Lubiprostone is an oral medication used for the treatment of idiopathic (due to an unknown cause) chronic constipation. Chronic constipation most commonly occurs because of slow transit of stool through the colon that allows too much fluid to be removed from the stool, leading to hard or lumpy stools, abdominal pain or discomfort, and straining during bowel movements, as well as difficulty passing stools. Signs and symptoms of chronic constipation can be reduced by increasing fluid in the stool. Lubiprostone causes an increase in the secretion of fluid into the intestines. The added fluid softens the stool and also may speed up transit of stool in the colon. Lubiprostone was approved by the FDA in January 2006.
