Similarly to μ-opioid receptor (MOR) agonists, KOR agonists are potently analgesic, and have been employed clinically in the treatment of pain. (wikipedia.org)
However, the analgesic efficacy of opioids is compromised by side-effects such as analgesic tolerance, dependence and opioid-induced hyperalgesia (OIH). (johnshopkins.edu)
These findings warrant further investigations that examine animal and human MORK1 expression and function following chronic exposure to opioids, which may identify MOR1K as a novel target for the development of new clinically effective classes of opioids that have high analgesic efficacy with diminished ability to produce tolerance, OIH, and other unwanted side-effects.

Furthermore, a single s.c. pre-treatment with (-)U-50,488H had no effect on the mu-opioid receptor agonist-induced antinociception. (hyperthermicwellness.com)
These results suggest that repeated stimulation of kappa-opioid receptors leads to the heterologous up-regulation of mu-opioid receptor functions in the thalamus and periaqueductal gray regions, which may be associated with the supersensitivity of mu-opioid receptor-mediated antinociception. (hyperthermicwellness.com)
