Where do nonopioid analgesics primarily exert their effect compared with opioids?

Explanation:
Nonopioid analgesics exert their analgesic effect mainly at the site of injury. They blunt inflammatory mediators, like prostaglandins, in peripheral tissues, which reduces sensitization of local nociceptors and the transmission of pain signals from the injury site. Opioids, on the other hand, work predominantly in the central nervous system, binding to receptors in the brain and spinal cord to alter pain perception and modulate the ascending and descending pathways that control pain. So the key distinction is peripheral action at the site of pain for nonopioids versus central nervous system action for opioids.
