Morphine belongs to a class of medications called opiate (narcotic) analgesics. Morphine works by changing the way the brain and nervous system respond to pain; it does this by binding to the mu-opioid receptors within the central nervous system (CNS) and the peripheral nervous system (PNS).
Morphine binding to opioid receptors blocks transmission of nociceptive signals, signals pain-modulating neurons in the spinal cord, and inhibits primary afferent nociceptors to the dorsal horn sensory projection cells. 1
