Opioid-induced hyperalgesia (OIH) is defined as a state of nociceptive reports or diffuse allodynia unassociated with the original pain, and increased levels.

Hyperalgesia is amplified pain; processes in the nervous system work to increase the intensity of the pain you feel. Allodynia is pain that's caused by something that isn't normally painful, such as a light touch or fabric moving across your skin. Opioids are only available by prescription. Hyperpathia, hyperalgesia, and allodynia are three manifestations of central sensitization, a condition in which a higher than necessary degree of activity is triggered in the central nervous system. Generally, this activity is triggered by nocioception or the nervous system's normal response to painful stimuli.

NRS, hyperalgesia, and allodynia from 0 to 2 h were analyzed by AUC due to nonlinearity for time and analyzed by paired Wilcoxon Mann Whitney U test. Baseline milliampere to elicit an NRS of 6 as well as time to CPP threshold and CPP tolerance were considered to be continuous data and were analyzed using a paired Wilcoxon Mann Whitney U test. to mechanical hyperalgesia, the effect of indometha-cin against cold allodynia was only significant at 3 h. Further, zileuton displayed maximal reversal of cold allodynia of 78.36% (100 mg/kg) 3 h after administra-tion (PWL zileuton 2.45 ± 0.67 s vs. 0.51 ± 0.08 s for control) (Tab.

In an early definition hyperalgesia was considered “a state of increased intensity of pain sensation induced by either noxious or ordinarily nonnoxious stimulation of peripheral tissue.” Allodynia is a pain in response to a nonnociceptive stimulus (Sandkühler, 2009).
