Opioid receptors are a group of inhibitory G protein-coupled receptors with opioids as ligands. The endogenous opioids are dynorphins, enkephalins, endorphins, endomorphins and nociceptin. The opioid receptors are ~40% identical to somatostatin receptors (SSTRs).igma (Ï) receptors were once considered to be opioid receptors due to the antitussive actions of many opioid drugs' being mediated via Ï receptors, and the first selective Ï agonists being derivatives of opioid drugs (e.g., allylnormetazocine).
