Opioid-induced bowel dysfunction: a literature review

Abstract

Opioid therapy plays a crucial role in the management of acute and chronic pain, with opioids being widely prescribed worldwide. However, alongside the analgesic benefits, the use of opioids is associated with a range of adverse effects, including opioid-induced bowel dysfunction. Opioid-induced bowel dysfunction refers to a constellation of gastrointestinal symptoms caused by the effects of opioids on the gastrointestinal tract. These symptoms primarily manifest as constipation, but can also include abdominal pain, bloating, nausea, and vomiting. Opioid-induced bowel dysfunction poses a significant clinical challenge, as it can severely affect patients' quality of life. Non-pharmacological approaches alone are rarely sufficient to counteract the adverse effects of opioid therapy. The primary pharmacological agents used in opioid-induced bowel dysfunction management are laxatives, which should be chosen according to individual patient needs. Patients with poorly controlled symptoms can benefit from new pharmacological approaches, particularly peripheral mu-opioid receptor antagonists. By better understanding the underlying mechanisms, clinical manifestations, diagnostic criteria, and management strategies, healthcare professionals can optimize patient care, minimize complications, and improve patients' overall well-being.
