Narcotic analgesics are known as narcotic agonists, and act on the central nervous system to provide relief from moderate and severe pain. Narcotic analgesics are also used to suppress coughing by acting on the respiratory and cough centers in the medulla of the brain stem.
Opioids are a category of narcotic analgesics. All relieve pain and all, except meperidine (Demerol), have an antitussive (cough suppression) and antidiar-rheal effect.
