Mechanism of action

Morphine is a mu-opioid receptor agonist that crosses the blood-brain barrier and acts on opioid receptors in the brain and spinal cord. This binding modulates pain signal transmission and produces analgesic, sedative, and euphoric effects. It is one of the oldest and most widely used opioid analgesics for moderate to severe pain management.
