Mechanism of action

Naloxone works by rapidly displacing opioids from their receptors in the brain and spinal cord, restoring normal breathing and circulation. This is achieved through competitive inhibition, where naloxone binds to the same receptors as opioids, preventing them from exerting their effects. As a result, naloxone can quickly reverse the life-threatening symptoms of opioid overdose.
