Peripherally acting mu-opioid antagonists are expensive, and should be used only when other options are ineffective.īharucha AE, Pemberton JH, Locke GR. Naloxegol is administered orally and is approved for opioid-induced constipation in patients who do not have cancer. Alvimopan, approved for short-term treatment of postoperative ileus, is available only through a restricted prescribing program because of increased risk of myocardial infarction. 34 Methylnaltrexone should not be used in patients with intestinal obstruction and should be used with caution in patients with intestinal malignancy. 23 Methylnaltrexone is administered subcutaneously and is effective for opioid-induced constipation in palliative care patients with symptoms resistant to other laxatives. 33 A systematic review of studies with patients up to 78 years of age who had malignant or nonmalignant pain found that methylnaltrexone, naloxone, and alvimopan were more effective than placebo for chronic opioid-induced constipation. Up to 40% of patients taking opioids are constipated of these, only 46% have an acceptable response to laxatives more than 50% of the time. These agents include methylnaltrexone (Relistor), alvimopan (Entereg), and naloxegol (Movantik), which decrease the gastrointestinal effects of opioids without reducing centrally mediated analgesia, and naloxone, which is also effective for constipation but can decrease analgesia.

The next step in the treatment of constipation is the use of an osmotic laxative, such as polyethylene glycol, followed by a stool softener, such as docusate sodium, and then stimulant laxatives. Fiber intake should be slowly increased over several weeks to decrease adverse effects. Additional fiber intake in the form of polycarbophil, methylcellulose, or psyllium may improve symptoms. ![]() Most patients are initially treated with lifestyle modifications, such as scheduled toileting after meals, increased fluid intake, and increased dietary fiber intake. Fecal impaction should be treated with mineral oil or warm water enemas. Secondary constipation is associated with chronic disease processes, medication use, and psychosocial issues. Primary constipation is also referred to as functional constipation. Chronic constipation is common in adults older than 60 years, and symptoms occur in up to 50% of nursing home residents.
