What is the most common GI adverse reaction side effect of narcotics?
Opioid-induced constipation (OIC) is the most common and debilitating side effect of opioids. The concentration of opioid receptors in the GI tract is highly dense. Activation of these receptors, particularly mu receptors, inhibits gastric emptying, reduces mucosal secretions, and increases fluid reabsorption.
Is opioid-induced hyperalgesia real?
Opioid-induced hyperalgesia (OIH) is defined as a state of nociceptive sensitization caused by exposure to opioids. The condition is characterized by a paradoxical response whereby a patient receiving opioids for the treatment of pain could actually become more sensitive to certain painful stimuli.
Which common adverse effects is associated with opiate agonists?

Does opioid hyperalgesia go away?
The side effects will usually go away and you might need more medicine over time, stretched out over a long period of time to achieve the desired effect.
Which opioids are full agonists?
