The dilemma of opioid-induced hyperalgesia and tolerance in chronic opioid therapy.
Opioids have been used for decades and continue to be used to treat severe, acute, chronic non-cancer and cancer pain.1,2 They work mainly by inhibiting spinal cord neuronal transduction and the ascending pain signals at midbrain nuclei, and through the modulation of limbic system pain perception.3 The main opioids receptors are mu and kappa receptors.1–3 The use of opioids can be challenging a...
متن کاملMechanisms of opioid-induced tolerance and hyperalgesia.
Opioid tolerance and opioid-induced hyperalgesia are conditions that negatively affect pain management. Tolerance is defined as a state of adaptation in which exposure to a drug induces changes that result in a decrease of the drug's effects over time. Opioid-induced hyperalgesia occurs when prolonged administration of opioids results in a paradoxic increase in atypical pain that appears to be ...
متن کاملOpioid tolerance and hyperalgesia.
Opioids have been successfully used for the management of acute and cancer-related pain. Concerns regarding side effects, tolerance, dependence, addiction, and hyperalgesia have limited the use of opioids for the management of chronic nonmalignant pain. This article will review updated information from both clinical and preclinical studies regarding opioid-induced hyperalgesia, tolerance, and d...
متن کاملDifferential Opioid Tolerance and Opioid-induced Hyperalgesia: A Clinical Reality.
Anesthesiology, V 124 • No 2 483 February 2016 O PIOIDS are highly effective analgesics and as such form the mainstay of pain management after surgery. However, they are associated with a formidable array of side effects, some of them potentially lethal. Also, the opioid signaling system has a remarkable ability—possibly unequaled by any other receptor system...
متن کاملChronic Opioid Therapy and Opioid Tolerance: A New Hypothesis
Opioids are efficacious and cost-effective analgesics, but tolerance limits their effectiveness. This paper does not present any new clinical or experimental data but demonstrates that there exist ascending sensory pathways that contain few opioid receptors. These pathways are located by brain PET scans and spinal cord autoradiography. These nonopioid ascending pathways include portions of the ...
