They have several adverse gastrointestinal effects, one of which is opioid-induced constipation. The opioid analgesics produce analgesia by the activation of the mu receptors found in the CNS and PNS. These drugs affect the motility, tone, and contractility of the bowel functions, which results in the delay in the transit of fecal contents.
