Tsukuba, Japan—Pain relief for patients with cancer is crucial, and opioids, such as morphine, play a vital role. However, constipation, which negatively affects the patient's quality of life, is a common side effect of opioid administration. This condition, also known as opioid-induced constipation, is prevalent and frequently does not resolve on its own, thereby necessitating effective interventions.
This study aimed to investigate the effects of naldemedine, a medication used to treat constipation, in preventing constipation when patients with cancer begin receiving opioids. Naldemedine is anticipated to prevent constipation by promoting regular bowel movements.
The study involved 99 patients with cancer, categorized into two groups: one receiving naldemedine and the other a placebo. After 14 days of treatment, 64.6% of the patients taking naldemedine showed no signs of constipation compared with 17.0% in the placebo group. Furthermore, the naldemedine group demonstrated improved quality of life and reduced nausea.
In conclusion, the study indicates that naldemedine, when administered in conjunction with opioids for pain relief in patients with cancer, contributes to a more comfortable life by preventing constipation.
