How Do Opioid Agonists Work?

Opioidagonists are medications used for the short-term management of moderate-to-severeacute pain. Opioid agonists relievepainby stimulating opioid receptors. Opioid receptors areproteinmolecules on神经细胞(神经细胞on) membranesinthecentralandperipheralnervous systems.

Opioid receptors mediate the body’s response to most hormones and some of their functions include modulating pain,stressresponse,respiration, mood, and emotion. Opioid agonists stimulate mu-opioid receptors, one of the five types of opioid receptors in the human body.

Opioid agonists work by binding to mu-opioid receptors and inhibiting the release of chemicals (neurotransmitters) that transmit pain signals between the neurons.

Opioid agonists are administered asintravenous(IV) injections, only in hospitals orhealthcare facilities. Opioid agonists are used to treating moderate-to-severeacutepain that is severe enough to require IV opioids when alternative treatments are inadequate.

• Nausea
• Vomiting
