What is the main effect of opioids?

Explanation:
Analgesia is the primary clinical effect of opioids. They activate mu opioid receptors in the central nervous system, which dampens the transmission of nociceptive signals in the spinal cord and brain and alters the subjective experience of pain. This results in strong relief from moderate to severe pain. Other effects like mood elevation can occur because opioids also influence reward pathways, but these are secondary to the pain-relieving action. Nausea is a common side effect from chemoreceptor trigger zone stimulation and GI slowing, and increased heart rate is not the defining effect of opioids.
