An opioid overdose results from over-activation of these receptors, which can cause permanent brain damage from cerebral hypoxia or neurotoxicity.

Oxycodone, a semi-synthetic opioid, is a highly selective full agonist of the μ-opioid receptor (MOR). [40] [41] This is the main biological target of the endogenous opioid neuropeptide β-endorphin. [18] Oxycodone has low affinity for the δ-opioid receptor (DOR) and the κ-opioid receptor (KOR), where it is an agonist similarly.
Chest wall. Wooden chest syndrome is a rigidity of the chest following the administration of high doses of opioids during anesthesia [1]. [1]Wooden chest syndrome describes marked muscle rigidity — especially involving the thoracic and abdominal muscles — that is an occasional adverse effect associated with the intravenous administration of lipophilic synthetic opioids such as fentanyl [2].
