Opioid Therapy for Chronic Noncancer Pain: Safe, Effective, Appropriate?
In determining the appropriate role of opioids, two public health crises must be balanced: the opioid abuse epidemic and the “silent” crisis of unrelieved chronic pain. Opioids can be used safely and effectively in selected patients; however, clinicians must be aware of their abuse liability and individual risk factors for opioid misuse. A number of opioids are approved for use in the United States, and although there are class effects, there can be great variability among patients with regard to opioid response. In addition to the medication, prescribers must also determine the most appropriate dose and route of administration. Considerations must be made for special population, such as the renally impaired, those with hepatic dysfunction, and pediatric and elderly patients. Another factor is abuse-deterrent properties. Of particular interest as an opioid agent is buprenorphine, which is available in various routes of administration and because of its unique pharmacokinetics may be administered to renally compromised and elderly patients without dosing restrictions. Buprenorphine is also associated with a lower abuse liability than other opioids. Patients suffering moderate to severe pain syndromes should not be denied access to effective pain control, which in some cases may appropriately include opioid therapy.
