Opioid-Induced Bowel Dysfunction
2008, Journal of Pain and Symptom ManagementCitation Excerpt :In the central nervous system, these mu receptor modulatory effects decrease neurotransmission. Direct recording from enteric neurons supports a similar inhibition of neuronal firing occurring in the GI tract also.18,19 Studies in various animals have demonstrated that under the influence of opioids, the outer longitudinal smooth muscle relaxes, but the inner circular smooth muscle has increased tone.16
