Opioids and central sensitisation: II. Induction and reversal of hyperalgesia.
نویسندگان
چکیده
Opioids are powerful analgesics when used to treat acute pain and some forms of chronic pain. In addition, opioids can preempt some forms of central sensitization. Here we review evidence that opioids may also induce and perhaps reverse some forms of central sensitization.

Hyperalgesia by synaptic long-term potentiation (LTP): an update
Long-term potentiation of synaptic strength (LTP) in nociceptive pathways shares principle features with hyperalgesia including induction protocols, pharmacological profile, neuronal and glial cell types involved and means for prevention. LTP at synapses of nociceptive nerve fibres constitutes a contemporary cellular model for pain amplification following trauma, inflammation, nerve injury or w...
متن کاملPain after total knee arthroplasty: a narrative review focusing on the stratification of patients at risk for persistent pain.
The patient with a painful arthritic knee awaiting total knee arthroplasty (TKA) requires a multidisciplinary approach. Optimal control of acute post-operative pain and the prevention of chronic persistent pain remains a challenge. The aim of this paper is to evaluate whether stratification of patients can help identify those who are at particular risk for severe acute or chronic pain. Intense ...
متن کاملIn the mind or in the brain? Scientific evidence for central sensitisation in chronic fatigue syndrome.
BACKGROUND Central sensitisation entails several top-down and bottom-up mechanisms, all contributing to the hyperresponsiveness of the central nervous system to a variety of inputs. In the late nineties, it was first hypothesised that chronic fatigue syndrome (CFS) is characterised by hypersensitivity of the central nervous system (i.e. central sensitisation). Since then, several studies have e...
متن کاملOpioids and central sensitisation: I. Preemptive analgesia.
Opioids are powerful analgesics when used to treat acute pain and some forms of chronic pain. A large body of literature has shown that opioids can, in addition, also prevent (this review) or induce and perhaps reverse, some forms central sensitisation in in vitro and in vivo animal models of pain. However, the concept of central sensitisation is, at present, ambiguous and the usefulness of opi...
متن کاملInteraction of NMDA and opioid receptors on thermal hyperalgesia and mechanical allodynia in two models of neuropathic pain
The use of multiple loose ligations of the rat sciatic nerve has been proposed as a model for the study of allodynia and hyperalgesia. This pain hypersensitivity results from both an increase in the peripheral and central sensitization. The evidence indicating that the development of neuropathic thermal hyperalgesia and mechanical allodynia requires activation of spinal cord NMDA receptors. NMD...
