Question

Quizplus · Accepted Answer

Nonopioid analgesics differ from opioid analgesics in four ways. First, these analgesics are not chemically or structurally related to morphine (nor are they related to each other by a common structure). Second, they are not effective against severe, sharp visceral pain. Third, they produce analgesia through both a central (central nervous system [CNS]) and a peripheral (site of injury) mechanism of action. Fourth, they do not produce tolerance or physical dependency with chronic use.
