[Non-opioid analgesics in cancer pain].
Non-opioid analgesics such as NSAIDs play a central role for patients with cancer pain as well as for those with acute pain. Pain management using non-opioid analgesics need to avoid potential side effects, and the analgesic action of NSAIDs, cyclooxygenase inhibitors, would synergistically potentiate opioids' effects via the activation of the periaquaductal grey of the midbrain. The analgesic action of opioids would also be potentiated by the activation of alpha 2-adrenoceptors of the spinal cord. Thus the use of non-opioid analgesics for cancer patients taking opioid needs meticulous care. Undertreatment of pain is a persistent clinical problem for patients with cancer. Although changing medical practice is difficult and improving pain management with the rational use of combination of drugs may especially difficult, supplementation of non-opioid analgesics for opioid treatment would provide a better quality of life of cancer patients.
