| It is rare to completely achieve absolute and sustained relief of pain. Thus, the clinical goal is pain management. Pain management is often multidisciplinary in nature. A recent journal article by Gatchell and Okifuji recognizes the importance of comprehensive pain programs(CPPs) in the management of chronic pain. They summarize their findings as follows: "CPPs offer the most efficacious and cost-effective treatment for persons with chronic pain, relative to a host of widely used conventional medical treatment." <ref name="Henningsen P, Zipfel S.">{{cite journal |author=Henningsen P, Zipfel S, Herzog W |title=Management of functional somatic syndromes |journal=Lancet |volume=369 |issue=9565 |pages=946-55 |year=2007 |pmid=17368156}}</ref><ref name="Stanos S, Houle TT.">{{cite journal |author=Stanos S, Houle TT |title=Multidisciplinary and interdisciplinary management of chronic pain |journal=Physical medicine and rehabilitation clinics of North America |volume=17 |issue=2 |pages=435-50, vii |year=2006 |pmid=16616276}}</ref>

| ===Opioids for Chronic Pain===
| |
| [[Opioid]] medications provide short, intermediate and long acting analgesia depending upon the specific properties of the medication and whether it is formulated as an extended release drug. Opioid medications may be administered orally, by injection, via nasal mucosa or oral mucosa, rectal, transdermal, intravenously, epidurally and intrathecally. In chronic pain conditions that are opioid responsive a combination of a long acting or extended release medication is often prescribed in conjunction with a shorter acting medication for break through pain (exacerbations).
| |
| Although opioids are strong analgesics, they do not provide complete analgesia regardless of whether the pain is acute or chronic in origin. Opioids are efficacious analgesics in chronic malignant pain and modestly effective nonmalignant pain management. However, there are variable associated adverse effects, especially during the commencement or change in dosing and administration. When [[opioids]] are used for prolonged periods [[drug tolerance]], [[chemical dependency]] and (rarely) [[addiction]] may occur. [[Chemical dependency]] is ubiquitous among [[opioid]] therapy after continuous administration; however, [[drug tolerance]] is not well studied in patients on long term opioid therapy. [[ Addiction]] rarely occurs as a result of opioid prescription, but they are abused by some individuals, which can cause concern to health care providers. Diversion of opioid medications is another concern for health care providers.

| ===Non-Steroidal Anti-Inflammatory Drugs===
| |
| The other major group of analgesics are [[Non-steroidal anti-inflammatory drug]]s ([[NSAID]]). This class of medications includes acetaminophen which may be administered as a single medication or in combination with other analgesics. The alternatively prescribed NSAIDs such as ketoprofen and piroxicam, have limited benefit in chronic pain disorders and with long term use is associated with significant adverse effects. The use of selective NSAIDs designated as selective COX-2 inhibitors have significant cardiovascular and cerebrovascular risks which have limited their utilization.<ref name="Munir MA, Enany N.">{{cite journal |author=Munir MA, Enany N, Zhang JM |title=Nonopioid analgesics |journal=Med.

| |
| | |
| ===Antidepressants and Antiepileptic Drugs===
| |
| Some [[antidepressant]] and [[antiepileptic]] drugs are used in chronic pain management and act primarily within the pain pathways of the central nervous system, though peripheral mechanisms have been attributed as well. These mechanisms vary and in general are more effective in [[neuropathy|neuropathic]] pain disorders as well as [[complex regional pain syndrome]].<ref name="Jackson KC 2nd.">{{cite journal |author=Jackson KC |title=Pharmacotherapy for neuropathic pain |journal=Pain practice : the official journal of World Institute of Pain |volume=6 |issue=1 |pages=27-33 |year=2006 |pmid=17309706}}</ref> Drugs such as [[Gabapentin]] have been widely prescribed for the off-label use of pain control.

| ===Interventional Therapy===
