Opioids are a cornerstone of modern pain management, but their powerful effects are mediated by a complex system. So, what are the three main opioid receptors that these drugs target? Understanding them is key to grasping both their benefits and their risks.

Opioid receptors were first identified in the brain in the 1970s, revolutionizing our understanding of pain and addiction. This knowledge is fundamental to grasping **what are the 4 opioid receptors** and how they modulate a wide spectrum of physiological responses, from powerful analgesia and euphoria to stress and anxiety.
