Opioid-induced constipation in mixed chronic pain patients: Prevalence and predictors analysis

OIC was found in almost all evaluations of weak or strong opioidusers (97 percent); moderate to severe OIC was found in 72 percent of the evaluations. Cancer patients were associated with severe constipation. Macrogol was superior to other laxatives. In our experience, macrogol relieved constipation in those on the combination of oxycodone and naloxone and in those on fentanyl patches. Lactulose and glycerol suppositories were associated with severe constipation.
