General Information

Naloxegol is used to treat constipation caused by narcotic medications. This is usually in people with on-going pain that is not caused by cancer. This blocks certain effects of opioid medication. Constipation is infrequent bowel movements or difficult passages of stools that persists for several weeks.

How does Naloxegol work?

Naloxegol functions as a peripherally-acting mu-opioid receptor antagonist in tissues such as the gastrointestinal tract. Therefore it lessens the constipating effects of opioids. Naloxegol works quickly within 6-12 hours of the first dose.

Why use Naloxegol?

Naloxegol belongs to a class of drugs called narcotic antagonists. This lessens constipation caused by narcotic medicine.
