[24] Opiate is properly limited to the natural alkaloids found in the resin of the opium poppy although some include semi-synthetic derivatives.
Opioids act upon opioid receptors that are coupled to inhibitor G protein coupled receptors (GPCR). These receptors fall into 3 classes: μ (mu), δ (delta), and κ (kappa) receptors. [36] More than 70% of opioid receptors are μ receptors, predominantly located on the central terminals of nociceptors in the dorsal horn of the spinal cord.
