opioid analgesics

Summary

Summary: Narcotic or opioid substances, synthetic or semisynthetic agents producing profound analgesia, drowsiness, and changes in mood. Mood changes may be pleasurable, therefore creating a potential for the abuse of these agents; the prototype of these is morphine to which all other analgesics are compared.
