Document Summary

10b: analgesics 2 : describing the therapeutic effects of narcotic pain relievers, opioids (narcotics) drugs that work by binding to opioid receptors in the brain, spinal cord, and other areas of the body. They reduce the sending of pain messages to the brain and reduce the feelings of pain. Used to treat moderate to severe pain that may not respond well to other pain medications. Opioid analgesics relieve pain by acting directly on the central nervous system. Opioids are unique in that they not only block the transmission the incoming painful stimuli to the brain but also act at higher brain centers, controlling the affective components of the pain.
