About the introduction of lubiprostone:

●Uses:

This medication is used to treat certain types of constipation (chronic idiopathic constipation, irritable bowel syndrome with constipation). Chronic idiopathic constipation has an unknown cause and is not due to diet, other diseases, or drugs.
Lubiprostone is also used to treat constipation caused by narcotic (opiate-type) medications in people with ongoing pain due to medical conditions other than cancer.
This medication may improve symptoms such as bloating and abdominal discomfort, improve stool texture, lessen the need to strain, and decrease the feeling of not completely relieving oneself. Lubiprostone belongs to a class of drugs known as chloride channel activators. It works by increasing the amount of fluid within your intestines, making the passage of stool easier.
