Mechanism of action

Opioids are agonists at mu, delta, and kappa opioid receptors, with mu-receptor activation being the primary mechanism for analgesia. By binding to these G-protein coupled receptors, they inhibit neurotransmitter release and hyperpolarize neurons, reducing pain signal transmission. IV administration provides rapid onset and is used for acute, moderate-to-severe pain management in clinical settings.
