Methylnaltrexone for Opioid-induced Constipation

What is Methylnaltrexone?

Methylnaltrexone is a medication used to treat opioid-induced constipation (OIC). OIC is a common side effect of opioid pain medications, which can slow down bowel movements and cause difficulty passing stools. Methylnaltrexone works by blocking the action of opioids on the gut, allowing the bowel to function normally again.

How Does Methylnaltrexone Work?

Methylnaltrexone is a peripherally acting mu-opioid receptor antagonist, meaning it blocks the action of opioids on the gut without affecting their pain-relieving properties in the brain. By doing so, it allows the bowel to function normally, reducing the risk of constipation. This is particularly important for patients who are taking opioids for chronic pain management, as constipation can be a significant source of discomfort and distress.

What are the Benefits of Methylnaltrexone?

Methylnaltrexone has been shown to be effective in treating OIC in patients taking opioids for chronic pain. It can help to improve bowel function, reduce the risk of constipation, and improve overall quality of life. Additionally, methylnaltrexone is administered via injection, which can be more convenient for patients than other treatments for OIC.
