and in those with non-cancer chronic pain. Because of the complex nature of chronic pain, successful long-term treatment is more difficult than for acute pain. Most often acute pain is nociceptive, whereas chronic pain can be nociceptive (i.e., in response to noxious stimuli), neuropathic (i.e., initiated by a primary lesion or dysfunction in the nervous system) or mixed in origin.
