Opioids work on what receptors in the brain Mu = brainstem and thalamus
Kappa = limbic, brain stem, spinal cord
Delta = brain
What are the effect of opioids on mu receptors Mu 1 = analgesia
Mu 2 = sedation, vomiting, respiratory depression, pruritis, euphoria, anorexia, urinary
retention
What are the effects of opioids on Kappa receptors Analgesia, sedation, dyspnea,
psychomimetic effects, miosis, respiratory depression, euphoria, dysphoria
